4 Channels
The Messenger maps all monitored conditions into channels. Each channel has data
storage and configuration parameters. Data storage holds current value, max/min
values, and other run time data values. Configuration consists of user settable
parameters that define rules on how the data values are to be processed (
Channel
Configuration ).
Every channel in the Messenger is referenced by a fixed channel number, e.g. analog
input channels is always channel 62. There is a set of pre-defined channels (numbers 1-
300) and a set of Modbus channels (numbers 301-380). The Modbus channels are user
configurable for reading/writing digital or analog values from a Modbus RTU slave
device.
