A.3 Parameter assignment and structure of the module and channel parameters
Channel parameters
The channel parameters of each channel parameter block are subdivided into channel
parameters for the digital output, channel parameters for the digital input and channel
parameters for the analog input including HART.
If the I/O module is operated in digital-only mode, each channel parameter block only contains
the channel parameters for the digital output (2 bytes) and the digital input (4 bytes).
x = 12 + (channel number * 6); with channel number 0...15
If the I/O module is run in mixed mode, the channel parameters of the digital output are followed
by the channel parameters for the analog input including HART (14 bytes).
x = 12 + (channel number * 20); with channel number 0...15
The figures below show the structure of the channel parameters for channels 0...15.
All unused bits and the bits or bytes marked as "reserved" must be set to zero.
You activate a channel parameter by setting the corresponding bit to "1" or the corresponding
value.
