Quick Start Guide For The DNP Orion To ABB REL 356 Relays Using
Modbus
This Quick Start Guide shall enable the user to attach a REL 356 protective relay to the ORION unit
communicating over a 485 physical cable connection.
Required equipment:
A. ORION UNIT (TABLE TOP or RACK MOUNT)
B. ONE ABB REL 356 PROTECTIVE RELAY
C. IBM Compatible PC with Windows 95, or 98 installed.
D. ONE PONI –M Modbus PONI Card.
E. ONE COMSET UTILITY DISK TO SET THE MODBUS PONI CARD ADDRESS
F. ONE RS 232 to RS 485 PHYSICAL INTERFACE CONVERTER.
G. ONE CABLE ASSEMBLY KIT WHICH CONTAINS:
a. One RS 485 Cable.
b. One Troubleshooting Diskette.
1. It is imperative to realize that the ORION is available in two formats, a 19" rack mount version and a
Table Top version. Please refer to the appropriate diagrams when using this guide. Apply power to
the universal power supply according to the markings on the unit as shown in Figure 1 or Figure 1A
as depicted in illustration 1. The unit accepts voltages from 55 to 200 V a.c. or 20 to 280 V d.c.
