Register description

All registers can be read or written via register communication. They are used for the parameterization of the terminal.

Basic configuration is also possible via the PLC using the FB_KL27x1Config function block.

R7: Command register

	User code word For the following commands to be executed, it is first necessary for the user code word, 0x1235, to be entered into register R31.

Command 0x7000: Restore Factory Default Settings
Entering 0x7000 in register R7 restores the factory settings for the following registers:
R33: 0_dec
R34: 256_dec
R35: 3_dec
R36: 10_dec
R37: 16383_dec
R38: 0_dec
R39: 0_dec
R40: 1_decR41: 0_dec (KL2751-0000, KL2751-0011, KL2761-0000, KL2761-0011)

R8: Terminal type

The terminal identifier is contained in register R8: KL2751 or KL2761.

R9: Firmware version

Register R9 contains the ASCII coding of the terminal's firmware version, e.g. 0x3141 = '1A'. The '0x31' corresponds here to the ASCII character '1', while the '0x41' represents the ASCII character 'A'.
This value cannot be changed.

R16: Hardware version number

R29: Terminal type, special version

R31: Code word register

If you write values into the user registers without first entering the user code word (0x1235) into the code word register, the terminal will not accept the supplied data. The code word is reset if the terminal is restarted.

R32: Feature register

The feature register specifies the terminal's configuration.

Legend

Bit	Name	Description		Default
R32.15 - R32.4	-	reserved
R32.3	DimRamp	0_bin	Dimming ramp relative: The time in register R35 relates to the entire process data range (0_dec- 32767_dec). This means that the dimmer terminal requires this time to control from "off" (0_dec) to full scale control (32767_dec).	0_bin
R32.3	DimRamp	1_bin	Dimming ramp absolute: The time in register R35 relates to the current process data change. This means that the dimmer terminal requires this time in order to execute the current brightness change.	0_bin
R32.2	disWatchdog	1_bin	Internal watchdog (time adjustable) deactivated	0_bin
R32.1	-	reserved
R32.0	enUserScale	1_bin	User scaling active (see R33+ R34)	0_bin

R33: User scaling - offset

The offset of the user scaling when the user scaling (R32.0=1_bin) is enabled is entered in this register (default: 0).

R34: User scaling - gain

The gain of the user scaling when the user scaling (R32.0=1_bin) is enabled is entered in this register.
Example values:
128_dec = 0x80 = factor 0.5
256_dec = 0x100 = factor 1.0 (default)
512_dec = 0x200 = factor 2.0

R35: Ramp time

This register specifies the time required

to ramp up from 0 to 32767 (full scale control of the angle) (when R32.3 = 0_bin) or
to execute the current brightness change (when R32.3 = 1_bin).

0_dec: 50 ms
1_dec: 100 ms
2_dec: 200 ms
3_dec: 500 ms (default)
4_dec: 1 s
5_dec: 2 s
6_dec: 5 s
7_dec: 10 s

R36: Watchdog Timeout

This register specifies the timeout in the event of a fieldbus error. The unit is 10 ms (default: 10_dec = 100 ms).

R37: Light value for timeout (on)

This register specifies the light value that is output in the case of a fieldbus error and current process data > 0 (default: 16383_dec).
The unit is 1. (R32.2=1_bin).

R38: Light value for timeout (off)

This register specifies the light value that is output in the case of a fieldbus error and current process data = 0 (default: 0_dec).
The unit is 1. (R32.2=1_bin).

R39: Dimmer mode

This register specifies the dimmer mode:
0_dec: automatic detection (default)
1_dec: Trailing edge phase control
2_dec: Leading edge phase control
3_dec: Rectifier mode, positive (positive half-wave with leading edge phase control)
Do not use this operation mode with firmware version 2E of the KL2751 or with firmware version 1E of the KL2761!
Instead, use the operation mode Rectifier mode, negative with these firmware versions!
4_dec: Rectifier mode, negative (negative half-wave with leading edge phase control)

R40: Behavior after short circuit

This register specifies the behavior after a short circuit:
0_dec: Remains switched off:
1_dec: switch on again (default):

R41: Mains frequency

This register specifies the mains frequency:
0_dec: 50 Hz
1_dec: 60 Hz

Default value: 50 Hz
