MR-DIO-1 6-channel digital I/O module, Modbus RTU
Why choose the MR-DIO-1?
The MR-DIO-1 is an expansion module for the digital inputs and outputs of PLCs or other devices operating on the RS-485 Modbus RTU network.
What does this mean in practice?
- The module provides 6 universal digital channels.
- Each channel can function as a digital input or a digital output, depending on the configuration and connection method.
- Output control and input reading are carried out via Modbus RTU.
- Non-volatile memory for output states ensures that they are retained following a power failure.
- Communication interface: RS-485.
- Communication parameters can be configured via Modbus registers.
Reset of communication settings
A DIP switch is located on the underside of the module .
Details on resetting are available in the manual.
MB Config
The programme allows you to test-read values and configure the module’s communication and configuration parameters.
Communication between the module and a PC via theCN-USB-485 USB converter
The programme is free of charge.
