The Flexy embeds two IO servers dedicated to Mitsubishi PLCs:
- MITSUFX: this IO server allows the Flexy to poll tags on a MITSUBISHI FX series PLC using its serial RS-422 programming connector.
- MELSEC: this IO server allows the Flexy to poll tags on a MITSUBISHI Q series PLC using the MC protocol on the Ethernet interface. It also supports the polling of the FX3U, FX5U and A series over Ethernet protocol.
A summary of the existing situation can be found in the table below:

The remote maintenance functionality is not provided by either IO server. To perform a remote maintenance, the Ethernet routing feature or VCOM feature (serial) of the Flexy must be used.
