node-red-contrib-mcprotocol 1.2.1

Mode-red nodes to Read from & Write to MITSUBISHI PLC over Ethernet using MC Protocol

npm install node-red-contrib-mcprotocol

About

Overview

This is a Node-RED node module to directly interface with MITSUBISHI PLCs over Ethernet using MC Protocol.

Features

  • Both TCP and UDP connections are possible
  • frames 1E, 3E and 4E are possible
  • works for PLC types
    • A (See Note 1)
    • QnA
    • Q
    • L
    • R
  • ASCII and BINARY mode (See Note 2)

Recommendation

If your PLC suports UDP + 4E, this is by far most reliable.

NOTES

  1. For A series PLC, only 1E frames are supported
  2. ASCII mode is currently not supported for frames 3E and 4E
