Mitsubishi ethernet communication

Hi,

I'm trying to send data from 6 PCs to a Q series PLC. Each PC will send only one word to the PLC. How can I do this? Is it possible to do it without using the MX OPC Server software?


Regards,

yes, you could use MX Components for example (comes with demo application) but it's probably not what you expected.

No, the plan is to connect the PCs to a Ethernet Switch where the PLC is already connected.

Is it possible to do it like in AB? I mean, just put somthing like a MSG instruction and then receive the words in the dessignated memory area?

The q-series uses OPEN and READ instructions to pull raw ASCII strings off ethernet into the PLC. These instructions are explained in one of the q-ethernet manuals.

Mexico is covered by the tech support group in Chicago, IL. I know that have a sample PLC program and VB program (for the PC) to demonstrate doing this sort of thing - if you ask nicely...

Thanks!!!
