Notation in this Manual

This manual uses the following notation.

• “Loop Controller” is used as a generic term to refer to the L oop Controllers i n general.

•“LCB@@” is used to refer to specific Loop Controller functional elements. For example, the Loop Controller function element in a CS1W-LCB05 Loop Control Board is the LCB05, so “LCB05” is used to ref er to th e Loop Controller functional element. The Loop Controller function element in a CJ1GCPU44P Loop-control CPU Unit is the LCB03, so “LCB03” is used to refer to the Loop Controller functional elem ent.

• Model numbers are used to refer to specific Loop Controller models.

In the CX-Process Tool Operation Manual for version 3.2 or lower, functional element names (LCB@@) are given as “Loop Control Board.” In the CX-Pro- cess Tool Operation Manual for version 4.0 or higher, simply “LCB@@” is used.

Safety Precautions 3

3 Safety Precautions

!WARNING Do not attempt to take any Unit or Board apar t while power is being supplied.

Doing so may result in electric shock.

!WARNING Do not touch live terminals. Electric shock will result.

!WARNING Provide safety measures in external circuits (i.e., not in the Programmable

Controller), including the following items, to ensure safety in the system if an abnormality occurs due to malfunction of the PLC or another external factor affecting the PLC operation. Not doing so may result in serious accidents.

• Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits.

• When using a CS1D-CPU@@P Process-control CPU Unit, the CS1D Duplex System will stop operating and all outputs will be turned OFF in the following cases:

• The self-diagnostic function detected errors at the same time in both the active side (CPU Unit or Loop Controller) and the standby side (CPU Unit or Loop Controller).

• A SEVERE F AILURE ALARM (FALS) instruction is executed and generated fata l errors at the same time in both the a ctive CPU Unit and t he standby CPU Unit.

• The self-diagnostic function detected an error while operating in simplex mode or performing duplex initialization in duplex mode.

• A SEVERE FAILURE ALARM (FALS) instruction was executed and generated a fatal error while operating in simplex mode or performing duplex initialization in duplex mode.

Unexpected operation, however, may still occur for errors in the I/O control section, errors in I/O memory, and other errors that cannot be detected by the self-diagnosis function. As a countermeasure for all such errors, external safety measures must be provided to ensure safety in the system.

• When a CS1W-LCB01 or CS1W-LCB05 Loop Control Board is mounted in a CS1-H CPU Unit, the CPU Unit will stop operating and all outputs will be turned OFF if the self-diagnostic function detected an error or a SEVERE FAILURE ALARM (FALS) instruction was executed. As a countermeasure for such errors, external safety measures must be provided to ensure safety in the system.

• The PLC outputs may remain ON or OFF due to depos ition or burning o f the output relays or destr uction of the output transistors. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system.

• When the 24-V DC output (service power supply to the PLC) is overloaded or short-circuited, the voltage may drop and result in the outputs being turned OFF. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system.

!WARNING Check the following items before starting to run the Loop Controller:

xxv

Safety Precautions 3

• Do not allow the bank of the EM Area wit h the number specified f or a llocation to the HMI (human-machine interface) data to overlap with any other area used by the CPU Unit or other Units. The block allocated for the HMI is specified in ITEM 050 (EM Area Bank Allocated for HMI Memory = 0 to

12) of the System Common block (Block Model 000). If areas overlap, the system may operate in an unexpected manner, which may result in injury.

• Do not allow the area to which user link table data is written to overlap with any other area used by the CPU Unit or other Units. If areas over lap, the system may operate in an unexpected manner, which may result in injury.

• When using a user link table to write bit data to I/O memor y in the CPU Unit. Never allow ladder programming or communications processes in the CPU Unit to write to any bits in the words in which bits are written from a user link table. Depending on the timing, any attempts to write to these words from ladder programming or communications processes may be ignored. Example: If tag A in a user link table writes to bit 00 of W000 and an OUT instruction in the ladder program in the CPU Unit write to bit 01 of W000, the write from the ladder program may be ignored.

• Analog Input/Output Units used in combination with the Loop Controller must be mounted correctly, and the unit number set on the front panel of the Analog Input/Output Unit must match the unit number set on the Field Terminal block. If the unit numbers do not match, input/output (read/write) is performed on the data of another Special I/O Unit (whose unit number is set on the Field Terminal block).

• The defaults of the System Common block on the Loop Controller must be set correctly.

• Always stop the operation of the Loop Controller before converting any of the EM Area to file memory. If any part of the EM Area that is being used by the Loop Controller for the s is converted to file memory during Board operation, the system may operate in an unexpected manner, which may result in injury.

!WARNING Do not use battery-fr ee operation for the CS1-H CPU Unit or the CPU Unit

element of a Process-control CPU Unit or Loop-control CPU Unit. If batteryfree operation is used for the CPU Unit or CPU Unit element, the contents of the EM Area will not be stable when the power supply is turned ON, possibly causing illegal values in the HMI data in the Loop Controller.

!WARNING Do not perform processing in such a way that the Loop Controller and CPU

Unit perform writing on identical I/O memory addresses allocated to an contact output or analog output to an e xternal Unit. If writing is perf ormed on identical addresses, the externally connected load may act unexpectedly and cause injury.

xxvi

Safety Precautions 3

!WARNING The Loop Controller will automatically start using a cold star t even if the star-

tup mode is set to a hot star t if the power is turned ON after being OFF for 24 hours or longer. If this happens, the auto/manual setting for the Control Block will be set to manual mode (MV=0%) and the remote/local setting will be set to local. To automatically switch to auto mode at th e same time as starting operation after the power is turned ON after being OFF for 24 hours or longer, the ladder diagrams in the Sequence Table or Step Ladder Program blocks must be programmed as follows (same as the procedure for switching to remote operation): Processing: ITEM 086 (Auto/Manual switch) of the Basic PID block or Advanced PID block is set to 1 using ITEM019 (Run Start Flag) and ITEM017 (cold start in progress) of the System Common block as the input conditions.

For details on hot and cold start operations, refer to 3-2-3 Details of Hot Start, Cold Start and Stop State.

!WARNING When using the CS1D-CPU@@P Process-control CPU Unit, both the CPU

Unit’s cycle time and the Loop Controller’s operation cycle will be temporarily longer than normal during duplex initialization (i n duple x mode). The extended cycle time and operation cycle may temporarily worsen the control characteristics, so verify the system’s operation in test runs before actually running the system.

!Caution When downloading a sequence table for the Loop Control Board (version 1.5

or higher) that has been edited online with the CX-Process Tool version 3.2 or higher, confirm that the system will operate normally with the edited sequence. If the sequence is not suitable for operation, unexpected operation may result.

xxvii

Operating Environment Precautions 4

!Caution Confirm in advance the conditions at an y node for which the sequence table is

being edited over a Controller Link or Ethernet network. Not doing so may result in unexpected operation.

!Caution Do not use the HMI function to write a value that is ou tside of the data range

shown in the ITEM list in the Function Block Reference Manual (Cat. No. W407) to the receive area (CPU Unit to Loop Controller) in the EM Area. Writing an out-of-range value can result in unexpected operation by the controlled machine or equipment.

