PROFINET Device to Modbus Serial Gateway

PLX31-PND-MBS

The PROFINET device to Modbus Serial gateway offers bi-directional data transfers between a PROFINET Controller and Modbus serial (RTU and ASCII) devices. The serial port can be configured as either a Modbus master or slave. The PROFINET interface operates as a PROFINET device (slave).

The PLX31-PND-MBS gateway is a stand-alone DIN-rail mounted unit that provides Ethernet connectivity for network communications, remote configuration, and diagnostics. The onboard SD Card slot (SD card optional) is used for storing configuration files that can be used for recovery, transferring the configuration to another gateway, or general configuration backup.
