Hi Sander,
I tried to replicate your issue on my side, however I didn't see the null exception you saw.

The updated module microsoft/azureiotedge-modbus-tcp:0.0.1-amd64 fixes my issue with the invalid start address.
I used thin device twin (as seen above, I added TcpPort, RetryCount, RetryInterval and CorrelationID to prevent the info lines).
"desired": {
"PublishInterval": "5000",
"SlaveConfigs": {
"Slave01": {
"SlaveConnection": "/dev/ttyS0",
"BaudRate": "9600",
"DataBits": "8",
"StopBits": "1",
"Parity": "NONE",
"FlowControl": "NONE",
"HwId": "Adam4168U1",
"Operations": {
"Op01": {
"PollingInterval": "5000",
"UnitId": "1",
"StartAddress": "00017",
"Count": "8",
"DisplayName": "Relays",
"CorrelationId": "Message8Coils"
}
},
"TcpPort": "502",
"RetryCount": "10",
"RetryInterval": "100"
}
}
When theis Module Twin is sent, is results in a good response. I get the values of the coils:
8/28/2018 10:47:47 PM> Device: [linux6900], Data:[{"machine":{"temperature":101.08185656174635,"pressure":10.123249481717938},"ambient":{"temperature":20.733080430064852,"humidity":25},"timeCreated":"2018-08-28T20:47:47.9496227Z"}]

'content-type': 'application/edge-modbus-json'
So I change the 00017 into 17:

Op01 has invalid StartAddress 17, remove from dictionary...

The response is ok. 17 is rejected.
So I switch back to 00017:

00023: 0
And I get a good response with valid values again.
I do not have any issues anymore. The response is clear.
