5.4 Configuring Current Adjusting Type (CAT) Control and/or
Retransmission of Process Variables
Purpose
If the hardware supports analog outputs, during I/O setup you had an opportunity to specify
which process variable or computed value will be associated with each output. An analog output
can be used for scaled retransmission of the value, or for Current Adjusting Type control by
means of an output signal that is directly proportional to the input signal or computed value.
Before using analog outputs, you must configure the related parameter values.
For a discussion of tuning proportional control see Appendix A.
Procedure
The procedure for configuring CAT control and/or retransmission of process variables is shown
in Table 5-2.

If the Analyzer/Controller hardware only supports one
analog output, the screen at the left will be displayed when
CAT/RETRANSMISSION is selected from the menu.

If the hardware supports three analog outputs, the screen
in Step 6 will be displayed when CAT/RETRANSMISSION
is selected from the menu.
If CAT control will be used, select it from the menu.

If the system uses a DE option card, no analog outputs are supported by the hardware. The screen will show “DE
ENABLED”, instead of displaying analog outputs.
