Something strange is happening:

I have a Modbus TCP bridge (Z-KEY by Seneca) and 3 modbus devices, everything is working fine but when I try to write a holding register (with write_multiple set to true as the manufacturer recommend) it doesn't work. For example, I can read this register, but I can't write it.

Code:
{    "name": "Set umidità relativa",
            "bus_datatype":    "int16",
            "address": 0,
            "type": "register",
            "write_multiple" : true,
            "writable": true,
            "units": " %"
            },


I tried with Modscan and everything works fine, also all the coils are managed correctly from Spacelynk...only write holding registers function seems broken.

Any ideas?
