Process data monitoring time (setpoint timeout)
The "Setpoint timeout" only applies for access to process data (40100 ... 40109, 40110 ...
40119). The "Setpoint timeout" is not generated for parameter data (40300 … 40522).
In parameter p2040 you define the time for cyclic data exchange for process data.
Setting range 0 - 2000 s.
The time depends on the amount of data to be transferred and the control.
"Setpoint timeout" (F01910) is issued by the Modbus if p2040 is set to a value > 0 ms and no
process data is requested within this time period.
In parameter p8840 you define the time for cyclic process data exchange.
Setting range 0 - 2000 s.
The time depends on the amount of data to be transferred and the control.
"Setpoint timeout" (F08501) is issued by the Modbus if p8840 is set to a value > 0 ms and no
process data is requested within this time period.
