MOD 30ML Operation

INTRODUCTION

• Serial communications: Instrument Communications Network, RS-232 and RS-485 Modbus standard

• Up to 100 additional discrete remote I/O points through a Remote I/O Interface module

• Logic, advanced and sequential control functions

• Display scripting functions

• Complete configuration control using graphics based blocks and connections

1.2 DESCRIPTION

This microprocessor based 3x6 multiloop controller is designed to meet your process control needs whether you use it for loop indication or to implement advanced process strategies. The controller can display and control continuous process variables such as temperature, pressure, liquid level, or flow and has the ability to perform digital logic functions.

1.2.1 Functionality

The instrument provides continuous control functions such as PID, feedforward, set-point and output tracking, external feedback, set-point and output limiting, in addition to logic and I/O functions. As many as six PID or 4 cascade loops can be run in a single controller with a total loop processing time of 250 milliseconds. Using on-board I/O, PID control loops can be executed as fast as 100 milliseconds.

Using the configuration software for setup, the instrument can run Sequence Blocks based on a drum programmer design with up to 100 inputs, 80 steps and 30 outputs per block; blocks can be cascaded for larger sequences. Sequence Blocks allow forward and backward stepping, unlimited branching and outputs configurable for any data type (discrete, floating point, integer, time, date, ASCII or HEX).

The instrument has 64K of non-volatile RAM which contains the user database and all current process and operating parameters. The optional Portable Memory Module provides 64K of

1-1

Page 8

MOD 30ML Operation

INTRODUCTION

redundant, removable non-volatile RAM which backs up the configured database and, if left on the instrument during operation, current process data. Nonvolatile RAM memory has a typical data retention of 10 years.

1.2.2 Configuration

Configuration of the instrument is accomplished via one of two methods. For applications using single loop PID, single station cascade, feedforward and ratio/bias, canned strategies and their faceplates are easily implemented through the instruments front face displays and operator push buttons. Template configuration uses easy-to-read English prompts.

For more complex applications, beyond those offered with the basic instrument, configuration is accomplished through the icon-based Application Builder Software which is used to create, edit, save, download and document the data base in a graphic environment. Downloading instrument configurations can be done via ICN, or via Modbus over RS-232 or a 4-wire RS485 network. This software is also used to prepare runtime operation files for a computer using the ICN or Modbus protocol. Local display and operations can also be provided using the 2021W Local Control Panel over the ICN.

1.2.3 Operation

The instrument can display and control a variety of process variables such as temperature, pressure, flow, and liquid level. In addition to continuous display of the process variable for a selected loop, the front panel display shows the operating set-point, control output, process alarm indication, loop tag name, and status indication of control mode and set-point source. Front panel keys provide for operational activities such as auto/manual switching, remote/local set-point switching, manual output adjustment, process alarm and diagnostic message acknowledgment, and enabling communication with a host device.

1.2.4 Process I/O

MODBUS

serial communications. Signal conditioning, fail-safe and power fail/recovery parameters may reside in each individual module.

Analog I/O Modules

Analog input modules provide high-resolution signal conditioning performed in the module. Process signals including RTD and thermocouple are connected directly to the rear terminations without requiring transmitters or transducers for signal conversion. A single module supports all thermocouple types with upscale burnout detection. Cold junction compensation is also provided. One current input module type supplies isolated loop power for 2-wire transmitters. Other input types include volt, millivolt, 2- and 3-wire RTD with upscale burnout detection and current input

Two isolated universal analog inputs and two current outputs are standard. Each analog input can receive direct connection of either milliamp (2-wire or non 2-wire), millivolt, volt, RTD thermocouple or resistance. Inputs have full galvanic isolation. Both analog outputs can be user set between span limits of 0 and 50 milliamps.

In addition there can be up to eleven process I/O and communication modules. Plug in modules include various types of analog input, analog output, digital input, digital output, Instrument Communication Network (ICN) and

1-2

Page 9

MOD 30ML Operation

without loop power. The analog output module supplies 4-20mA or 0-20mA. All analog I/O modules are individually, optically isolated to 250Vrms continuous.

Digital I/O

Digital I/O is selected by the user through use of digital I/O modules. Options include both isolated and non-isolated modules. Solid state relay versions offer high isolation voltage capability. Nonisolated modules are compatible with TTL logic levels and provide the ability to interface between similar modules without the need for an external power supply. The Mechanical Relay output module supports Form A, Form B and Form C relays.

