Modbus Mapper refresh not working - joost001 - 09.11.2017
I'm experiencing a problem with the Modbus mapper and my SMA inverter.
I have been able to load a correct profile for 1 register and map it to a knx object.
Poll interval is set at 10seconds. I see that the KNX object is correctly updated a first time. However, any changes afterwards are not refreshed in the KNX object.
Is there anything else that I would need to investigate? If I remove the mapping and create a new one, the value gets written again only once.
Anybody any clue?
regards,
Joost

Post your profile and also check if there are entries in Error log.

Hi Admin,
I found the issue. the inverter still had a DHCP address which actually changed during my tests. as a result the modbus tcp connection failed. With a fixed IP the problem is resolved.
I will post my full sma profile once I added the other registers (currently only defined 1 for test).
regards,
Joost

Hi,
I wrote here because I have the same problem. I am usign RTU Modbus system. Profile is the one below:
{
"manufacturer":"France Air",
"description":"Ventilazione Meccanizzata",
"mapping":[
{"name":"System Power","bus_datatype":"1","datatype":"bool","type":"coil","address":0,"writable":true},
{"name":"Boost","bus_datatype":"1","datatype":"bool","type":"coil","address":9,"writable":true},
{"name":"Temperatura Air Fresh","bus_datatype":"9","datatype":"int16","type":"register","address":529,"writable":"false"},
{"name":"Temperatura Air Return","bus_datatype":"9","datatype":"int16","type":"register","address":530,"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"}
]
}
Everything is fine the first time when I set the profile then it seems data are not refreshed. In Error log there is nothing about modbus. When I test the RTU reading variable is good.
Any suggestion?
Thanks.
