Notation in this Manual
This manual uses the following notation.
• “Loop Controller” is used as a generic term to refer to the Loop Controllers in
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 refer to the Loop Controller functional element. The Loop Controller function element in a CJ1G-CPU44P
Loop-control CPU Unit is the LCB03, so “LCB03” is used to refer to the Loop
Controller functional element.
• Model numbers are used to refer to specific Loop Controller models.
In the CX-Process Tool Operation Manual for version 3.2 or earlier, functional
element names (LCB) are given as “Loop Control Board.” In the CX-ProcessTool Operation Manual for version 4.0 or higher, simply “LCB” is used.

PRECAUTIONS
This section provides general precautions for using the CX-Process Tool, CS/CJ-series Programmable Controllers (PLCs),
and related devices.
The information contained in this section is important for the safe and reliable application of Programmable Controllers. You must read this section and understand the information contained before attempting to set up or operate a
PLC system.
This manual is intended for the following personnel, who must also have knowledge of electrical systems (an electrical engineer or the equivalent) and instrumentation systems (a process engineer or the equivalent).
• Personnel in charge of installing FA systems.
• Personnel in charge of designing FA systems.
• Personnel in charge of managing FA systems and facilities.
2General Precautions
The user must operate the product according to the performance specifications
described in the operation manuals.
Before using the product under conditions which are not described in the manual
or applying the product to nuclear control systems, railroad systems, aviation
systems, vehicles, combustion systems, medical equipment, amusement machines, safety equipment, petrochemical plants, and other systems, machines,
and equipment that may have a serious influence on lives and property if used
improperly, consult your OMRON representative.
Make sure that the ratings and performance characteristics of the product are
sufficient for the systems, machines, and equipment, and be sure to provide the
systems, machines, and equipment with double safety mechanisms.
This manual provides information for programming and operating the Loop Controller. Be sure to read this manual before attempting to use the Loop Controller
and keep this manual close at hand for reference during operation.
3Safety Precautions
WARNING It is extremely important that a PLC and all PLC Units/Boards be used for the
!
specified purpose and under the specified conditions, especially in applications
that can directly or indirectly affect human life. You must consult with your
OMRON representative before applying a PLC System to the above-mentioned
applications.
3Safety Precautions
WARNING Check the following items before starting to run the LCB:
!
• Do not allow the bank of the EM Area with the number specified for allocation to
the HMI (human-machine interface) data to be used by the CPU Unit or other
Units for any other purpose. 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. If areas overlap, the system may operate in an unexpected
fashion, which may result in injury.
• Do not allow the area to which user link table data is written to be used by the
CPU Unit or other Units for any other purpose. If areas overlap, the system
may operate in an unexpected fashion, which may result in injury.
• Analog Input/Output Units used in combination with the LCB 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 (i.e., the one whose unit number is set on the
Field Terminal block).
• The defaults of the System Common block on the LCB must be set correct-
ly.
xxiv
WARNING Check the following items before starting Loop Controller operation:
!
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 overlap, 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 memory 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 I/O Units used in combination with the Loop Controller must be mounted
correctly.
The unit number set on the front panel of the Analog I/O Unit must be the same
as the unit number set on the Field Terminal Function Block. If the unit numbers
are not the same, I/O (read/write) will be performed on the data for another Special I/O Unit (i.e., the one whose unit number is set in the Field Terminal Function
Block).
The initial settings of the System Common Block in the Loop Controller must be
set correctly. In particular, make sure that words in the Data Memory used for the
Node Terminals in the CPU Unit controlling the Loop Controller are not used for
other applications on the PLC.
When writing data to the I/O memory in the CPU Unit with function blocks (e.g.,
using Send All Blocks, Expanded DO/AO Terminal to CPU Unit, or DO/AO Terminal to CPU Unit), be sure that the words written to in I/O memory are not being
used for any other purpose. If I/O memory words are allocated to more than one
purpose, the PLC system may act unexpectedly and cause injury.
3Safety Precautions
WARNING Always stop the operation of the LCB before converting any of the EM Area
!
to file memory. If any part of the EM Area that is being used by the LCB for
the HMI is converted to file memory during Board operation, the system may
operate in an unexpected fashion, which may result in injury.
WARNING Do not perform processing in such a way that the Loop Controller and CPU Unit
!
write to identical I/O memory words allocated to a contact output or analog
output of an external Unit. If the same words are written to, the externally
connected loads may act unexpectedly and cause injury.
WARNING When the calibration function is executed, the MV (manipulated variable) will

change due to changes in the PVs (present values) input to the control block.
Therefore, set pseudo-input values to confirm safety when the MW changes
before executing the calibration function. Devices may perform unexpected
operations, resulting in serious accidents.