!Caution When executing calibration functions, the MV (manipulated variable) will be

changed when the PV (process value) is changed in the control block. Therefore, before executing this function, make sure that the equipment will be safe even if the MV changes by setting pseudo-inputs. Otherwise, unexpected equipment operation may result, causing a serious accident.

4 Operating Environment Precautions

4-1 CS1D-CPU@@P Process-control CPU Unit Precautions

• Normal operation will be possible only if the CS1D-CPU@@P Processcontrol CPU Unit is used in the combination in which it was shipped. Normal operation may not be po ssible if the CS1D-CPU@@P Process-control CPU Unit is used in any other combination. Therefore, do not remove the Loop Controller component from the CPU Unit. Always replace the entire CS1D Process-control CPU Unit as on e Unit even if only the Loop Controller or CPU Unit has failed.

• The CS1D CPU Unit’s cycle time and the Loop Controller component’s LCB load rate are different in duplex mode and simplex mode. Verify the system’s oper ation in bo th modes in trial opera tion before actually running the system.

• When replacing a CS1D Process-control CPU Unit while powe r is supplied to the PLC, always switch the DPL Unit’s CPU U SE/NO USE switch to “NO USE.” Removing the CS1D Process-control CPU Unit with the switch set to “USE” (power supplied) may damage the CPU Duplex Backplane, CS1D CPU Unit, DPL Unit, and Loop Controller component of the Process-control CPU Unit.

4-2 CS1W-LCB01/CS1W-LCB05 Loop Control Board Precautions

Do not use a CS1W-LCB01 or CS1W-LCB05 Loop Control Board in any CPU Unit other than the CS1-H.

• If a CS1W-LCB01 or CS1W-LCB05 Loop Control Board is used in a CS1 CPU Unit, a non-fatal INNER Board error will occur and the Loop Control Board will not operate. (The CPU Unit itself will be able to operate.)

• If a CS1W-LCB01 or CS1W-LCB05 Loop Control Board is used in a CS1D CPU Unit, a fatal INNER Board error will occur. (In this case, neither the Loop Control Board nor the CPU Unit will operate.)

• Loop Control Boards before version 1.5 cannot be used with CS1DCPU@@S CS1D CPU Units for Single-CPU Systems.

• Do not connect pin 6 (+5 V power supply line) of the RS-232C port on the CPU Unit to any external device except the CJ1W-CIF11 RS-422A Adapter or NT-AL001 RS-232C/RS-422A Adapter. Doing so may damage the external device or Loop Control Board.

Application Precautions 5

4-3 Precautions for All Loop Control Boards, Process-control CPU

Units, and Loop-control CPU Units

!Caution Do not operate the control system in the following places:

• Locations subject to direct sunlight

• Locations subject to temperature or humidity outside the range specified in the specifications

• Locations subject to condensation as the r esult of severe changes in temperature

• Locations subject to corrosive or flammable gases

• Locations subject to dust (especially iron dust) or salts

• Locations subject to exposure to water, oil, or chemicals

• Locations subject to shock or vibration

!Caution Take appropriate and sufficient countermeasures when installing systems in

the following locations:

• Locations subject to static electricity or other forms of noise

• Locations subject to strong electromagnetic fields

• Locations subject possible exposure to radioactivity

• Locations close to power supplies

!Caution The operating environment of the PLC System can have a large effect on the

longevity and reliability of the system. Improper operating environments can lead to malfunction, failure, and other unforeseeable problems with the PLC System. Be sure that the operating environment is within the specified conditions at installation and remains within the specified conditions during the life of the system.

5 Application Precautions

Observe the following precautions when using the PLC.

!WARNING Always heed these precautions. Failure to abide by the following precautions

could lead to serious or possibly fatal injury.

• Always turn OFF the power to the PLC before attempting any of the following. Not turning OFF the power may result in malfunction or electric shock.

• Mounting or dismounting I/O Units, including Inner Boards

• Assembling the Racks

• Setting DIP switches or unit number setting switches

• Connecting or wiring the cables

• Connecting or disconnecting the connectors

!Caution Failure to abide by the following precautions could lead to faulty operation of

the PLC or the system, or could damage the PLC or PLC Units. Always heed these precautions.

xxix

Application Precautions 5

• If the power supply is turned OFF while function block data is being backed up from RAM to flash memory, the backup will not be completed normally. If the power supply is turned back ON within 24 hours, however, the super capacitor will have held the RAM data. The backup operation will restart when power is turned ON and operation will start when the backup has been completed. If the power supply is turned OFF for more than 24 hours, however, RAM data will be lost and operation will be started with the data that was previously saved to flash memory. If this happens, the Cold Start Auto-execution Flag (A35807) will turn ON to show that the previous data has been used. Use this bit in programming to take whatever steps are necessary, such as downloading the most recent function block data.

• To hold analog outputs o r contact outp uts at spec ific values (for example, maximum value or minim um v alue ) when the Loop Controller has stop ped running, create a Step Ladd er Program on the CPU Unit so that each of the allocated bits on the Analog Output Unit or Contact Output Unit are set to a specific value taking the N.C. condition of the Loop Controller Running flag (A35801) as the input condition.

• When a fatal error occurs on the CPU Unit (including execution of the FALS instruction), the Loop Controller also stops running. To hold the analog output to the previous value before the stop occurred, and to set the analog output to either the minimum value or maximum value, use the output hold function of the Analog Output Unit or Analog Input/Output Unit.

• Before turning ON the power to the PLC, make sure that the facilities are safe.

• The analog output values and contact outputs from the Loop Controller are updated at the same time that the power to the PLC is turned ON regardless of the operation mode of the CPU Unit (including the PROGRAM mode). (Internally, the analog output values and contact outputs are sent via the CPU Unit to the Basic I/O Unit and Analog Output Unit.)

• The Loop Controller itself does not have a human-machine interface. So, an external interface such as SCADA software must be provided.

• Fail-safe measures must be taken by the customer to ensure safety in the event of incorrect, missing, or abnormal signals caused by broken signal lines, momentary power interruption s or other causes.

• Before touching the PLC, be sure to first touch a grounded metallic object in order to discharge any static build-up. Otherwise, it might result in a malfunction or damage.

• Take appropriate measures to ensure that the specified power with the rated voltage and frequency is supplied. Be particularly careful in places where the power supply is unstable. An incorrect power supply may result in malfunction.

• Do not attempt to disassemble, repair, or modify any Units or Boards.

• Leave the dust-protection label attached to the top Unit when wiring. Removing the label may result in malfunction.

• Remove the label afte r the co mpletio n of wiring to ensure proper heat dissipation. Leaving the label attached may result in malfunction.

• Check the user program for proper execution before actually running it on the Unit or Board. Not checking the program may result in an unexpected operation.

xxx

EC Directives 6

• Double-check all the wiring before turning ON the power supply. Incorrect wiring may result in burning.

• Tighten the PLC Backplane mounting screws, terminal block screws, and cable (connector) screws to the torque specified in user manuals.

• Confirm that no adverse effect will occur in the system before attempting any of the following:

• Changing the operating mode of th e PLC

• Force-setting/force-resetting of any contact in memory

• Changing the present value or any set value in memory

6 EC Directives

CS-series products confirm to EC Directives. For th e system to conf o rm to EC Directives, however, the following precautions must be adhered to.

