Modbus TCP/IP to Modbus Serial Communication Module

PLX31-MBTCP-MBS

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.

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.

Node Address

1 to 247 (software selectable)

Status Data

Error codes, counters and port status available per configured slave port
