1. Change the bus address of Type 3730-4 to the same bus address as Type 3785. This
can be done over PROFIBUS (DEVICE_ADDRESS parameter), using TROVIS-VIEW
configuration and operator interface or in Code 46 in the positioner.
2. Put positioner into operation (see section 5).
Note: After initialization (in step 2), the positioner is in compatibility (adaptation) mode
(IDENT_NUMBER_SELECTOR parameter in the Physical Block). Do not change this setting.

The relationship between output and input is based on the control system/master class 1.