• CS-series Units must be installed within control panel.

• Use reinforced insulation of double insulation for the DC power supplies used for the I/O power supplies.

• CS-series products that meet EC Directives also meet the Common Emission Standard (EN61000-6-4). The measure necessary to ensure that standards, such as the radiated emission standard (10 m), are met, however, will vary depending on the overall configuration of the control panel, the other devices to the control panel, and wiring. You must therefore confirm that EC Directives are me t for the overall machine or device.

• EMC Directive

• Low Voltage Directive

EMC and Low Voltage Directives

EMC Directive

In order that OMRON products can be used with an y machine ry and in combination with other manufacturer's equipment, the products themselves are designed to comply with EMC standards (see Note), so that the assembled machinery or device can then also easily comply with EMC standards.

Even if machinery and equipment complies with EMC standards before assembly, this compliance may change depending on the device, the configuration of the control panel, and wiring, so OMRON cannot guarantee that a particular system complies with the directive. You must therefore confir m that EMC Directives are met for the overall machine or device.

Note EMC: One directive relating to Electro-Magnetic Compatibility

Var ious process operations, including PID control, can be performed for up to 500 blocks with the LCB05 and LCB05D, up to 300 blocks with th e LCB03, or up to 50 blocks with the LCB01. (See note.) Process operations include basic logic sequence control and step-progression control. The Loop Controller can also be used to implement an alarm/monitor terminal on a computer without using PID control functions.

Note The maximum number of control loops is determined by the operation cycle.

In most cases, such as when each loop consists of an Ai4 Terminal, a Segment Linearizer, a Basic PID, and an Ao4 Terminal block the maximum number of control loops would be as shown in the following tables.

The Loop Control Boards, Process-control CPU Units, and Loop-control CPU Units have no external I/O functions. So, they must be used in a pair with a Unit having an external interface, such as an Analog I/O Unit or Basic I/O Unit. The Loop Controller exchanges data with the Unit having the external interface via the CPU Unit I/O memory.

You can achieve all functions (operation functions/designation of field input/output) simply by combining Control blocks, Operation blocks, and other function blocks. This allows you to easily build a professional instrumentation system on your PLC (Programmable Controller).

The following f unctions can be achieved by function blocks:

Internal Operations • Control and operation blocks (500 function blocks max. for LCB05 and

LCB05D (See note.), 300 function blocks max. for LCB03, or 50 function blocks max. for LCB01): 2-position ON/OFF, Basic PID, Advanced PID, Ratio Setting, Alarm/Signal Restrictions/Hold, Arithmetic (addition, subtraction, multiplication and division), Functions (Square Root, Absolute Value, Segment Linearizer, etc.), Time Functions (Lead/Delay, Dead Time, Ramp Program, etc.), Pulse Train Operation (Accumulator), Signal Selection/Switching (Rank Selector, Constant Selector, etc.), Sequential Control (Timers, Counter, etc.)

Note Only 100 function blocks can be used on the LCB05 and LCB05D

if Fuzzy Logic, Arithmetic Operation, or Time Sequence Data Statistics blocks are used.

• External controllers (32 function blocks max.): ES100X Controller Terminal (Cannot be used on the CS1D-CPU@@P and CJ1G-CPU@@P.)

• Logic sequence/step progression control (200 function blocks max. for LCB03, LCB05, and LCB05D, 20 blocks max. for LCB01. 2,000 commands in total.): Step Ladder Program and sequence table (LCB05 and LCB05D only)

External I/O • Each of the points on the Analog I/O Unit and Basic I/O Unit is read and

written by the Field Terminal block (max. 80 function blocks).

• Specified contacts or analog data in the CPU Unit I/O memo ry is read and written by user link tables.

• Data for Control, Operation, and External Controller blocks can be read and written for SCADA software using the HMI function.

Note The CMND instruction can be executed in the ladder program in the CPU Unit

to send FINS commands to the Loop Controller to read and write function block data.

Outline Section 1-1

Loop Control Boards Loop Control Boards (CS1W-LCB01 and CS1W-LCB05) are classified as CS-

series Inner Boards. The CS1W-LCB01 and CS1W-LCB05 Loop Control Boards must be mounted in a CS1-H CPU Unit. (They will not operate and cannot be used in a CS1 CPU Unit.)

Loop Control Boards before version 1.5 cannot be used with CS1D-CPU@@S CS1D CPU Units for Single-CPU Systems.

The following table shows available Loop Control Board models.

Process-control CPU Units

The Process-control CPU Unit (CS1D-CPU@@P) is a CS1D CPU Unit for CS1D Duplex Systems. It consists at a Duplex Loop Control Board mounted in a CS1D CPU Unit. The Duplex Loop Control Board cannot be purchased as separate products. The Board is sold only when mounted in a CS1D CPU Unit as a set called the CS1D-CPU@@P Process-control CPU Unit.

The Duplex Loop Control Boards (Inner Boards) included with Process-control CPU Units cannot be removed and mounted in other CS1D CPU Units.

Note For duplex operation, always use two CS1D Process-control CPU Units of the

same model mounted to a CPU Duplex Backplane. The following table shows available Process-control CPU Units models.

1-1-2 Features

Common Features of Loop Controllers

High-speed Execution of Function Blocks for Multi-loop Control with an Operation Cycle of 10 ms

Function blocks are executed at high speed approximately ten times faster than for the Loop Control Units. For example, with a standard loop containing an Ai4 Terminal, a Segment Linearizer, a Basic PID, and an Ao4 Terminal block, 20 loops can be executed in 10 ms (except for the CS1D-CPU@@P).

All Functions Achieved by Using Only Function Blocks (Operation Functions/Designation of Field Input/Output)

Wiring function blocks in the sof tware allows you to achieve not o nly combinations of operation blocks but also all functions including specification of field I/O.

Almost All Control T ypes Freel y Achieved b y Combining Function Blocks

In addition to regular PID control, cascade control, feedforward control, dead time compensation control, override control and other special control types can be achieved as desired by combining function blocks for up to 250 loops for the LCB03, LCB05, and LCB05D or 50 loops for the LCB01. Control can also be easily configured for processes with prolonged dead time, non-linear processes, and processes involving fluctuating loads. Changes in control type after start of operation can also be flexibly accommodated.

Function Blocks with High-speed Execution

Operation cycles for control, ope ration, and other function b loc ks can be se t to 10 ms, 20 ms, or 50 ms as well as to longer per iods. The shortest operation cycle that could be set for Loop Control Units was 100 ms. With faster execution, for example, four loops of PID control can all be executed in a 10-ms operation cycle.

Outline Section 1-1

Note Operation cycles of 10 ms, 20 ms, and 50 ms cannot be set for the CS1D-

CPU@@P.

High-speed I/O Refreshing with the CPU Unit Using User Link Tables

User link tables can be set to refresh cycles of 10 ms, 20 ms, or 50 ms, and the Loop Controller with refresh data with the CPU Unit at the specified cycle. With this speed, the Loop Controller can quickly (within one cycle time) refresh contact and analog value s.

Note With the Loop Control Unit, there was a delay of up to 2 cycle times for field

terminal blocks (e.g., Di, Do, Ai, and Ao).

