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
