Modbus RTU/ASCII to Modbus TCP protocol converter
PXB-6030D

PXB-6030D is a protocol converter for Modbus RTU to Modbus TCP launched by Zhiyuan Electronics. This device is mounted with guide rail. With a flexible configuration function, it can easily realize the data conversion between Modbus RTU/ASCII serial device and Modbus TCP Ethernet device.

Features

Conversion between Modbus RTU/ASCII and Modbus TCP

4 working modes:

  • RTU_Master ↔ TCP_Slave

  • TCP_Master ↔ RTU_Slave

  • ASCII_Master ↔ TCP_Slave

  • TCP_Master ↔ ASCII_Slave

Modbus TCP supports up to 8 connections;

Support up to 255 Modbus RTU/ASCII slave stations;

Support device ID mapping function;

Support setting protocol conversion timeout.
