Interfacing to Yokagawa DCS


Thread Starter

Michael Sing

I need to know the available means to interface Modicon PLCs to Yokagawa DCS at the hardware level and software level (HMI). My preference is to interface to the Yokagawa HMI usng Modbus TCPIP or OPC if available.
More information is needed. What type of Modicon PLCs? Which PLC families is important as only certain ones support ethernet via Modbus/TCP. What is the Yokogawa DCS? Is it a PC? Is there room to add an ISA or PCI card to it? What is it's operating system? Modicon has the drivers and cards to hook Modbus Plus to a PC or ethernet and use an OPC server to get the data from the PLC.
