1) On a site you have several Metasys N2 controllers that can control data output on Metasys N2.
2) The site has a power meters on Modbus TCP that needs to be monitored by controllers on Metasys N2.
3) Since the Metasys N2 controllers provide data output on Metasys N2 and the Power Meter understands only Modbus TCP a direct data exchange is not possible.

Solution:
The devices can not directly communicate with each other as they are not on the same protocol. Metasys N2 is a Serial protocol, while Modbus TCP is an Ethernet based Protocol. You need something that will convert data from Modbus TCP device to Metasys N2 and vice versa.
ProtoConvert’s Metasys N2 to Modbus TCP converter will be an excellent solution for this requirement. The gateway reads data from the Power/Energy meters on Modbus TCP. It caches this data internally and then provides it on Metasys N2 when requested from the Controllers system.
