Modbus tcp-ip problem

[Domoticatorino]

Hi there,
I am trying to integrate a PLC modbus with homelynk. I have imported the profile file as follow:

{
"manufacturer":"VRA",
"description":"Demo",
"mapping":[
{"name":"Valvola","bus_datatype":"1","datatype":"bool","type":"coil","address":8970,"writable":false},
{"name":"Valvola","bus_datatype":"1","datatype":"bool","type":"coil","address":8969,"writable":false},
{"name":"Valvola","bus_datatype":"1","datatype":"bool","type":"coil","address":8971,"writable":false},
{"name":"Boost","bus_datatype":"1","datatype":"bool","type":"coil","address":9,"writable":true},
{"name":"Temp ambiente modbus","bus_datatype":"9","datatype":"int16","type":"register","address":8961,"value_multiplier":0.1,"writable":"false"},
{"name":"Temperatura Air Fresh","bus_datatype":"9","datatype":"int16","type":"register","address":8988,"value_multiplier":0.1,"writable":"true"},
{"name":"Temperatura Air Return","bus_datatype":"9","datatype":"int16","type":"register","address":16391,"value_multiplier":10,"writable":"true"},
{"name":"Temperatura Air Return","bus_datatype":"9","datatype":"int16","type":"register","address":16391,"value_multiplier":0.1,"writable":"false"},
{"name":"Temperatura Air Supply","bus_datatype":"9","datatype":"int16","type":"register","address":531,"writable":"false"},
{"name":"Velocità","bus_datatype":"8","datatype":"uint16","type":"register","address":779,"writable":"true"},
{"name":"Temperatura Air Exhaust","bus_datatype":"9","datatype":"int16","type":"register","address":532,"writable":"false"}
]
}

Communication is ok, temperature information is ok but I do not the reason why I cannot communicate with address 8970, 8969 and 8971.


What do you think? 
Thanks.
