The MOD-ETH converts between Modbus TCP and Modbus RTU or ASCII on a RS485 link. The MOD-ETH can support up to 128 RS485 slaves and is optimized for use with the Modbus-Slim range of IO units. Up t o 4 Modbus TCP clients can access salves at the same time either directly or via an internal register look-up table. In addition, the MOD-ETH has a watchdog, 4 digital inputs and 3 relay outputs.

The MOD-ETH module is an innovative device converting Modbus TCP into ModbusRTU/ASCII. The device has the Ethernet and RS485 interface, 4 digital inputs with counters and 3 relay outputs. All the inputs are insulated from logic with the aid of optoisolators.

The MOD-ETC has 2 operating modes

Dumb Gateway - Modbus TCP requests (from up to 4 clients) are converted to Modbus RTU or Modbus ASCII and transmitted on teh RS485 bus. Response messages are conmverted vabk to Modbus TCP and sent to teh requesting client.
Device Table - The MOD-ETH can be configured with a devie table list. the MOD-ETH then polls the Modbus RTU or ASCII slaves and stores retuned values in its own internal Modbus TCP registers. TCP client can then request data fom these internal registers. This vastly improves response times.

The MOD-ETH can connect up to 128 I/O modules Modbus via the RS485 interface. The MOD-ETH also sports a "Quick Connect" IDC header for connection to the MODBUS-SLIm range of IO units. This simplifies wiring and makes for a compact expandable Modbus TCOP IO solution.

Ethernet Modbus TCP data acquisition

The module is equipped with a set of LEDs used to indicate the status of inputs and outputs useful for diagnostic purposes and helping to find errors. Module configuration is done via built-in website or USB by using a dedicated computer program. You can also change the parameters using the MODBUS protocol