Designate I/O Memory in the CPU Unit Using Registered Tags

User-specified tags and CPU Unit data exchange conditions (such as I/O memory addresses) can be registered in user link tables on the CX-Process Tool. The tags registered in a user link table is u sed to pe rform data exchange with the CPU Unit on the specified refresh cycle. In seque nce tab les and other function blocks, tags can then be used to specify CPU Unit I/O memory (or bit or analog I/O values).

User link tables can also be pasted into block diagrams as virtual blocks, or tags can be automatically registered in the user link table when a field terminal block is pasted.

Note User link tables provide the same type of functionality as expanded CPU ter-

minals do in Loop Control Units. With the previous method, however, it was necessary to use expanded CPU terminals or CPU terminals to achieve data exchange with the CPU Unit, ma king it necessary to keep trac k o f I/O memory addresses in the CPU Unit and function block ITEM numbers in expanded CPU terminals or CPU terminals.

Execute Sequence or Step-progression Control Using Sequence Tables (CS1W-LCB05 Only)

In process control, the commonly used sequence control operations are often written in sequence tables. With a LCB@@, you can select either step ladder programming, the same method used b y Loop Control Un its , or use sequence tables, whichever you prefer.

Process progression for step transition (even to other tables), timer/counter functions, wiring to function block ITEM variables, or comparison operations using relational expressions are al so supported for sequence tables.

Simulated Software Connections between Function Blocks

CX-Process Tool allows you to simulate wiring between function blocks in the software by joining lines on your computer's screen.

Specify the Order of Operations in Function Block Diagrams

ITEMs can be set in function blocks in block diagrams to specify the order of processing control and operation blocks. (Blocks are processed left to right and then top to bottom by default.) With Loop Control Units, operation blocks were processed first followed by control blocks in the order of block addresses.

Easily Create a SCADA Interface with the HMI Function

Space for HMI data for control, operation, and external controller blocks is automatically allocated in the specified bank of the EM area. The bank number is specified in the System Common block.

With SCADA software, the HMI data in the control, operation, and external controller blocks can be read and written by specifying the CSV tags.

Outline Section 1-1

Note The HMI functions corresponds to the Receive All (Block Model 461) and

Send All (Block Model 462) blocks in the Loop Control Units. It is also possible to add tags from the user link table as CSV tags following

the HMI tags. Doing so enables using User Link Table tags from the SCADA software to read and write CPU Unit I/O memory.

Connect ES100X Controllers Externally (CS1W-LCB01/05 Only)

ES100X Controllers can be connected to the RS-232C port on the Loop Controller and ES100X Exter nal Controller Ter minal function blocks can be used to monitor ES100X parameters, such as the SP, PV, and MV, and to set ES100X parameters, such as the SP and PID constant s . Converting from RS232C to RS-422A/485 enables connecting up to 32 ES100X Controllers.

Message Communications by FINS Commands

Data on each of the function blocks can also be read and written as desired by issuing FINS commands by the CMND (DELIVER COMMAND) command in the Step Ladder Program on the CPU Unit or by issuing FINS commands from the host computer . Functi on bl ock da ta can also be r ead and written from PLCs (CPU Units) on other networked nodes.

Process-control CPU Unit Features (CS1DCPU@@P Only)

Note When using a Process-control CPU Unit (CS1D-CPU@@P), the function block

Duplex Systems

In a duplex system with two CS1D Process-control CPU Units, the Processcontrol CPU Unit (CS1D-CPU@@P) will continue to operate even if a fatal Inner Board error occurs in the Loop Controller of one Process-control CPU Unit. The system will switch to the Loop Controller of the other Process-control CPU Unit and Loop Controller operation (loop control) will continue. Furthermore, when the cause of the error is removed, the Loop Controllers will automatically reset to the original duplex operation status, just like duplex CPU Units. This makes the Loop Controllers of Process-control CPU Units suitable for 24-hour continuous operation systems.

operation cycle must be a minimum of 5 times the CS1D CPU Unit cycle time and also must be set to either 100 ms, 200 ms, 500 ms, 1 s, or 2 s.

1-1-3 LCB01/05 Version 1.5 Upgrade Information

The following funct ions have been added to the LCB01/05 with the upgrade to version 1.5.

Change Sequences during Sequence Execution (Supported by CX-Process Tool Version 3.2 or Higher)

When validating sequence tables, sequence tables can be edited online while the Loop Controller and sequence tables are operating. Sequence table operation continues even after the sequence tables have been edited online and downloaded.

To perform this function, select Edit - Start from the Sequence Table Action Validation Screen, and after editing the table, select Edit - Download.

Note Previously, sequence tables could be downloaded one at a time while the

Display PVs and Change SPs for Timers and Counters in Sequence Tables (Supported by CX-Process Tool Version 3.2 or Higher)

Loop Controller was operating. After downloading, however, the tables would be executed from step 1. As a result, operation did not continue during the time the tables were downloading.

When validating sequence tables, the present values of eleme nts (timer s and counters) are displayed. The set values for the elements (timers, counters) can also be changed during operation of the Loop Controller and sequence tables.

Outline Section 1-1

PID Constant Bank Selector Block (Block Model 168)

Split Converter Block (Block Model 169)

The PID constant bank selection function supported by OMRON Thermac Rseries Temperature Controllers can now be used simply with PLCs. The Bank Selector block (Block Model 168) is used together with the Basic PID block (Block Model 011), Advanced PID block (Block Model 012), or Blended PID block (Block Model 013).

Up to 8 sets (bank numbers 1 to 8) can be r ecorded f or ea ch of the P, I, D , MH, ML, and local SP values. The bank numbers can be switched and the recorded bank data can be written all at once to the P, I, D, MH, ML, and local SP values in the Basic PID or Advanced PID block at the connection destination, according to the analog input range or the ON status of input bits 1 to 8.

The autotuning results of Basic PID and Advanced PID blocks can also be reflected in the PID setting for the current bank.

The Split Conver ter block (Block Model 169) is used in combination with the Basic PID block (Block Model 011) or Advanced PID block (Block Model 012). The MV output value is converted into two analog outputs f or V characteristics or parallel characteristics (e.g., MV f or heatin g and MV f or cooling) and outpu t.

Both a heating side PID SP and coolin g side PID SP are provided, and the PID block SP at the MV connection source can be changed according to whether the output is for heating or cooling. Conversely, autotuning results for the PID blocks can also be reflected in either the PID constant for heating or cooling.

This block simplifies cont inuous pro portional control fo r heating/coo ling, which previously needed to be combined with segment approximation.

Disturbance Overshooting Suppression

Note This function is disabled during autotuning, while changing the target value

MV Limit Alarm Stop Switch

MV Error Control Stop Switch

Calculate High Speeds with Ramped Switch (Block Model 167)

A disturbance overshooting suppression function has been added for the Basic PID block (Block Model 011) and Advanced PID block (Block Model

012). Therefore, the influence of disturbance can be suppressed in applications that require high-speed response control, in particular (such as ceramic heater control, flowrate control, and pressure control).