Remote I/O (requires Application Builder Software support) Remote I/O input and output modules expand the I/O capability to a total of 100 discrete points. The module communicates over the Remote I/O Network, an RS-485 fieldbus which connects to the instrument via a 2020N RIO module. The RIO module does not need to use a communications position leaving those two positions open for communications modules. Refer to

IB-23C601.

1.2.5 Communications (requires Application Builder Software support)

Two serial communications channels on each instrument allow up to two independent networks to function simultaneously. The first channel is built-in and is selectable for either Instrument Communications Network (ICN), RS-232 Modbus or RS-485 Modbus. The second channel uses an ICN, RS-232 Modbus or RS-485 (2-wire or 4-wire forms) module.

2.1 GENERAL PREPARATIONS

After installation is complete, begin setup by preparing the instrument as follows:

1. Set the SCRV/RUN switch under the front face to the RUN position. If a Memory Module is

present, see Using The Memory Module to load a database stored to a memory module.

2. At ac power source, turn on power to instrument. When power is on, the front panel display illuminates showing either a default database (as shipped from factory) or some other successfully loaded database.

MOD 30ML Operation

SETUP

Default Database

If the instrument does not have a valid user database, the first DEVICE display (device status entry point) will appear and any diagnostic indications will be enabled. The default device tag is TEMP 100.

The device display shows the state of the instrument on line 3 (see Device States).

The keys labeled NXT (next step) and PRV (previous step) move you through the entry points for the setup tables while the down arrow ∇ indicates the down arrow key can be used to enter a step the instrument state is RUN, the TAG key will switch you to the first user runtime display.

Valid User Database Loaded

If the instrument has a valid user database, the power up display (Device, Previous or User) will appear and any enabled diagnostics, such as for power up and power down, will be indicated. You can prepare the instrument for setup by acknowledging these diagnostics and making any necessary adjustments to your operating conditions from the user display (see Operation for general operation).

Return to the DEVICE display by pressing and holding the TAG key.

alarm and repeat until the end where you can return to the device display (see Alarms in Section 3.13).

2.2 DEVICE STATES

The instrument state is indicated by a three letter code on line 3 of the device displays. Except for Local Hold, installation of a template will change the instrument state to Run.

DEF The Default state means the instrument has no valid user database and is running an

internal database to maintain communications and system activities.

HLD The Hold state indicates the instrument has a valid user database and is performing

overhead functions only - no loops are running.

LHD The Local Hold state indicates the SCRV/RUN switch is in SCRV and the instrument

is in the Local Hold state.

RUN The Run state means the instrument has a valid user database and is running that

database.

2.3 USING THE MEMORY MODULE

The backup memory module is used to maintain a mirror image of the 64K instrument database. A small part of this image is reserved for shutdown information and serves as a valuable diagnostic tool. The module may be write protected to protect shutdown and other information.

2.3.1 DOWNLOAD From Memory Module to Main Database

Follow this procedure to load a database stored in a memory module.

1. Set Memory Module switches to "read/write" or "Read Only" and "Normal".

2. Power up the instrument.

The instrument automatically attempts a download from the memory module during

power-up. If the module database is 'good' (configured, version compatible, has valid checksums, no ICN or comm port mismatch), the 'download on warm start' attribute is YES and the instrument did not have a previous shutdown fault, the transfer will occur. The download on warm start attribute allows a user to (for instance) write protect a module with cold start values in it and have it download only on cold start.

2-2

Page 13

2.3.2 UPLOAD From Main Database to Memory Module

Follow this procedure to store a database to a memory module.

1. Set Memory Module switches to "read/write" and "module load".

2. Power up the instrument.

3. UPLOAD? is displayed by the instrument. To upload to the memory module, press either the up or down arrows and press the key labeled ENT for enter. The default database is run with instrument state equal to UPLOAD.

4. UPL DONE SET WP? is displayed by the instrument. The module is now loaded with the instrument database. If you want to write protect the module, select YES and enter (UPL DONE, WP DONE). Skip this command and go to the next step if you do not want to write protect the module.

5. Power down the instrument. Instrument state cannot be changed until power is removed and module switch is placed in "Normal".

