===========================

About

$3

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

$3

- 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)

$3

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

$3

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