When disturbance overshooting suppression is enabled, the influence of disturbance can be suppressed by setting the characteristics for disturbance (disturbance gain and time constant of disturbance) that enters the control system. Once the error has entered the disturbance stabilization zone (error considered to be stabilized), the disturbance overshooting control function is automatically started if the disturbance width is exceeded.

(changing width exceeding the disturbance stabilization band), and during PD control.

In Control blocks, such as Basic PID, even if the MV reaches the MV upper or lower limit when the MV Limit Alarm Stop Switch turns ON, the MV Upper Limit Flag or MV Lower Limit Flag is disabled and will not be set to ON. (The MV limit will operate, however.).

In Control blocks, such as Basic PID, the MV Error Control Stop Switch turn s ON when an MV error occurs at the MV output value before MV traceback, and the MV is maintained.

The calculation cycle for the Ramped Switch (Block Model 167) can be specified as 0.01 s, 0.02 s, or 0.05 s.

1-1-4 LCB01/05 Version 2.0 Upgrade Information

Simple Memory Card Backup for Function Block Data

Tag Settings, Comments, and User Link Table Connection Data

LCB01/05 Version 2.0 is supported by the easy backup function for data for specified Units and Boards of the CS1-H CPU Unit. The function block data in Loop Control Board RAM can be easily backed up in the same ways as data from Motion Control Units, Position Control Units, and DeviceNet Units.

The simple backup function can back up, recover, and verify all PLC data, including data for Loop Control Boards. This simplifies the task of replacing damaged Boards or making co pies of entire PL C-based proces s control systems.

The tag settings, comments , an d user link tab le conne ction data creat ed using the CX-Process Tool can be b acked up on PLC Memory Card. This means that tag data and other settings do not have to be reset when it is uploaded from PLC Memory Card using the CX-Process Tool.

Back Up Enhanced Segment Program 2 (Block Model 157)

First or Second Refer ence Input Match for Program Start

Note An error occurred with the original function if there was no match. With the

With the previous version of the reference input function, Y1 was output starting from the first set value that matched reference input X1. The enhanced version offers a choice so you can specify whether to start from the first or second set value that matches the reference input.

enhanced function, the progra m can be sta rted from B0 (def ault settin g) when there is no match.

Synchronized Segment Programs

Hot Start Enabled Time Setting

A Segment Program (Block Model 156) was used originally to synchronize time axes when there was mo re than one Seg ment Prog r am and, f o r e xample , it was necessary to us e th e sa me PV start time. The data for time axis outpu t Y2 for one Segment Program had to be written to the time axis output for the other Segment Programs using ITEM write b locks. This took up valuable Segment Program space because each program has only 15 program steps.

The enhanced version of Segment Program 2 (Block Model 157) has a function for synchronizing Segment Programs. With more than one Segment Program 2, you can designate one to be the master to provide a reference time axis and the others to be slaves who follow the master’s time axis. Segment Program 2 slaves do not calculate their own time axis and can be synchronized to the time axis of the Segment Program 2 master. This enables other program settings to be easily synchronized and star ted at the PV start point for one measurement when using programmed temperature settings for multiple zones or progra mmed temperature and pressure settings.

As long as the super capacitor did not discharge, hot starts were performed in the past when the power was turned ON if the power was turned OFF less than 24 hours and hot start was selected as the STAR T mode.

The newly added START mode performs a hot start when the power is turned ON only if it has been OFF for a specified amount of time (specified time for hot start). With this mode selected, a hot start is always performed as long as the power is OFF for less than the specified amount of time (within one hour). This function enables selecting eith er a hot star t or a cold star t depending on how long the power supply has bee n OFF (as long as it has bee n OFF f or less than an hour). If the power is OFF for longer than the specified amount of time, then a cold start is performed when the power is turned ON.

Outline Section 1-1

Secondary Loop AntiReset Wind-up with Cascade Control

Split Converter Block (Block Model 169) Input Range

The PID block on th e primary loop side can be prev e nted from ope rating whe n the high or low MV limit turns ON in the PID block on the secondary loop side during cascade control. This pr events reset wind-up and can be used to prevent the integral actio n from b uilding up in the PID b loc k on the primary side at the high/low MV limits on the PID block on the secondary side.

The only input signal range available for the Split Converter block (Block Model 169) had been −100.00% to 100.00%. This meant that the MV limit for the PID block had to be changed t o ±100.0 0% for heating and cooling control. The Split Conver ter block (Block Model 169) now has another input signal range that can be set from 0.00% to 100.00%.

Field Terminal Blocks I/O field terminal blocks have been added for the following Units.

Wireless Debugging (PV Pseudo-inputs) (Calibration Mode)

MV Tight Shut This function enables tight shut outputs of the values output to the I/O mem-

MV Analog Output Inversion

During Loop Controller operation, pseudo-inputs (fixed values) can be assigned to the PV in Control Blocks (e.g., Basic PID, Advanced PID) from the CX-Process Tool or SCADA Software/Programmable Terminal. This enables easy confirmation of how the Function Blocks operate according to the Control Block PV, even when there is no actual Sensor or other external device connected. If a Sensor error occurs, the Sensor ca n be easily rep laced during operation by assigning pseudo-in puts.

ory of the CPU Unit in the field terminals (analog output terminals) or user link tables. When the output value drops to 0% or lower, the v alue se t as the lo w er

limit (

−20.00% min.) is output, and when the output value rises to 100% or

higher, the value set as the upper limit (115.00% max.) will be output. This function enables 0% or 100% output of the MV from the Contr ol Bloc k to close a valve completely.

This function enables inver ting values output to the I/O memor y of the CPU Unit from the field terminals (analog output terminals) or user link tables. Outputs are inver ted so that an output value of 100.00% is output as 0.00% and an output value of 0.00% is output as 100.00%. Inversion of analog outputs is a simple means of dealing with purchased valves that are found to have a rever sed opening/closing direction.

PID Function Block RUN/STOP

Contact input (RUN/STOP switch) can be used in Basic PID (Block Model

011) or Advanced PID (Block Model 012) to star t or stop PID calculation for

Outline Section 1-1

each function block. The MV at stop setting can also be used to specify the MV when PID calculations are stopped.

Previously, alarm processing and PV input processing was stopped when calculation stopped for each func tion block. With this function, however, PID calculation only is stopped and the quantity specified for the MV is maintained while the calculation can be restarted.

Sequence Table Referencing

Step Ladder Timer Command

User Link Table Pulse Output

Expanded User Link Table EM Specification

Field T erminal Blocks Increased

Evaluation results of the condition rules for a sequence table can be referenced from another sequence table. This enables common processing (as with subroutines) to be compiled in a table for referencing.

A timer can be used in the Step Ladder block (Block Model 301).

In user link tables, when a specified ITEM in a function block starts, a pulse (one-shot pulse) that turns ON only for one refresh cycle can be written to the specified bit address in the CPU Unit’s I/O memory. This enables trigg er signal output processing and other tas ks for the CPU Unit to be performed simply from the Loop Controller.

In user link tables, EM bank numbers 1 to C can be specified as the memor y type to enable user link tables to be used even when EM bank number 0 is being used in ladder programs or file memory functions with functions other than the Loop Controller.

I/O field terminal blocks have been added for the following Units.

