Currently looking for the best way to go about connecting to a Keyence 7500. Has anyone had success with this, that has a KV-EP21V and an I/O card?

The Mitsubishi driver apparently works with many of the Keyence PLCs, see:

> [@Can ignition communicate with Keyence PLC?](https://forum.inductiveautomation.com/t/can-ignition-communicate-with-keyence-plc/57508/13):

> Using 8.1.44+ and the Mitsubishi driver with Q-series selected will allow communication with Keyence KV-series PLCs. The following tables translate Keyence device (memory area) names to Mitsubishi.

The Melsec protocol works with the KV PLCs. Not sure it works with the Vision systems, or through the EIP adapter card.

That EIP adapter card definitely **does** work with my 3rd party EIP driver's Scanner mode.

Thanks. We got it working we think. Ran into this thing on an emergency integration job and hadn’t worked with one before.

Now it’s just down to setting up the interaction with our MES.

Does seem to be a little quirky though as I try to write things. Also having to byteswap the strings.