6. Set Memory Module switches to "read/write" or "Read Only" and "Normal".

7. Power up the instrument.

2.5 TEMPLATE SETUP

The general procedure for working with a new template configuration is to load defaults, edit system parameters, edit first user compound, insert any new user compounds and then edit them. After configuring compounds for single loop PID or Master Slave Cascade control, you then install the database.

* NOTE INSERT places a new compound in the list AFTER the current compound.

DELETE deletes the current compound. The System compound cannot be deleted.

3.1 INTRODUCTION

NOTE: The operating information and instructions in this section apply to

instruments which have been configured using the template setup procedure described in Section 2.

All operator activities related to ongoing operations are performed using a series of runtime displays which are accessible on the instrument front panel. A series of tuning displays can be accessed from the runtime mode. These displays allow tuning adjustment for numerous alarm and control parameters. Tuning access can be password protected.

Operator activities available in the runtime mode include:

MOD 30ML Multiloop Controller

OPERATION

• Selecting of the control loop requiring operator activity

• Monitoring process variable input and set-point

• Monitoring output to the control device

• Monitoring alarm status

• Viewing alarm displays and acknowledging alarms

• Changing the local set-point

• Changing operating mode between manual and automatic

• Changing output value while in manual mode

• Changing set-point source between local set-point and remote set-point (if enabled)

• Changing ratio and bias values (if configured)

3.2 FRONT PANEL

The front panel has three 8-character engineering displays, three 3-character status displays, and three 50-segment bar graphs. Figure 3-1 shows the instrument front panel.

OPERATION

3.7 UP / DOWN KEY OPERATION

3.7.1 Ramping

The Up (∆) and Down (∇) keys are used to ramp variables such as local set-point and control output up or down. The ramping function also applies to tuning and setup. Various ramp rates can be obtained by using the ∆/∇ keys alone and in combination with the ‘A' and ‘R/L' keys. The available ramping options are as follows:

Increment Least Significant Digit

Ramp Least Significant Digit

Increase Ramp Rate

Decrease Ramp Rate

Exit Ramping Function

Press and release the ∆ or ∇ key.

Press and Hold an ∆ or ∇ key (ramp rate is about two changes per second).

Press the ‘A' key while [FST] is flashing. Each depression of the [FST] key moves the ramping digit one place to the left.

Press the ‘R/L' key while [SLO] is flashing. Each depression of the [SLO] key moves the ramping digit one place to the right.

Press the TAG key to exit prior to time out of the flashing [FST] and [SLO] displays.

3.7.2 Data Entry

There are two modes by which the new value or state becomes active in a loop; Immediate Entry and Procedural Entry:

Immediate Entry

[∇ / ∆]

Procedural Entry

[∇ ∆]

The new value of the variable being changed is immediately

implemented in the loop displayed on the front panel. The immediate entry mode is indicated by a slash mark between the arrow icons [∇ / ∆]. Examples of immediate entry variables are local set-point and control output when the loop is in manual. State changes are not allowed in the immediate entry mode.

The new value of the variable or state being changed is not implemented in the loop until an entry procedure is performed. After obtaining the required value using the up or down keys, the new value is entered by pressing the R/L key while an [ENT] display is flashing next to the key. The procedural entry mode is indicated by the absence of a slash mark between the arrow icons [∇ ∆]. Examples of procedural entry variables are gain and reset; examples of state changes are direct to reverse control action and suppressing an enabled alarm. In the procedural entry mode, the flashing entry prompt [ENT] times out 10 seconds after use of the arrow keys stops. Thus there is a timed window during which a new value can be entered. If the R/L key is not pressed in time, the new data value is aborted and the variable or state returns to its previous value.

3-8

Page 41

3.8 SELECTING A CONTROL LOOP FOR DISPLAY

The instrument can contain as many as eight control loops. Each loop is identified by a user configured tag name. The data displayed on the front panel applies only to the loop which is identified by the tag name shown on the Line 1 Display.

Press the TAG key to switch the display from one loop to another. Pressing the key repeatedly while in any runtime display steps the display through the configured loops. Holding down the TAG key exits the runtime display and accesses the device displays. On the last loop display, pressing the TAG key wraps back to the first loop allowing the sequence to be repeated. An example of a runtime display for two different loops is shown below.

Tag name indicates that this front panel display applies to flow control loop FIC-211.