For LCB01/03/05 Ver. 3.0 or lat er, the easy backup function backs up the data in flash memory rather than the data in RAM. This means that a verification error will not occur for the backup function even if the data in RAM has been changed by program execution in the Loop Controller. (Previously an error would occur.)

Program data and other d ata can be read from the LCB to the DM Area of the CPU Unit, or written from the DM Area to the LCB, making it easy to quickly replace program data.

program execution: elapsed time since the run/stop command turned ON, program total time, step time output, step remaining time, program time output, and program remaining time.

Data Backup during Loop Controller Operation Added

By using an external backup specification in the System Common block (Block Model 000), function block data can be backed up to Flash memory during Loop Controller operation without using the CX-Process Tool.

Function Block Data Replacement (Direct Recovery) Added

The simple backup function supported by the LCB01, LCB0 3, an d LCB05 has been further improved. Previously, a Memory Card was required both for backup (LCB to Memory Card) and restoration (Memor y Card to LCB). The improved function allows data to be restored using a communications command (FINS command) with no need for a Memory Card. Function blocks in the LCB can thus be overwritten by using communications from a host personal computer.

1-1-8 Basic System Configuration

1,2,3... 1. Unit Having External Interface Functions

The Loop Controller itself does not have external analog I/O and external contact I/O functions. So , it must be used in combinat ion with a Unit having external interface f unctions such as an Analog I/O Unit as show n in the e xample figures in the following pages.

2. CX-Process Tool The Loop Controller itself does not hav e a HMI f or preparing function b lock

data. So, function block data must be prepared on CX-Process Tool, and then downloaded to the Loop Controller for use as shown in the example figures in the following pages.

3. SCADA Software The Loop Controller itself does not hav e a HMI for setting th e Set P oint and

PID constant values , and displa ying the PV. So , the Set Point and PID constant values must be set, and PV monitored using SCADA software or a PT (Programmable Terminal).

Note The Loop Controller uses the Field Terminal block (regardless of the user pro-

gram on the CPU Unit) to read and write areas allocated for contact or analog signals. So, do not perform write operations on the same allocated areas between the Loop Controller and the CPU Unit.

I/O operations can be perfor med internally on the Loop Controller constantly (at each operation cycle) with any specified CPU Unit I/O memory. In this case, the CPU Unit Terminal block or the Expanded CPU Unit Terminal block is used, and the I/O memory address must be specified.

Data exchange is possible with the following I/O memories:

• CIO (channel I/O) Area

• Work Area (W)

• Holding Area (H)

• Data Memory (D)

• Extended Data Memory (E) bank No. 0

Note 1. This function can also be used to designate Units (DeviceNet, Compo-

Bus/S and other Communications Units) on which field terminals are not supported, and CPU Unit I/O memory (remote I/O allocated area, etc.) for enabling I/O.

2. The Loop Controller uses user link tables (regardless of the user program on the CPU Unit) to read and write to specified CPU Unit I/O memory. So, do not perform write operations on the same I/O memor y addresses between the Loop Controller and the CPU Unit.

Data Exchange with SCADA Software

Commercially available SCADA software can also be used to read and write function block data for the Loop Controller. CSV tags can be specified from the SCADA software to read and write ITEM data allocated for the HMI in the CPU Unit’s EM area from control, operation, exter nal controller, and the System Common block. (See note 1. ) The CSV tags are created with the CX-Process Tool.

Note 1. The EM area bank to be allocated for the HMI is specified in the System

2. User Link Table tags can be treated as CSV tags just like the HMI data described above. By specifying these tags, the I/O memory in the CPU Unit can be read and written from the SCADA software.

2) Internal Processing • Prepare a data sheet for the function blocks shown below on CX-Process

Tool, and store the data sheet on the Loop Controller. The function block data sheet describes: (a) software wiring of each function block and (b) parameters in each function block.

• The Loop Controller handles analog I/O signals not in enginee ring units but in percentage units.

Example 1 At analog input, the converted values 0000 to 0FA0 (FF38 to 1068) Hex from

the Analog Input Unit for input 4 to 20 mA (3.2 to 20.8 mA) are converted to

0.00 to 100.00% (−5.00 to 105.00%) before they are processed by the Loop Controller.

Example 2 At analog input, the converted values F830 to 07D0 (F 768 to 089 8) Hex from

the Analog Input Unit for input −10 to +10 mV (−11 to +1 1 V) ar e c onver t ed to

0.00 to 100.00% (−5.00 to 105.00%) before they are processed by the Loop Controller.

Example 3 At analog output, the values 0.00 to 100.00% (−5.00 to 105.00%) are con-

verted to setting values 0000 to 0FA0 (FF38 to 1068) Hex before 4 to 20 mA (3.2 to 20.8 mA) is output from the Analog Output Unit.

Note Converted values (in the case of analog input) f or 0 to 100% on the

Loop Controller and setting v alues (in the case of analog outp ut) for 0 to 100% on the Loop Controller are fixed to the same values as the user ranges. Ho wev er , in the case of I solated-type Analog Input Units (CS1W-PTS01/02/03, PTW01, PDC01, PPS01, PTR01), the Analog Input Unit itself has a range setting f unction. So , an y valu es can be specified as the conver ted values (on condition that the same setting as the range setting is made).

• Likewise, data exchange with the CPU Unit is handled not in engineer ing units but in percentage units. Values in I/O memory words are conver ted to percentage units based upon the specified range before they are input to the Loop Controller. Alternatively, percentage values are converted to Hex values ba sed upon th e specified r ange before they are output to CPU Unit I/O memory.

Example 1 At input from the CPU Unit, the values of 0000 to 0FA0 Hex in the I/O memory

words are converted to 0.00 to 100.00% before they are input to the Loop Controller when the range 0 to 4000 (0000 to 0FA0 Hex) is specified.

Example 2 At output to the CPU Unit, the values of 0.00 to 100.00% are converted to

0000 to 0FA0 Hex before they are ou tp ut to the Cont r ol Un it when the ra ng e 0 to 4000 (0000 to 0FA0 Hex) is specified.

Note 1. In data exchange with the CPU Unit, data can b e actually exchanged within

the range −320.00 to +320.00% and not within the range 0.00 to 100.00%. So, in the above example, the conversion range for 0 to 4000 (0000 to 0F A0 Hex) is 0.00 to +100.00. However, in actual operation, 8300 to FFFF

Outline Section 1-1

Hex and 0000 to 7D00 Hex are converted to −320.00 to −0.01 and 0.00 to +320.00%, respectively, before t hey are processed.

2. Any data range in CPU Unit I/O memor y corresponding to 0 to 100% on the Loop Controller can be specified. (The data r ange is depen dent on the specified input range and output range in the user link table.) CX-Process Tool scales these percentage values to engineering units values, and SCADA software or a PT monitors and sets the values in engineering units. (For details, see 3-1 Configuration of Function Blocks.)

3. The Loop Controller does not process analog da ta in engineering units (scaled values). (All analog data is processed in percentage values.) To monitor/and set analog data in engineering units, the ana log data m ust be scaled on CX-Process Tool and then monitored and set on SCADA software or a PT.

2. Data is refreshed each CPU Unit cycle for the CS1D-CPU@@P.

1. Function Block Operations (independent of and asynchronous with CPU Unit)

The function blocks on the Loop Controller are cyclically executed according to fixed operation cycles. Operations are executed asynchronously with the user program on the CPU Unit.

