2.2.2 Transmitting the Input Status (I0...I64) by means of TxId1
The module transmits the status of the 64 digital inputs by means of the eight-byte containing message
of the identifier. The length of the message is always eight bytes.
If a 'high signal' applies to an input, the respective bit of the transmitted bytes is set to '1' (on). The
same is valid for the 'low' level of an input.

Table 2.2.1:
Reading the inputs I0 to I64 by TxId1
The enabling of the transmission of the input status, if at least one input signal alternates it’s state is
done by the user parameters ‘
input_change_mask_
...’.
