Assigning the channels to fields
To summarize output channels and controlling them with a setpoint value, you can
assign them to field type 1 or 2.
Field type 1 combines successive channels.
Field type 2 combines any channels.
You can only select one field type. You can reset the selection of the field type via
data record 190 or by disconnecting the 24 V power supply from the HCS.
