A Series Ethernet Protocol

2 posts in this topic

Hi everybody: I need to know where I can get a document that explains the ethernet protocol for the A series PLC (AnSH/QnAS(H) Series) I want to develop a Visual Basic interface to communicate this PLC with others devices over Ethernet so I need a detailed explanation about how the ethernet strings are composed. I´m planing to use a A1SJ71E71N-T ethernet module. Thanks in advance for your help.

Your life would be much easier if you use the Mitsubishi MX-Component software. It is fairly cheap, and handles all the communications and is an ActiveX control you can use in your VB programs. Since it handles all comms, you don't need to know the protocol. But if you still want to know the protocol, check out the MC Protocol manual, which you can find on www.meau.com.
