4.2 Setting the encoder gateway configuration
Once the GSD file has been installed, the encoder gateway can
be found in the SIMATIC MANAGER-> HW Config under
PROFIBUS DP ->Additional Field Devices->Encoders. Select the
appropriate device to be configured. Drag and drop the device
onto the PROFIBUS DP system as shown in the picture below. In
the example below, the HEIDENHAIN DPV2 Gateway was
chosen. If more than one device is connected and is to be
configured, then the following steps need to be performed once
for each connected device.
When dropping the encoder on the BUS a PROFIBUS address
must be assigned, naturally this address must be the same as
assigned on the hardware address switches located inside the
unit.
