4.1. Modbus

TCP/IP

Interface

The Modbus/TCP interface is attached to the TCP/IP stack that is implemented within

the OME-ET-7000/OME-PET-7000 module, and will listen to all communications that

come in on Modbus/TCP registered Port 502.

The Modbus/TCP client uses the standard TCP method for communicating with the

OME-ET-7000/OME-PET-7000 module. UP to 12 connections are possible at one

time. If there are 12 active connections, any attempt at any more connections is

ignored.
