Register description
All registers can be read or written via register communication. They are used for the parameterization of the terminal.
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 delivery state for the following registers:
R33: 0dec
R34: 256dec
R35: 3dec
R36: 10dec
R37: 16383dec
R38: 0dec
R39: 0dec
R40: 1dec
R41: 0dec
R8: Terminal type
The terminal name is contained in register R8: KL2791
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 can not be changed.
R16: Hardware version number
Register R16 contains the hardware version of the terminal.
R29: Terminal type, special version
Register R29 contains the special version of the terminal.
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.
Bit | R32.15 | R32.14 | R32.13 | R32.12 | R32.11 | R32.10 | R32.9 | R32.8 |
Name | - | - | - | - | - | - | - | - |
Bit | R32.7 | R32.6 | R32.5 | R32.4 | R32.3 | R32.2 | R32.1 | R32.0 |
Name | - | - | - | - | - | disWatchdog | - | enUserScale |
Key
Bit | Name | Description | Default | |
|---|---|---|---|---|
R32.15 - R32.3 | - | reserved | ||
R32.2 | disWatchdog | 1bin | Internal watchdog (time adjustable) deactivated | 0bin |
R32.1 | - | reserved | ||
R32.0 | enUserScale | 1bin | 0bin | |
R33: User scaling - offset
The offset of the user scaling when the user scaling (R32.0=1bin) 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=1bin) is enabled is entered in this register.
Example values:
128dec = 0x80 = factor 0.5
256dec = 0x100 = factor 1.0 (default)
512dec = 0x200 = factor 2.0
R36: Watchdog Timeout
This register specifies the timeout in the event of a fieldbus error. The unit is 10 ms (default: 10dec = 100 ms).
R37: Control 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: 16383dec).
The unit is 1. (R32.2=1bin).
R38: Control 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: 0dec).
The unit is 1. (R32.2=1bin).
R39: Setting mode
This register specified the setting mode (see Notes on operation):
0dec: Full-wave control (default)
1dec: Mixed control
2dec: Leading edge phase control (firmware version 2 A or higher)
R40: Behavior after short circuit
This register specifies the behavior after a short circuit:
0dec: Remains switched off:
1dec: switch on again (default):
R41: Mains frequency
This register specifies the mains frequency:
0dec: 50 Hz (default)
1dec: 60 Hz
