Terminal configuration
KL6071
5
R8: Terminal type:
The terminal type in register R8 is needed to identify the terminal.
R9: Firmware version X.y
The firmware version can be read as an ASCII character string.
3.2.1.1
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.

R14: not used
R15: Alignment bits (RAM)
The analog terminal is set to a byte limit in the terminal bus with the
alignment bits.
Manufacturer parameters
R16 to R30: Manufacturer parameter area (SEEROM)
The manufacturer parameters are specific to each terminal type. They are
programmed by the manufacturer but can also be modified from the control
system. The manufacturer parameters are stored permanently in a serial
EEPROM and are therefore not destroyed by power failures.
These registers can only be modified after setting a code word in R31.
