● Data record 65 for channel 1
● ...
● Data record 78 for channel 14
● Data record 79 for channel 15
For the configuration as a 2 x 8-channel module, the module has 2 submodules with eight
channels each. The parameters for the channels are located in data records 64 to 71 and
are assigned as follows:
● Data records 64 to 71 for channels 0 to 7 (submodule 1)
● Data records 64 to 71 for channels 8 to 15 (submodule 2)
