6.5 CS1 SOFT-WIRE LIST MODIFICATIONS

Table 6-4 lists values that can be entered into designated soft-wire list datapoints to alter CS1 func-
tionality.

Table 6-4. CS1 Soft-Wire List Modifications

To force control to manual on a momentary contact closure of DI0:

Set B133 = 97

To set controller output to a fixed value while DI0 is an open contact:

Set B160 = 129 and Set C129 to desired value.

To force the output to track AI3 while DI0 is a closed contact and to set the controller to manual
when the tracking operation is ended by opening the DI0 contact:

Set B133 = 0, Set B129 = 128, and Set B159 = 97.

DO0 indicates either Process Alarm 1 or Process Alarm 2 active, and DO1 indicates the Totalizer
0 rollover pulse:

Set B172 = 1 and Set B106 = 224.

DO0 indicates remote and auto while DO1 indicates Process Alarm 1:

Set B170 = 107, Set B171 = 108, Set B172 = 2, and Set B106 = 110.

:

Disable Feed Forward by setting B155 = 122, and C122 = 0.0,
Disable Output Tracking by setting L119 = 0,

For control PV compensated gas flow (linear) with AI2 - pressure and AI3 - temperature:

Disable Feed Forward by setting B155 = 122 and C122 = 0.0,
Disable Output Tracking by setting L119 = 0,
Set B122 = 18, and
Set C354, C356 - C359 as required (see IB 53MC5000 Flexible Control Strategies
for compensated gas flow information).

For control PV compensated gas flow (square root) with AI2 - pressure and AI3 - temperature:

Disable Feed Forward by setting B155 = 122 and C122 = 0.0,
Disable Output Tracking by setting L119 = 0,
Set B122 = 19, and
Set C354 - C359 as required (see IB 53MC5000 Flexible Control Strategies
for compensated gas flow information).

To make an Integral (I) only controller:

Set B155 = 122, Set B163 = 30, Set B165 = 2, Set C122 = 0.0,
Set C79 = 1.0, Set C80 = 1.0, and Set C106 = 100.0.
