We need a RS-485 Power Meter Modbus to SNMP v 2.0 module able to interface with 'standard' commercial smart power meters. These should be programmable to retrieve/translate register (coils) values into SNMP traps. Between 15-30 paramters are needed per individual meter (addressed by unique RS-485 bus address). Interfaces: RS-485 and Ethernet 100 Mbps. Protocols: RS-485 Modbus RTU and SNMP v 1.0 and 2.0.
Modbus functions needed: 1(read coils), 3(read registers), 5(write coil), and 6(write register)
