Register description
10 KL5111-0000
R10: Data length
R10 contains the number of multiplexed shift registers and their length in bits. The bus coupler sees this
structure.
R11: Signal channels
In comparison with R10, the number of logically existing channels is located here. For example, one
physically existing shift register may consist of several signal channels.
R12: Minimum data length
The respective byte contains the minimum data length of a channel to be transferred. If the MSB is set,
then the control/status byte is not necessarily needed for the function of the terminal and, with appropriate
configuration of the coupler, is not transferred to the control system.
R13: Data type register

R14: not used
R15: Alignment-Bits (RAM)
The analog terminal is set to a byte limit in the terminal bus with the alignment bits.
