CHAPTER 11: METER WITH OPTIONAL INTERNAL NETWORK (COMM OPTION 1)
Figure 11-1: Meter Communication with Network Option/Daisy Chained Meters
The Internal Network Option of the EPM 9450/9650 meter is an extremely versatile
communications tool. The Internal Network Option:
• Adheres to IEEE 802.3 Ethernet standard using TCP/IP
• Utilizes simple and inexpensive 10/100BaseT wiring and connections
• Plugs into your network using built-in RJ45 jack
• Is programmable to any IP address, subnet mask and gateway requirements
• Communicates using the industry-standard Modbus/TCP and DNP LAN/WAN
protocols.
With the Internal Network Option, the EPM 9450/9650 meter's Port 2 becomes a "gateway"
that allows access to additional EPM meters via the LAN. Simply connect a daisy chain of
EPM meters together via RS485, each with its own device address and using the same
baud rates. With this option, you can access any of those instruments via the single LAN
connection.
The Internal Network Option allows multiple simultaneous connections (via LAN) to the
EPM 9450/9650 meter. You can access the meter with SCADA, MV90 and RTU
simultaneously.
The Internal Network Option allows multiple users running GE Communicator software to
access the meter concurrently.
