ModBUS communication interface (Bridge-ModBUS)

It is used for data transfer between the UnimaBUS bus (RS-485) on the ModBUS-RTU bus (RS-485) respectively ModBUS-TCP (ethernet). Using this bridge, any data from the ModBUS bus can be transferred in both directions to any device or IO module connected to the Unima-BUS without this device having its own ModBUS interface. The RTU bridge supports both slave and master mode, so it is possible not only to passively transfer data from any UNIMA-KS device (control system, I / O module, ignition, etc.) to the superior system, but also to actively read values from ModBUS sensors, for example. The TCP bridge supports only slave mode
