The MGate 4101-MB-PBS gateway provides a communication portal between PROFIBUS PLCs (e.g. Siemens S7-400 and S7-300 PLCs) and Modbus devices. With the QuickLink function, I/O mapping can be carried out within a few minutes. All models are protected by a robust metal housing, can be mounted on a DIN rail and offer optional integrated optical isolation.
