Output-related Function Settings
Use these parameters to configure control output for individual loops, as required. They
can be used for setting control output cycle time and rate-of-change limits.

Alarm-related Function Settings
Use these parameters to set up the operation of the alarm functions for individual loops
as required. They can be used to set up the alarm type, hysteresis, and ON delay timer.

PID Parameters
Use these parameters to configure PID control-related functions for individual loops.
They can be used for specifying set points, alarm preset values, proportional band,
integral time, and derivative time. Up to four parameter groups can be defined for each
loop.
You need to execute a specific procedure every time to update stored set point values.
Otherwise, stored set points will not be updated so the parameters revert to their last
stored values whenever the module is turned off and then on again. For details, see
Section B2.4, "How to Back up SP Values to EEPROM."
