Modbus data communication between AC900F and AC800MHI through CI867 Module
In 1 project we are using Modbus TCP/IP communication between AC800MHI and AC900F.
We are able to get the data from AC800MHI(for SIL application) to AC900F, but when we are writing the data from AC900F to AC800MHI , the data (Integrer) is going , but not holding. It is coming momentary and then becoming zero.
We are using control Builder safe for AC800MHI and Freelance 2013 for AC900F.
When we are installing Freelance 2013 software in same system where we have installed Control Builder safe, The OPC communication is not happening, We have installed the OPC Gateway of freelance, in order to send the data on OPC protocol fromn AC900F to Front end third party server.
Please tell what can be the reason for this.
