2.3 Auto/Manual Station (Templates 3 and 4)

Note. Refer also to Appendix A2.1 – Series and Parallel Operation.

The auto/manual station provides a backup for a master controller. In normal operation the COMMANDER 500’s analog output follows the master controller’s output value. A fault in the master system can be identified either by detecting a low signal on the master output (template 3) or via a digital signal (template 4). When a fault is detected the COMMANDER 500 goes into manual mode with its output either set to the last valid master output value or to a configured output value – see Section 4.6, Control Configuration/ Configured Output 1. When the master output is restored or the digital input returns to its inactive state, the COMMANDER 500 switches back to auto mode.

Note. The Alarm A1 Trip value must be set when using template 3.

2.4 Analog Backup (Templates 5 and 6)

Note. Refer also to Appendix A2.1 – Series and Parallel Operation.

The analog backup station provides a backup for a master controller. In normal operation (remote control mode selected) the COMMANDER 500’s current output follows the master controller’s output value. A fault in the master system can be identified either by detecting a low signal on the master output (template 5) or via a digital signal (template 6). When a fault is detected the COMMANDER 500 switches into local control mode and the process is controlled by the PID output of the COMMANDER 500. The COMMANDER 500 PID algorithm tracks the master output value continuously in order to ensure bumpless transfer from remote to local mode operation. When the master output is restored or the digital input returns to its inactive state, the COMMANDER 500 switches back to remote control mode.

Note. The Alarm A1 Trip value must be set when using template 5.

2.13 Auto-tune

Note. Auto-tune is not available for Auto/Manual Station, Indicator or Ratio Station

templates, or when boundless or heat/cool control types are selected.

Information.

• Auto-tune optimizes process control by manipulating the COMMANDER 500 output and then monitoring the process response.

• At the end of an auto-tune, the control parameters are updated automatically.

• Before starting auto-tune, the process variable must be stable.

• The COMMANDER 500 monitors the noise level of the process variable for 30 seconds and if it is greater than 2% of the engineering range the auto-tune is aborted.

• The COMMANDER 500 selects either 'start-up' or 'at set point' tuning automatically, depending upon the level of the process variable relative to the control set point.

2.13.1 Start-up Auto-tune

If the process variable is more than ±10% from the set point, 'start-up' tuning is carried out.

• 'Start-up' tuning – steps the output to drive the process towards the set point. The process response to this step change is monitored and PID parameters are calculated.

• The output step applied = % deviation from the set point x 1.5.

• If no errors exist, the COMMANDER 500 enters auto mode and begins to control the process using the new PID parameters.

• If an error occurs during the auto-tune, the COMMANDER 500 reverts to manual mode with the control output set to the default output value. An error message is displayed in the operator level – see Table 2.1.

2.13.2 'At Set Point' Auto-tune

If the process variable is within 10% of the set point, 'at set point' tuning is carried out.

• 'At set point' tuning – manipulates the control output to produce a controlled oscillation of the process.

• A step change of ±10% of the starting output value is applied initially. This is adjusted to give an amplitude of oscillation 3 times the noise level.

• Once the amplitude and period of oscillation are consistent (minimum 2 cycles, maximum 4 cycles) PID parameters are calculated.

• If no errors exist the controller enters auto mode and begins to control the process using the new PID parameters.

• If an error occurs during the auto-tune, the controller reverts to manual mode with the control output set to the default output value. An error message is displayed in the operator level – see Table 2.1.

Notes For Special Cases.

Cascade Control – the slave loop must be tuned before the master loop. The slave must be

placed into local set point mode (cascade disabled) and the slave set point adjusted to the required value prior to tuning.

Feedforward Control – during an auto-tune with a controller with feedforward the feedforward

signal is not applied. The feedforward gain and bias values are not changed by the auto-tune and must be adjusted separately.

Time Proportioning – the cycle time must be set prior to running an auto-tune. The cycle time is

not changed by the auto-tune.

The Control Efficiency Monitor can be used either to compare the relative performance with different tuning parameters, or when fine tuning the PID settings, to give optimum control.

When the set point is changed, auto mode is selected or following a power failure, input failure or a large load disturbance, the control monitor performs a series of measurements to indicate the effectiveness of the current control parameters.

Fig. 2.14 Control Efficiency Monitor Parameters

2.14.1 Manual Tuning

The Control Efficiency Monitor may be used for manually tuning the PID parameters. The following method describes how to tune the controller for 1/4 wave damping:

a) Set the integral and derivative action times to OFF. b) Set the proportional band (PB) to a low setting. c) Apply a small set point change. d) Use the Control Efficiency Monitor to note the decay ratio. e) If the decay ratio > 0.25, increase the Proportional Band until decay ratio = 0.25

If the decay ratio < 0.25, decrease the Proportional Band until decay ratio = 0.25

f) Leave the proportional band at the setting which gives 0.25 decay ratio and, using the Control

Efficiency Monitor, note the period between peaks.

g) Calculate and set the following parameters:

Integral action time = Period/1.5 Derivative action time = Period/6

Note. The manual tuning facility must not be used with boundless motorized valve control, as

an Integral Action Time is required for these applications.

3.5.2 Valve Setup (Boundless Types) – Fig. 3.4

A ‘boundless’ process controller provides an output that is effectively the time derivative of the required regulator position, i.e. the COMMANDER 500 signals the regulator, not where to go to (position derivative), but in which direction to travel and how far to move, by a series of integral action pulses. Thus, the COMMANDER 500 does not need to know the absolute regulator position and is unaffected when regulator reaches the upper or lower limit, as determined by the regulator’s limit switches (giving rise to the term ‘boundless’).

When a deviation from set point is introduced the regulator is driven, for a length of time equivalent to the proportional step. The regulator is then driven by integral action pulses until the deviation is within the deadband setting.

Local Set Point Tracking – the local set point tracks the process variable

when manual mode is selected. Applies to master and slave set points with cascade templates.

Remote Set Point Tracking – local set point tracks the remote set point

when in remote set point mode. If the controller is put into manual mode the set point reverts from remote to local. Also applies to the local and remote ratio when the ratio controller template is selected.

Set Point Limits

The set point limits define the maximum and minimum values to which the local and/or remote set points can be adjusted.The set point limits do not apply when in Manual mode with local set point tracking enabled. If the set point is outside its limits when Automatic mode is selected, the set point value can only be adjusted towards its limits. Once within the limits they apply as normal.

5.7.1 Thermocouple (THC) Inputs

Note. Use the correct compensating cable

between the THC and the terminals – see Table 5.1.

Automatic Cold Junction Compensation (ACJC) is incorporated by use of CJ sensors wired across the input terminals of I/P1 and I/P3 – see Fig. 5.12.

Alternatively, the CJ sensor can be mounted remotely at the point where the thermocouple cable terminates into copper cable, e.g. where cables enter an instrument panel – see Fig. 5.13.

It is possible to use an external fixed cold (reference) junction, if the instrument is programmed for use with millivolt inputs and the appropriate thermocouple linearizer is selected. This is only possible via the PC configurator.

The Auto/manual Station provides a backup for a Master controller. In normal operation the COMMANDER 500’s current output follows the master

controller’s output value. A fault in the master system can be identified either by detecting a low signal on the master output

signal (template 4). When a fault is detected the COMMANDER 500 selects manual mode with its output either set to the last vali

or to a configured output value – see Section 4.6/ Control Configuration/ Configured Output 1. When the master signal is restor

The auto/manual station can be used in series or in parallel with the master output signal – see Fig. A1. Parallel operation is
