Figure 6.3 Application Using Process Vari-
able Retransmit
To set up this application, you would do the following:
1. First, set up the standard control loop parameters ac-
cording to the furnace application, in this case on loop
1.
2. Select another unused PID output for retransmitting
the thermocouple value (for example, loop 2 heat out-
put).
3. Change the display to loop 2, and then enter the three-
key sequence (
ENTER
, then
ALARM ACK
, then
CHNG SP
)
and go to the first screen in Table 6.1.
4. Follow the steps in Table 6.1 to configure the process
variable retransmit option.
5. After following the steps in Table 6.1, press
BACK
sev-
eral times until the normal loop display appears. The
controller will now produce an output on loop 2 which
is linear and proportional to the loop 1 process vari-
able.
