Q series Mistubishi PLC and Visual basic

Hello Everyone,

I want to send and receive data from Mitsubishi PLC and Visual Basic.

Data is only of string and numbers.

so what could software and hardware require and step to do it ?

You 'can' use MX Components from Mitsubishi, although as some people have pointed out in the past it's not completely "hassle-free"... I've used it in the past with success, but I would suggest you look into using an OPC server and interact with it using VB. Alternatively you can write the MC protocol (documented) and use a serial or Ethernet card in the PLC. MC protocol is a binary protocol for the newer CPU's and pretty straight-forward to develop...

Thank you for the reply.

My PLC is Q series and it's having inbuilt Ethernet Port.

can i use it ? 

and If i want to use MC protocol how should i go forward ?

EDIT: You want to use 4E frame.

If your PLC is Q-Serial with Ethernet port, just use the TCP/UDP socket communication.
