Description

I am having problems ingesting data from Modbus using kafka. Following the official documentation, to read a register from Modbus:

 

holding-register:12289[10]

 

But when I tried to implement this in the job of kafka-connector properties I can't ingest any data into the kafka-topic. This is the configuration: 

jobs.modbus-heartbeat.fields=Analog
jobs.modbus-heartbeat.fields.Analog=holding-register:12289:REAL[8]

 It works configuring separately, following the next code:

 

jobs.modbus-heartbeat.fields=Analog0,Analog1,Analog2,Analog3,Analog4,Analog5,Analog6,Analog7

jobs.modbus-heartbeat.fields.Analog0=holding-register:12289:REAL
jobs.modbus-heartbeat.fields.Analog1=holding-register:12293:REAL
jobs.modbus-heartbeat.fields.Analog2=holding-register:12297:REAL
jobs.modbus-heartbeat.fields.Analog3=holding-register:12301:REAL
jobs.modbus-heartbeat.fields.Analog4=holding-register:12305:REAL
jobs.modbus-heartbeat.fields.Analog5=holding-register:12309:REAL
jobs.modbus-heartbeat.fields.Analog6=holding-register:12313:REAL
jobs.modbus-heartbeat.fields.Analog7=holding-register:12317:REAL

 

My question is if there is some way to read an array from the configuration of kafka-connect, like:

jobs.modbus-heartbeat.fields=Analog
jobs.modbus-heartbeat.fields.Analog=holding-register:12289:REAL[8]

 If you could send an example of this I really appreciated, I find the documentation a bit sparse.
