6.7 Connection of the analog output (1 x AQ)
Unknown assignment of the analog outputs
The assignment of the analog output is not known at the time of connection. The analog
output can be active immediately after turning on the power supply. This may damage parts
of the system.
Do not create a connection with the analog output before you know the assignment.
The analog output is not permanently assigned to a process value in the delivery state.
Assignment of the analog output to the process value as well as its response in the event of
a fault is carried out during commissioning in data record 7.
