PARAMETERS AND HOW TO ACCESS THEM
Parameters are settings, within the controller, that determine how the controller will operate.
For example, alarm setpoints are parameters that set the points at which alarms will occur.
For ease of access, the parameters are arranged in lists as shown in the navigation diagram on
Pages 2-10 and 2-11. The lists are:
Home list
Run list
Programming list
Alarm list
Autotune list
PID list
Motor list
Setpoint list
Input list
Output list
Communications list
Information list
Access list.
Each list has a ‘List Header’ display.