OPERATION

3.9.3 Single Loop Automatic Operation with Ratio and Bias

A set-point bumpless transfer is possible when AUTO RAT (ratio) or AUTO BIA (Bias) is configured. These configurations calculate a ratio or bias value that balances the remote setpoint with the local set-point upon a switch from local to remote set-point.

Using Auto Bias, a switch from local to remote set-point will cause the bias value to automatically adjust to the difference between the active set-point and the remote set-point times the ratio value. For example, if the active set-point is 17.00 and the remote set-point is 20.00 with a ratio of 2.00, then the auto bias value will be:

-23.00 = 17-(20*2).

Using Auto Ratio, a switch from local to remote set-point will cause the ratio value to automatically adjust to the ratio between the active set-point minus bias and the remote set-point. For example, if the active set-point is 17.00 and the remote setpoint is 20.00 with a bias of -23.00, then the auto ratio value will be: 2 = 17- (-23.00)/20.

From the Auto, Local, Bias display, press the R/L key to switch from local to remote set-point (REM).

Bias value automatically adjusts to balance remote and local set-points.

Press the ∆ or ∇ key to adjust the bias value and change the active remote set-point by the bias value.

Press the scroll key until appears SP to view the new set-point.

The same idea applies to use of ratio.

3.9.4 Single Loop Automatic Operation with Feedforward

Feedforward control is a strategy used to compensate for disturbances in a system before they affect the controlled process variable. A feedforward control system measures a disturbance variable, predicts its effect on the process, and applies corrective action to cancel the effect of the disturbance. A block diagram of this type of system is shown below.

MOD 30ML Multiloop Controller

OPERATION

This system provides a combination of feedforward and feedback control. Feedback provides its normal function of holding the process at the set-point. Feedforward helps the feedback function by modifying the control output as required to cancel the effect of variations in the disturbance variable. The feedforward input (set up as a percent of output) is multiplied by a constant (gain), and a bias value (%) is added to or subtracted from the signal. The gain and bias values are tunable. The feedforward function can be configured to either add the signal to the control output or multiply the output by the signal.

The front panel display and control key operations for feedforward control resemble the example below.

[AUT] indicates that the controller is in automatic with feedforward input.

[LOC] indicates local set-point.

Page 47

MOD 30ML Multiloop Controller

OPERATION

Transfers In A Loop with Automatic Reset

When the control algorithm has reset (integral) response, transfers from automatic to manual and from manual to automatic are always bumpless. After switching from manual to automatic, the process variable is under automatic control in response to the active set-point, either local or remote.

If the control loop is configured for local set-point tracking, the local set-point tracks the process value when the loop is in manual. The process is always at the local set-point when a transfer to automatic is made, regardless of set-point limits

If the control loop does not have local set-point tracking, the local set-point and the process variable may not be at the same value at the time of a transfer from manual to automatic. The transfer is still bumpless, but immediately after the transfer the process ramps toward the local set-point value at the reset rate.

Transfers In A Loop with Manual Reset

If the control loop does not have automatic reset (integral) response, any set-point/process offset at the time of a transfer from manual to automatic is maintained. If the loop is configured to provide procedureless manual reset, the manual reset value required to eliminate the offset is automatically calculated while the loop is in manual, and this calculated value is used to remove the offset following a transfer to automatic.

If the loop does not have procedureless manual reset, a set-point/process offset after transfer to automatic can be eliminated by adjusting the manual reset value. This value is one of the tunable parameters available for adjustment in the tune sequence. Access the tuning sequence and adjust manual reset to the required value as described in Section 3.14 Tuning.

3.12 CASCADE OPERATION

A cascade control system is a multiple-loop system where the primary variable (in the master controller) is controlled by adjusting the set-point of a related secondary variable (in the slave controller). The secondary variable then effects the primary variable through the process. A block diagram of this type of cascade system is shown below.

The main objective in cascade control is to divide an otherwise difficult to control process into two portions, whereby a secondary control loop is formed around a major disturbance, thus leaving only minor disturbances to be controlled by the primary controller.

MOD 30ML Multiloop Controller

OPERATION

3.12.1 Cascade Operation in Manual

While in manual [MAN], the slave set-point tracks (automatically remains equal to) the slave process variable. This characteristic is optional by enabling set-point tracking on the slave. It will eliminate the need for the controller to respond immediately to any deviation which exists when the mode is changed from manual to automatic. Without set-point tracking on the slave, the controller responds to the deviation which exists by ramping the output at the reset rate established when the instrument was tuned.

