ODOT CT-5321

Modbus Serial Port Module

Product Feature:

CT-5321 Modbus Serial Port Module

Module Description

The Modbus serial port module supports 1 channel RS485/RS232 /RS422(optional), supports Modbus RTU/ASCII protocol, and supports master, slave and free transparent transmission mode.

The serial Module CT-5321 could be applied with the adapter modules, so it could convert Modbus into other protocols such as Modbus TCP, Profinet, EtherCAT, EtherNet/IP, etc. When the module is used, serial port parameters and Modbus instructions should be configured in IO Config software.

Devices with RS485/RS232/RS422 interface, which support modbus-RTU/ASCII, could be applied with CT-5321 to realize interconnection with upper PLC or upper computers. CT-5321 could be applied with devices such as: PLC, DCS, remote IO, VFD, motor start protection device, intelligent high and low voltage electrical apparatus, power measurement device, intelligent field measurement equipment and instruments, etc.
