Mini Modbus 4DI

User Manual

8.  Configuration software

Modbus Configurator is software that is designed to set the module registers

responsible for communication over Modbus network as well as to read and write the
current value of other registers of the module. This program can be a convenient way to
test the system as well as to observe real-time changes in the registers.

Communication with the module is done via the USB cable. The module does

not require any drivers.

Configurator is a universal program, whereby it is possible to configure all available
modules.
