Interfacing a Modbus TCP client to a Sigma IC3 Modbus controller

Issue

The IC3 Modbus IP interface is a client. How can this be linked to another Modbus IP client such as the Carrier i-VU gateway?

Product Line

Satchwell Sigma

Environment

  • IC3 Modbus IP Client server
  • Sigma
  • Carrier I-VU

Cause

The IC3 Modbus only supports the IP client and cannot be directly connected to another IP client.   Other systems such as Carrier are similarly only IP client.

Resolution

Using the BCX1 as a Modbus IP server to hold a mapping table will allow both clients to read/write data to it.
