Camel-jamod implements a polling consumer for reading the status of 16-bit input registers (for those devices which make them available to Modbus). These are typically used to store values from analog sensors, such as pressure gauges or thermocouples.
When camel-jamod polls a device for its input registers, it will push a message to the Camel route containing an array of InputRegister. This behavior can be modified to only send messages when one or more register values change by specifying changesOnly=true in the URI's query string.
