Register description
KL6051 9
Type registers R8 - R15 Registers in the terminal’s internal ROM der Klemme
The type and system parameters are programmed permanently by the
manufacturer and can only be read by the user but cannot be modified.
R8: Terminal type:
The terminal type in register R8 is needed to identify the terminal.
R9: Software version X.y
The software version can be read as an ASCII character string.
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 loca-
ted 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
Data type register
0x00 Terminal without valid data type
0x01 Byte array
0x02 1 byte n bytes structure
0x03 Word array
0x04 1 byte n words structure
0x05 Double word array
0x06 1 byte n double words structure
0x07 1 byte 1 double word structure
0x08 1 byte 1 double word structure
0x11 Byte-array with a variable logical channel length
0x12 1 byte n bytes structure with a variable logical channel
length (eg 60xx)
0x13 Word-array with a variable logical channel length
0x14 1 byte n words structure with a variable logical channel
length
0x15 Double word array with a variable logical channel length
0x16 1 byte n double words structure with a variable logical
channel length
R14: not used
R15: Alignment bits (RAM)
The analog terminal is set to a byte limit in the terminal bus with the align-
ment bits.
Manufacturer parameters R16 - R30 is the area of the "Manufacturer parameters" (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.
