How to remote access and poll Mitsubishi FX5U PLC ?
The MITSUFX IOServer allows the eWON to poll tags on a MITSUBISHI FX series PLC using its RS-422 base unit programming connector.
The MELSEC IOServer allows the eWON to poll tags on a MITSUBISHI Q series PLC using the MC protocol on the Ethernet interface. Beginning with firmware 7.0, the MELSEC IOServer also allows polling FX3U and A series PLCs over Ethernet.
No remote maintenance functionality is provided by either IO server. For remote maintenance the Ethernet routing feature or VCOM feature (serial) of the eWON must be used.
You can learn more about the VCOM solution on the eVCOM software page.
Look in the table below to find which IOServer you need to use to connect your Mitsubishi device and the minimum firmware version required.

KB-0021 Use of Topics for Tag Polling
For each I/O Server, there are 3 topics (A, B, C) that you can define. In those topics you can choose the frequency of polling. You can also specify on which PLC you would like to read the linked Tags.
If you want to poll on more then 3 PLC then do not specify the destination equipment inside the Topic, but specify it in the Tag configuration.
