4. In the PID Name field, type the name of your PID block.
The name is used to select a PID loop for troubleshooting and plotting
purposes.
5. Under PID Action, click the action option you want.
The action of a PID loop determines how it reacts to a change in the
measured variable. A controller using direct action increases the out-
put when the measured variable increases. A controller using reverse
action decreases the output when the measured variable increases.
6. Under PID Setup, in the Error Deadband field, type the error dead-
band value.
The error deadband prevents the PID output from changing when the
absolute value of the error is less than the error deadband. The error
itself is defined as the difference between the setpoint and the mea-
sured variable.
