Practical configuration examples

7.7.1.

Loop configuration

The example describes the procedure for configuring a PID
with the following features:
• Heat/Cool action;
• K thermocouple input;
• digital control output with Heat/Cool action;
• 2 absolute Maximum and Minimum alarms.
For the configuration of the PID, the following variables
(signals) of the F-MIX module are used:
Type Name
Analog input (AI1)
Digital Output
(DO1)
Digital Output
(DO2)
Digital Output
(DO3)
Digital Output
(DO4)
To configure the PID loop, proceed as follows:
1. Login with level 2 password.
Select SETUP.
2.