Master Controller

Slave set-point tracks slave process variable.

Master output tracks slave set-point.

Slave output can be adjusted manually.

Master set-point tracks master process variable.

Slave Controller

Meanwhile, the output of the master controller tracks a signal from the slave controller which represents the set-point of the slave automatically adjusted for ratio or bias. The requirement for balancing the local and remote set-point signals prior to placing the slave controller in cascade mode is eliminated.

3-17

Page 50

MOD 30ML Multiloop Controller

OPERATION

It may also be desirable for the set-point of the master to track the master process variable. This depends on the desirability of permitting the set-point of the master to vary indirectly in response to changes at the slave controller.

3.12.2 Cascade Operation in Auto

Since the control element (valve, air damper, etc.) is directly manipulated by the slave, the cascade master is configured to permit only auto mode which simplifies operations by ensuring that all mode transfers and manual intervention can be accomplished exclusively at the slave.

Remote slave setpoint tracks master output.

3.13 ALARMS

Alarm conditions are indicated on the front panel visually by an alarm light and audibly by a beeper. Various combinations of audible and visual alarm indication can be obtained by configuration. Alarm data can be viewed on a dedicated alarm display provided for each active alarm.

Alarms can be configured for each control loop to respond to an alarm condition on the process variable, the control output, and the deviation between the set-point and process values. As many as four process alarms and two each of the deviation and output alarms can be configured for each control loop. Alarm types can be high, high high, low, low low, and a digital output can be enabled for each alarm. The parameters of any of these alarms can be adjusted in the Tune mode. Tuning allows the following:

• Adjustment of trip value

• Adjustment of hysteresis value

• Assignment of a priority

• Suppression of a configured alarm

Other alarms are available as follows:

MOD 30ML Multiloop Controller

OPERATION

• The instrument provides an alarm indication for all diagnostic events which occur in each configured control loop. Parameters of these alarms are not tunable.

• Data quality alarms can be configured to provide an indication of bad quality on the process, remote set-point, and feed forward inputs. Priority is the only tunable parameter for quality alarms.

3.13.1 Alarm Trip points

The high and low alarm trip-points for each control loop are determined at the time of setup. The trip points and other parameters can be adjusted in the tune mode (see Section 3.14 Tuning). Process and deviation alarms are triggered by the process input. A process alarm trips (becomes active) when the process reaches a preset high or low trip-point. A deviation alarm trips when the process value deviates from the control loop set-point by a preset amount. An output alarm is activated when the control loop output reaches a preset high or low trip-point. Alarms resulting from rising values are defined as high, and those resulting from falling values are defined as low. The terms high high and low low mean that two separate alarms are configured on a single variable with either two high or two low trip points.

3.13.2 Alarm Priority

A priority (0 to 255) can be assigned to each alarm. Alarm priorities are used to display a more important alarm before a less important alarm when viewing the alarm displays. Priority 1 is the highest priority and priority 255 is the lowest. Priority 0 is assigned to alarms which do not require acknowledgement; these alarms can only have an active or clear condition.

3-19

OPERATION

3.13.3 Monitoring and Acknowledging Alarms

A dedicated alarm display provides data on each unacknowledged and active alarm. There are six types of alarm displays (An example of each display type is shown on the following pages):

• Input variable displays (Process, Remote Set-point, Feed Forward)

• Control output displays

• Set/Process deviation displays

• Data quality displays

• Combination of data quality and input variable displays

• Diagnostic displays

The operator is alerted to an alarm condition by the alarm light in the upper right hand corner of the front panel.

Depending on instrument configuration, the light can flash or turn on steady at the inception of an alarm condition, and a beeper can provide audible indication that an alarm is present. To view alarm data and acknowledge alarm conditions proceed as follows:

1. When the alarm light or beeper indicates an alarm condition, press the alarm scroll key to access the alarm displays. Pressing the key repeatedly scrolls through a series of displays covering all unacknowledged alarms and all acknowledged alarms which are active (alarm condition still present). See Section 3.13.4 for the viewing sequence of the alarm displays.