CautionBefore transferring function block data (initial setting data or operation data) to
!
the Loop Controller, confirm that the destination for the data is correct and also
confirm the overall safety of the system (including the Loop Controller). Not doing so may result in unexpected operation.
CautionBefore performing Validate Action, be sure to perform Compare on currently
!
opened function files and the Loop Controller’s function block data. If there are
inconsistencies in the registered function blocks (block address vs. block model), it will not be possible to perform Validate Action correctly.
xxv
Before forcing changes of analog signals or contact signals using Validate Action, confirm the safety of the instrumentation system as a whole. Not doing so
may result in unexpected operation.
CautionWhen downloading a sequence table for the LCB (unit ver. 1.5 or later) 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.
CautionConfirm in advance the conditions at any node for which the sequence table is
!
being edited over a Controller Link or Ethernet network. Not doing so may result
in unexpected operation.
CautionConfirm the status of connected devices before transferring the setting for the
!
MV tight shut function and MV analog output reverse function to the Loop Controller. Devices and equipment may perform unexpected operations if the data
destination is mistaken.
CautionWhen the calibration function is executed, the MV (manipulated variable) will
!
change due to changes in the PVs (present values) input to the control block.
Therefore, set pseudo-input values to confirm safety when the MW changes before executing the calibration function. Devices may perform unexpected operations, resulting in serious accidents.
4Application Precautions
4Application Precautions
Observe the following precautions when using CX-Process Tool and Loop Controller.
CautionIf 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. (For LCB only)
CautionLoop Control Unit data is monitored and operated using CX-Process Monitor or
!
CX-Process Monitor Plus based on the monitor tag files created using CX-Process Tool. When creating monitor tag files using CX-Process Tool, CX-Process
Monitor must be installed on the same computer.
CautionBefore using function block data in actual operation, confirm operation by moni-
!
toring run status (to check the load rate; select Execute/Operation/Monitor
Run Status) and validating actions (select Validate Action/Start) with CX-Pro-
cess Tool. In particular, be sure to confirm that the load rate will be less than 60%.
(For details on the load rate, refer to the Operation Manual for the Loop Controller.)
xxvi
CautionWhen uploading the Loop Controller’s function block data, observe the following
!
precautions.
When performing Upload New for Loop Control Units of version 1.5 or earlier,
data on the Edit Block Diagram Screen (function block information) will be lost,
and the block diagram showing the connections between function blocks will not
be displayed.
When performing Upload Previous, if the data in the source file currently
opened using the CX-Process Tool and the Loop Controller’s function block data
does not match the registered function blocks or the data on the Edit Block Diagram Screen, the data currently opened may change to illegal data.
CautionThe Loop Controller can read and write I/O memory in the CPU Unit using the
!
Field Terminal Function Blocks or CPU Terminal Blocks independent of the user
program (Step Ladder Program) in the CPU Unit. Do not write to the same I/O
memory words from both the Loop Controller and the CPU Unit.
CautionTo hold an analog output or contact output at a specific value (for example, the
!
maximum value or minimum value) when the Loop Controller stops running,
create a Step Ladder Program in the CPU Unit so that the corresponding output
bit allocated to Analog Output Unit or Contact Output Unit is set to the desired
value using an NC condition of the Loop Controller Running Flag (bit 00 in allocated CIO word “n”) as an input condition.
4Application Precautions
CautionIf a fatal error occurs in the CPU Unit (including fatal errors created by execution
!
of a FALS instruction), the Loop Controller will also stop running. To hold analog
outputs to the previous values before the stop occurred, and to set analog outputs to either the minimum value or maximum value, use the output hold function
of the Analog Output Unit or Analog I/O Unit.
CautionBefore 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 when the power to the PLC is turned ON regardless of the operating mode
of the CPU Unit (including in the PROGRAM mode). (Internally, the analog output values and contact outputs are sent from the CPU Unit to Basic I/O Units and
Analog Output Units.)
CautionFail-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 interruptions, or other causes.
CautionConfirm that no adverse effect will occur in the system before attempting any of
!
the following:
• Changing the operating mode of the PLC (including the setting of the startup
operating mode).
• Force-setting/force-resetting any bit in memory
• Changing the present value or any set value in memory
CautionBe sure that all mounting screws, terminal screws, and cable connector screws
!
are tightened to the torque specified in the user manuals. Incorrect tightening
torque may result in malfunction.
xxvii
CautionIn the event of system or power failure, CX-Process function files (extension
!
“.ist”) may not be saved. It is recommended that function files are saved regularly.
CautionDo 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 NTAL001 RS-232C/RS-422A Adapter. Doing so may damage the external device
or CPU Unit.
