Description

GS1B-PNS-MR03 enables data communication between PROFINET networks and Modbus RTU networks, allowing field devices with RTU interfaces — sensors, stepper drives, smart measuring devices, instruments and PLCs — can be connected to a PROFINET network with minimal effort.

The gateway provides 3 independent Modbus RTU (RS485) channels (up to 128 configured commands) and supports the standard PROFINET I/O protocol with up to 128 slots and 1440 bytes of exchanged data. Configuration is straightforward and no complex programming is needed.
