Interfacing a Modbus TCP client to a Sigma IC3 Modbus controller


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


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


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.


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