Channel parameters
Each channel parameter block contains the cable parameters for the digital input (4 bytes).
The following 󹪝gure shows the con󹪝guration of the channel parameters for channels0 to 15.
x = 12 + (channel number * 4); with channel number 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.
