    MODBUS TCP TO MODBUS RTU

    I am working on a communication link between an Emerson Ovation DCS and an ABB AC410 controller. The Emerson talks modbus TCP and the AC410 speaks modbus RTU. I want to purchase an easy to configure device to link the two. I saw in a previous post a recommendation of a device from Moxa. I...
