Hi,

LOGO! can exchange data with devices with Modbus TCP and S7 Classic vis TCP. If the charger can communicate with Modbus TCP then it should work.

If the charger use another communcation protocoll, then is lots of cases there is a converter/gateway availalbe. 

Please note: LOGO! only supports integer calculation including sign. So the range is from -32767 till +32767.

Hope this helps

Thanks! Yes, it helped. 

Generally, the charge boxes communicate with a specific protocol, OCPP, but as you say, this should be possible to convert.

I'll dig in deeper on the topic ...