The operation cycle is one of 0.01, 0.02, 0.05, 0.1, 0.2, 0.5, 1 or 2 seconds (*1), and can be specified to each function block. (The default operation cycle is one second for each function block.) or the LCB05D, cycles of 0.01, 0.02, and 0.05 seconds cannot be set, and for LCB01, LCB03, and LCB05, cycles of 0.01, 0.02, and 0.05 seconds ca nnot be se t for some blocks, i.e., they cannot be set for the System Common block (Block Model 000).

Operation is started when the PLC is turned ON regardless of the CPU Unit operation mode.

*1 The execution cycle for commands in the Step Ladder Program block

(Block Model 301) on the Loop Controller is one of 0.01, 0.02, 0.05, 0.1,

0.2, 0.5, 1 or 2 seconds for each operation cycle in the Step Ladder Program block. This applies to Sequence Table blocks (Block Model 302) as well.

2. External I/O (via the CPU Unit I/O memory)

The Loop Controller actually updates external I/O data from each Unit via CPU Unit I/O memory at each operation cycle of the Field Terminal block.

3. Constant Data Exchange with CPU Unit (by Function bl ock)

The Loop Controller refreshes data I/O with specified CPU Unit I/O memory areas at each operation cycle of the CPU Unit Terminal bloc k or the Expande d CPU Unit Terminal block.

4. On-demand Data Exchange with CPU Unit (b y FINS command issued to Unit)

The CPU Unit can read and write Loop Controller data by issuing the FINS command to the Loop Controller by the CMND (DELIVER COMMAND) command in the Step Ladder Progr am whenever necessary.

5. CPU Unit Status Notification (by ref lecting in System Common b lock)

The status of the CPU Unit (operation mo de, f at al error, etc.) is reflected in the System Common block on the Loop Controller. If necessary, the Loop Controller extracts data from this System Common block.

6. Loop Controller Status Notification (by Auxiliary Area)

The status of the Loop Controller is reflected on the Auxiliary Area in the CPU Unit. Note, however, that this status is reflected every second for LCB01 and LCB05, and not at the I/O refresh cycle. For the LCB05D, this status is reflected each CPU Unit cycle (split refresh).

7. Reading of Error Log Data on Loop Controller

Error log data is stored on the Loop Controller. (The error code, detailed information, date (year/month) and time (hour/minute/second) of occurrence are recorded as one error log data record, and the latest 256 data records are stored.) The time info rmation, including year, month, hour, minutes, and sections, are read from the CPU Unit. Adjust the time in the CPU Unit when necessary. Error log data can be read using the read error log FINS command (command code 2102 Hex).

1-1-12 Internal Mechanism of Loop Controllers

The following describes the internal mechanism of the Loop Controller.

• Function block dat a and error log data are bac ked up by a super capacitor in RAM. During actual operation, the Loop Controller uses the data in RAM.

• Function block data is prepared and downloaded to RAM and flash memory in the Loop Controller from CX-Process Tool running on the computer.

From the CX-Process Tool, you can transfer data between RAM and flash memory whenever necessary.

• Error log data is stored in flash memory can be read using the READ ERROR LOG FINS command (command code 2102 Hex).

• In the default state, function block data is not stored on the Loop Controller. Function block data must be downloaded from a computer to RAM and flash memory in the Loop Controller before the Loop Controller can be run.

Note 1. Function block data in RAM can be back ed up to flash memory using either

of the following methods. a. When downloading LCB01, LCB05, or LCB05D function block data

(i.e., by LCBs), specify LCB backup for the download (i.e., by placing a check mark by “LCB back up indication after download”).

b. Specify backup from the CX-Process Tool software using the Execute

- Backup menu command.

2. Recovering data from flash memor y to RAM is also possible using either of the following methods.

a. Set the power ON startup mode to Cold Start and turn ON the power

supply to the CPU Unit.

b. Specify recovery from the CX-Process Tool software using the Exe-

cute - Recovery me nu command.

3. Specify backup using ITEM 125 (Backup start command while running) of the System Common Block (Block Model 000). During operation of the Loop Controller, the backup will start when ITEM 125 (Backup start command while running) of the System Common Block (Block Model 000) is turned ON.

4. If duplex operation is used with the CS1D-CPU@@P and data in LCB Units is downloaded during operation, operation data will be backed up in the flash memory of only the active Board. The Loop Controller will stop operating at this time. If the power supply is turned OFF before starting operation with either a hot or cold start, the data will exist only in the flash memory of the active Board, so a duplex verification error will occur. If this occurs, check the RDY indicator on the standby Loop Con troller in the CPU Unit to make sure that it is ready to oper ate and then press the initialization switch on the Duplex Unit to initialize duplex operation.

1-2-2 Determining the System Configuration

Check the following points when determining the system configuration:

1,2,3... 1. Number of Analog I/O Points Used on Loop Controller

Which analog signals are input/output on the AI/AO ter minals of the Field Terminal block, and which analog signals are input/output on th e CPU Unit Terminal block or the Expanded CPU Unit Terminal block?

The total number of usable AI/AO terminals on the Field Ter minal block combined with the DO/DI terminals is 80. (For details of the Unit types that can be used, see 1-2-3 Description of Basic System Configuration.)

The maximum number of usable CPU Unit Terminal blocks is 16. (For details of I/O memory area that can be specified, see 3-3-3 Exchanging Da- ta.)

2. Number of Contact I/O Points Used on Loop Controller

Which contact signals are input/output on th e DI/DO t erminals of the Fiel d T e rminal block, and which contact signa ls are input/output on the CPU Unit Terminal block or the Expanded CPU Unit Terminal block?

The total number of DI/DO terminals on the Field Terminal block combine d with the AO/AI terminals is 80 for the LCB01/05, 30 for the CJ1GCPU42/43P, and 40 for the CJ1G-CPU44/45P. (For details of the Unit types that can be used, see 1-2-3 Description of Basic System Configuration.)

The maximum number of usable CPU Unit Ter minal blocks is 2,400. (For details of I/O memory area that can be specified, see 3-3-3 Exchanging Data.)

3. Current Consumption

Is the current consumption of the Units mounted on the rack less than the current consumption of the Power Supply Unit?

Refer to CS1-series Operation Manual (Cat. No. W339), 2-6 Unit Current Consumption.

4. Evaluation of Load Rate

The Loop Controller cyclically processes operation of its own function blocks asynchronously with I/O refreshing of the CPU Unit. The cycle by which operations are processed, or th e “operation cycle,” is dependent on the type and number of function blocks used.

For this reason, when many function blocks whose operation takes a long time to process are used, the actual operation cycle of the entire Loop Controller or an individual function block increases. As a result, the desired preset operation cycle sometimes cannot be satisfied.

The ratio between the actual execution time required for processing operation and the preset operation cycle is called the “load r ate.” The maximum values and current value of each operation cycle group can be confirmed on CX-Process Tool.

A load rate of 80% or less is required in all operation cycle groups on this Loop Controller.

