Programmers can use the following example as an orientation
for implementation.
Parameter request
(PLC output data)
ReqID = 8 (= Write value)
PNU = 404 (= Record list
setpoint value)
IND = 3 (= Record 3)
Value = 27.89 * 100 = 2789
Preparing for parametrising
Establish status for switching operating mode
Switching is permitted in the statuses Controller disabled",
Controller enabled" or Fault".
Example Controller enabled" status.