2. Press the ‘A' key to acknowledge an unacknowledged alarm. Refer to the examples for acknowledgement details.

3. Press the alarm key to advance to the next alarm display, then view the data and acknowledge the alarm as required.

4. If it is necessary to return to runtime prior to viewing all the alarms, press the R/L key [RET] to immediately return to runtime.

5. Continue scrolling through alarm displays until [ALARM ] [END] appears on lines 1 and 2, then proceed as follows:

3.13.4 Alarm Display Viewing Sequence

When the alarm scroll key is pressed to initiate viewing of the alarm displays, the sequence in which the displays appear depends on the instrument state, type of alarm, alarm priority, and whether the alarm has been acknowledged.

Instrument In Run State

When the state is RUN the viewing sequence is:

1. Unacknowledged diagnostics in the order of their location in the data base.

2. Unacknowledged quality alarms in order of highest priority to lowest priority (priority number 1 - 255).

3. Unacknowledged process alarms in order of highest priority to lowest priority (priority number 1 - 255).

4. Any active, quality alarms not viewed in Step 2 in the order of highest priority to lowest priority (priority 0 - 255).

NOTE: Priority 0 alarm displays appear only in Steps 4 and 5 because 0 priority

does not have an unacknowledged condition.

5. Any active process alarms not viewed in Step 3 in order of highest priority to lowest priority (priority number 0 - 255).

6. Active, but already acknowledged, diagnostics in the order of their location in the data base.

7. When the above sequence has been completed the [ALARM] [END] display appears, and pressing the R/L [RET] key returns the runtime display that was visible before entering the viewing sequence.

Instrument Not In Run State

When the state is not RUN the viewing sequence is:

1. Unacknowledged diagnostics in the order they are in the database.

2. Active, but already acknowledged, diagnostics in the order they are in the database.

3. When the above sequence has been completed the [ALARM] [END] display appears, and pressing the R/L [RET] key returns the runtime display that was visible before entering the viewing sequence.

Alarm Activity During A Viewing Sequence

After viewing of the unacknowledged diagnostic alarm displays is started, any new diagnostic that is stored in the data base area that has already been searched is not displayed until the next viewing sequence. After viewing of the unacknowledged process alarm displays is started, any new process alarm which becomes active is not displayed until the next viewing sequence.

3.14 TUNING

A series of tuning displays can be accessed directly from the runtime displays. These displays provide for tuning of both alarm and control parameters. Progression through the tuning displays, and tuning of parameter values is done using the front panel keys. Specific parameters available for tuning depend on the configuration of the template identified by the loop tag. Access to tuning adjustments can be password protected.

3.14.1 Password

When a tune password is configured, the assigned password number must be entered in order to make tuning adjustments. A single password permits access to both alarm and control tuning adjustments. If the requested password is not entered or the entered password is not correct, the tuning parameters and their current values can be viewed but the values cannot be changed.

The password access can be configured to timeout after an elapsed time of 1 to 54 minute s. After initial entry of the password, you can exit the tune sequence and reenter without using the password until the end of the timeout period. If the timeout occurs during a tuning operation, the sequence can be completed. Reentry will again require the password. If the timeout is set to 0, the timeout period is infinite. In this case the password is required for initial entry to the tune sequence and is never used again.

3.15 STARTUP

Procedures may vary from application to application, depending upon individual requirements and control loop setup. The initial operating mode (usually manual), the set-point source (usually local), set-point value, and control output can be configured for specified safe values when power is first applied to the instrument. Each time a control application is first started up, check all these items before turn-on.

3.15.1 Startup Without Set-Point Tracking

To start up a control loop in the manual mode:

1. Select the required loop using the TAG key.

2. Place the loop in manual mode with local set-point.

3. Adjust local set-point to starting value required for process variable.

4. Adjust manual output to a safe starting value for the process. This is usually below 0% or

above 100% of span.

5. Open block valve ahead of control valve or perform any other procedure required to

make the process variable available, such as starting a pump, turning on a power supply, etc.

6. Manually adjust control output to bring process variable to set-point value. Ramping the

output should be slow enough to allow the process to respond to the change without overshooting the set-point. Process is now operating under manual control with process at the set-point.

3.15.2 Startup With Set-Point Tracking

The startup procedure is simplified when set-point tracking is used. With the control loop in the manual mode, the set-point tracks the process so that the process and set-point values are together when the operator switches to the automatic mode.

