2: Using the ProtoCom/ProtoCom-Lon
This chapter outlines the procedure for setting up communication between the Proto-
Com/ProtoCom-Lon and an EIG meter.
2.1: Step One - Configure Modbus Communication Settings
The ProtoCom/ProtoCom-Lon is designed to connect to either the RS485 Modbus port
or the RJ45 Ethernet port of an EIG power meter and to convert the serial or Ethernet
communication to the desired protocol. Depending on the meter’s point count (see
Section 1.2), the ProtoCom/ProtoCom-Lon can communicate with more than one
meter. Each meter must have an independent RS485 Modbus address or IP
address.See the example configuration below.