Configuration of Instrumentation System Section 1-2

Note The High Load Alarm Flag (A42408) turns ON if the load rate exceeds 80%

for 6 seconds. If this happens, select the function blocks that can have longer operation cycles and increase their operation cycles. If the load rate is still too high, add on a CPU Unit or a CPU Unit and a Loop Control Unit and dist rib ut e function block processing between the mounted Units.

5. CPU Unit Cycle Time and Minim um Operation Cycle (Pr ocess-control CPU Unit Only)

When the Process-control CPU Unit (CS1D-CPU@@P) is used, the CPU Unit cycle time must be considered in relation to the minimum operation cycle in relation to the load rates outlined above.

a. Effect on CPU Unit Cycle Time

Effect on Normal CPU Unit Cycle Time The following tab le shows the e xtra tim e added to the normal CPU Unit

is further extended. The additional extra time required depends on how the sequence tables are used, as follows:

• Not expanding seque nce tables: +3 ms

• Expanding sequence tables vertically or horizontally: +6 ms

• Expanding sequence tables both vertically and horizontally: +12 ms

The extended cycle time will not be lengthened if the number of e xpanded sequence tables increases, but the number of times that the cycle time is extended will increase.

Configuration of Instrumentation System Section 1-2

b. Restrictions on Minimum Operation Cycle for Loop Co ntroller In-

ternal Function Blocks The operation cycle must be a minimum of 5 times the CPU Unit

cycle time.

When the Process-control CPU Unit (CS1D-CPU@@P) is used, it is desirable to set the longest possible operation cycle to prevent errors in the operation cycle. However, the operation cycle for the internal function blocks of the Loop Controller component in the Process-control CPU Unit must be set to a minimum of 5 times the CPU Unit's normal cycle time. The normal cycle time is the cycle time other than during duplex initialization.

Example: If the CPU Unit cycle time is 40 ms, the minimum operation cycle for the function b loc ks in the Loop Controller componen t must be at least 200 ms (i.e., 200 ms, 500 ms, 1 s, or 2 s.)

If the CPU Unit's normal cycle time is longer than 1/5 the minimum operation cycle for the internal function blocks of the Loop Controller component in the Process-control CPU Unit, th e error in the oper atio n cycle will increase. The error can be an increase of up to one CPU Unit cycle time.

Note If the CPU Unit's normal cycle time is longer than 30% of the mini-

mum operation cycle for the Loop Controller’s internal function blocks for 3 cons ecutive cycles, Auxiliary Area bit A42409 (Operation Cycle Error) will turn ON. Monitor this flag from the CX-Process Tool system operation verification screen and if it turns ON, then set the Loop Controller’s operation cycle to a minimum of 5 times the CPU Unit's normal cycle time.

c. Effect on the Cyc le Time of th e CPU Unit and the O peration Cyc l e

of the Process-contro l CPU Unit ’s Loop Controller during Duplex Initialization

With the Process-control CPU Unit, a maximum of 152 seconds is required for duplex initialization. The CS1D CPU Units and the active Loop Control Board will operate during duplex initialization. The CPU Unit’s cycle time and the Loop Controller’s operation cycle, however, will be temporarily longer than normal. This increase in the cycle time and operation cycle will be the largest during the last cycle time during which duplex initialization is being performed. The increase will be the same for both the cycle time and the operation cycle.

Design the overall system so that no system errors will occur during an extended cycle time and operation cycle. Refer to 3-5 Duplex Opera- tion of Loop Controllers for details on duplex initialization.

d. Details of Extended CPU Unit Cycle Time and Extended Opera-

tion Cycle

• Duplex Initialization (Only in Duplex Mode)

!Caution When using the Process-control CPU Unit (CS1D-CPU@@P), both the CPU

Unit cycle time and the Loop Controller component operation cycle will be temporarily longer than normal during Duplex Initialization (in Duplex Mode). There will be a temporary extension to the cycle time and operation cycle of a maximum of 2.1 s at a maximum of approximately 150 s after the start of duplex initialization. The extended cycle time and operation cycle may temporarily worsen the control characteristics, so verify the system's operation in trial operation before actually running the system.

6. Evaluation of External I/O Response Cyc le (Dependent on CPU Unit's Cycle Time)

The operating speed (operation cycle) itself of each function block on the Loop Controller is not related to the CPU Unit's cycle time. Howe ver , as the CPU Unit's I/O memory is accessed during data exchange, for example, between Analog I/O Units and the Basic I/O Unit, the timing of data exchange is greatly influenced by the CPU Unit's cycle time.

The external analog I/O response cycle (equ ivalent to the I/ O response cycle on a general controller) when the Loop Cont roller is conf igured a s part

Configuration of Instrumentation System Section 1-2

of an instrumentation system is not the same as th e oper at ion cycle of the function blocks; but is a cycle heavily dependent on the CPU Unit's cycle time.

In most cases, the maximum external analog I/O response cycle is as follows depending on the operation timing:

“approximately 2 times the CPU Unit's cycle time” + “approximately twice the operation cycles of the Loop Controller's function blocks”

So, when determining the system con figuration, ca lculate ho w long the e xternal analog I/O response cycle will be within the instrumentation system based upon factors such as the CPU Unit's cycle time and the operation cycles of the Loop Controller's funct ion bloc ks. Also , assess whether or not there will be any prob lems when running applica tions at t he analo g I/O response cycle that you have calculated.

(For details on the rela tionship between the Loop Co ntroller's operation cycles and the CPU Unit's cycle time, see 3-2 Description of Operations. For details on how to calculate the CPU Unit's cycle time , refer to the CS1-se- ries Operation Manual (Cat. No. W339), 15-4 Computing the Cycle Time.)

20.8 mA) are conver ted to 0.00 to 100.00 (-5.00 to 105.00)% before they are

processed by the Loop Controller. These percentage unit values are scaled to engineering units values using

SCADA software.

!WARNING When the Field Ter minal block is used for analog I/O, the unit number set on

the Field Terminal block must match the unit number set on the Analog I/O Unit front panel. Otherwise, input/output (read/write) operations will be performed by mistake on the data of another Special I/O Unit (having the unit number set on the field terminals).

Note 1. With a User Link Table Read (Rd) tag, the word data is interpreted as dec-

imal data and the user can freely specify the range that determines which value is equivalent to 0% and which value is equivalent to 100%. For example, if a range of 0 to 4, 000 (0000 to 0FA0 Hex) is specified for inputs from the CPU Unit, I/O memory word contents between 0000 and 0F A0 will be converted to the range 0.00 to 100.00% and then input.

2. Conversely, with a User Link Table Write (Wr) tag, the user can specify the value to which 0% will be converted and the value to which 100% will be converted. For example, if a range of 0 to 4,000 (0000 to 0FA0 Hex) is specified for outputs to the CPU Unit, outputs in the range 0.00 to 100.00% will be converted to values between 0000 and 0FA0 and then output to I/O memory words in the CPU. In the SCAD A software, t hese percentage units scale the output to the desired industrial units.

Input and Output of Contacts

The Loop Controller can exchange contacts (bit data) with the Basic I/O Unit or the Contact I/O Unit of the Special I/O Unit. In dat a exchange with these Units, use the DI Terminal and DO Terminal blocks on the Field Terminal block having the corresponding number of contact I/O points.
