PLX31-MBTCP-MBS4 Our Modbus TCP/IP communication gateways offer bidirectional data transfers between devices on dissimilar networks. Our Modbus TCP/IP Driver uses Multiple Clients and Servers for faster data throughput. Protocol conversion gateways are the ideal solution for distributed networks when adding a remote rack becomes too costly. The PLX30s are stand-alone DIN-rail mounted gateways that provide one Ethernet port for communication, remote configuration and diagnostics, and up to four (4) serial communication ports. The PLX30 gateways also come with an SD Card slot (SD card optional) for storing configuration files. In the event of a failure the SD card can be transferred to another gateway reducing downtime. These gateways contain a 4000 word database, includes a wide input power range (10 Vdc – 36 Vdc), and an extended temperature range (-25°C to 70°C). The PLX30 gateways include all the necessary cables required for communication.

Serial Port Isolation 2500 Vrms port signal isolation per UL 1577 serial port communication signal uses RF(Radio Frequency) modulation signal as isolation media, IC chip model is SiliconLabs Si844x(Si8440,Si8441,Si8442). Protocols MBS Protocol Specifications MBS Protocol Specifications Protocol Specifications Modbus Master A port configured as a virtual Modbus Master actively issues Modbus commands to other nodes on the Modbus network. The Master ports have an optimized polling characteristic that polls slaves with communication problems less frequently. Command List Up to 100 commands per Master port, each fully configurable for function, slave address, register to/from addressing and word/bit count. Polling of Command List Configurable polling of command list, including continuous and on change of data, and dynamically user or automatic enabled. Status Data Error codes available on an individual command basis. In addition, a slave status list is maintained per active Modbus Master port. Modbus Slave A port configured as a Modbus slave permits a remote Master to interact with all data contained in the module. This data can be derived from other Modbus slave devices on the network, through a Master port, or from the module.
