Solution 1

Download MX Component from the Mitsubishi Homepage.

there are COM .dlls included to connect via COM/USB/EtherNet to the PLC

they are very stable to use and much easier as writing that communicating stuff on your own. (done that)

very basic example:

VB

Dim _FX_COM As New ACTPCCOMLib.ActFXCPU
_FX_COM.ActBaudRate = 115200
_FX_COM.ActControl = 7
_FX_COM.ActCpuType = 520 'FX3U
_FX_COM.ActTimeOut = 100
_FX_COM.open

Dim value as short = 123

_FX_COM.w_write("D100", value)

Hi F.Xaver

It seems not use TCP/IP to connect PLC.
Do you have other method?

thanks

then use ACTETHERLib.ActFXENETTCP

and _FX_Ethernet.ActHostAddress

RTFM ;)
