Modbus TCP/IP communication to Kongsberg BMS

Hi all,

I’m trying to communicate with Kongsberg BMS System through TCP/IP with a ALE111 Yokogawa card. There’s a problem when trying to receive analog values from the slave side but digital signals are being received without error. According to the Kongsberg side they want us to provide redundancy Anyone can help me on how to provide redundancy on Yokogawa system if there’s only one TCP/IP cable coming from slave side.
Thank you
