Modbus TCP/IP to Modbus Master/Slave Gateway – 4 Port

PLX31-MBTCP-MBS4

Modbus TCP/IP to Modbus Master/Slave Gateway – 4 Port

PLX31-MBTCP-MBS4

ProSoft Technology’s Modbus® TCP/IP to Modbus® Serial four-port Serial gateway allows high-speed bi-directional data transfers between Modbus® TCP/IP-enabled PACs and Modbus® Serial devices. Modbus® Serial devices are widely used in nearly every industry and include SCADA systems and Power Monitors. Four Serial ports allow for connectivity of up to 400 Modbus® Serial devices, reducing the amount of gateways required for your application.

In addition, the gateway includes several features that allow for simplified integration, reduced commissioning time and optimized performance.

A conformal coating option is available for this product.

Features and Benefits

  • Gateway includes a SD card slot (SD card optional) for storing configuration files. This can be used for disaster recovery.
  • Four Serial ports allow for connectivity of up to 400 Modbus® Serial devices, reducing the amount of gateways required for your application.
  • Supports up to 20 simultaneous client & server connections, allowing for faster communication between devices such as HMIs, SCADA systems, power monitors and flow computers, among others.
  • ProSoft Discovery Service: This utility allows your PC to see the gateway and change its default IP address without being on the same subnet as the module.
  • Secure module configuration via module switch (v1.04 and greater).
  • Up to 10,000 16-bit registers can be used to exchange large amounts of data.