To start up the controller with set-point tracking:

1. Select the required loop using the TAG key.

2. Place the loop in manual mode.

3. Adjust manual output to a safe starting value for the process. This is usually below 0% or

above 100% of span.

4. Open block valve ahead of control valve or perform any other procedure required to

make the process variable available, such as starting a pump, turning on a power supply, etc.

5. Manually adjust control output to bring process variable to required value. Ramping the output should be slow enough to allow the process to respond without overshooting the required control point.

An alternate procedure in Step 5 is to bring the process variable up part way, to see that the control application responds in a controllable manner, then switch to the automatic mode early in the startup and bring the process variable up to the operating point under automatic control by adjusting the set-point.

IF 16 COMMUNICATIONS PORT MISMATCH One of the following conditions was detected:

• An ICN module (2030N)is installed but no

matching ICN block was found in the user

database. Matching includes slot numbers and

the module address switch setting, if not 'ANY'

in the ICN block.

• An RS-232 module (2033N) or an RS-485

module (2034N) is installed but no matching

MSC block was found in the user database.

Matching includes slot numbers/module type

and the module address switch setting unless

'ANY' is configured in the MSC block

IF 17 INSTRUMENT SHUTDOWN FAULT When the instrument was last powered, an

event occurred which caused it to shut down. It

is now locked in the DEFAULT state. The user

should investigate the cause of the shutdown

and try running the instrument again, if desired,

by writing ACK SHUTDOWN FAULT (value 1)

to IF block Attribute No. 141, Command (CMD).

This acknowledges that the user has seen the

information relating to a previous shutdown

fault and reinitializes the SHUTDOWN INFO

area. Until this is done, the instrument will not

accept commands which could cause it to leave

the DEFAULT state. Information preserved at

shutdown is stored in the non checksummed

save area in the battery backed up RAM and is

examined through the configurator STATUS

display activity.

IF 18 MODULE SHUTDOWN FAULT When the memory module was last used, the

instrument on which it was installed suffered a

shutdown fault. The shutdown information

preserved in the module is stored in volatile

RAM and is examined through the configurator

STATUS display activity. The battery backed

up RAM must be write protected (switch set at

READ ONLY) to prevent this data from being

overwritten when powered up for examination

on another instrument.

IF 19 PROCESSOR WATCHDOG FAULT When the instrument was last powered, the

processor got 'lost' and the watchdog timer shut

the instrument down. See Code 17,

INSTRUMENT SHUTDOWN FAULT.

IF 20 SPURIOUS EVENT FAULT When the instrument was last powered, the

processor was interrupted by an unexpected

event (i.e. it had no handler to respond to the

event) and the instrument therefore shut down.

the RAM chips failed the read/write test, and the instrument therefore shut down. The error address is preserved at shutdown. See Code 17, INSTRUMENT SHUTDOWN FAULT.

IF 23 I/O BOARD 1 COMMUNICATIONS

ERROR

An error (no response or bad message checksum) occurred in trying to communicate with the carrier board. There are wrap around counters for these errors at IF1,SLNORSPS and IF1,SLCHKSMS.

IF 39 BAD CLOCK CHIP The real time clock chip is not working

correctly. Time and date information will not remain current through a power outage.

IF 40 TIME AND DATE NOT VALID The time of day, calendar date, and day of

week need to be set.

IF 41 I/O IS LOCKED The I/O is locked because Attribute No.195,

Lock I/O Blocks (IOLOCK) is YES. In the locked state, output function block values are not copied to the output module block output value, and input module block values are not copied to the input function blocks. Field input values continue to be updated in the input module blocks and output module block values can be written by the operator.

IF 42 COMMUNICATION BLOCKS ARE

LOCKED

Communications are locked because Attribute No. 158, Lock ICN Communications Blocks ? (COMMLOCK) is YES. In the locked state, the output communication blocks do not fetch data from their source pointers (they do continue to send out their current value), and input communication blocks do not refresh their outputs from received messages. Input and output communication block outputs can be written to by the operator.

IF 43 DMA FAULT An error occurred in a DMA transfer and the

instrument therefore shut itself down. The diagnostic is readable when the instrument is powered up again. See Code 17, INSTRUMENT SHUTDOWN FAULT .
