Modbus TCP/IP

Modbus TCP/IP is a serial communications protocol published by Schneider Electric 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. The main reasons for the use of Modbus in the industrial environment are:

  • It has been developed with industrial applications in mind
  • It is openly published and royalty-free
  • It is easy to deploy and maintain
  • It moves raw bits or words without placing a lot of overhead

The Hardy Modbus-Link option for the HI 3000 series of instruments allows data from the monitoring system to be directly logged into a Microsoft® Excel or Visual Basic program.
