MODBUS RTU, MODBUS TCP, MODBUS ASCII data query and parser

Latest version: 4.0.78 build 917. .

MODBUS is a serial communications protocol for use with its programmable logic controllers (PLCs). Simple and robust, it has since become a de facto standard communication protocol, and it is now a commonly available means of connecting industrial electronic devices.

Advanced PBX Data Logger's MODBUS RTU/ASCII and MODBUS TCP plugin can work in two modes::

  1. Data query and parser - the plugin sends MODBUS requests and process the responses. In this mode the program operates in the Master mode;
  2. Data parser only - in this mode, the plugin waits for responses only. For example, it can work in parallel with other MODBUS master or in the "Spy" mode.

This module has the following features:

  • Can send a valid data request to any MODBUS-compatible device;
  • Can send a request with any MODBUS function;
  • CRC for each data packet will be calculated and verified automatically;
  • Can request bytes, word, double words and single registers;
  • Can poll MODBUS data by a custom interval;
  • Can flexibly parse all received data packets and extract register's values.

The tutorials section contains several examples of how to configure and use this plugin.
