Fieldbus interface

The fieldbus interface is configurable as either Profibus DPV0/V1 or DeviceNet. Both
Fieldbus interfaces support control and status – refer to the specific data map below for
details.
Note that external power, 5 to 24 VDC, is required for this interface to operate. (Ensure that
switches 7 and 8 of the DIPswitch on the communication card, are ON.) A GSD file is
provided on the GE Multilin website http://www.gedigitalenergy/com .
To enable the Profibus physical interface, ensure that switches 3 and 4 of the DIP switch on
the communications card (on the CPU module) are ON, and that switches 1 and 2 are OFF.
The external connections through the Fieldbus interface are as follows:
