5.4 Register description
All registers can be read or written via register communication. They are used for parameterizing the
terminal.
R0: Status word
The status word contains information about internal states, and provides an indication of errors that have
occurred.

Bit Name Description
R0.15 - reserved
R0.14 NoControlPower 1
bin
The 24 V control voltage is not present at the power contacts
R0.13 OpenLoad 1
bin
Open load / broken wire
R0.12 OverCurrent 1
bin
Overcurrent in the driver stage
R0.11 UnderVoltage 1
bin
Supply voltage less than 7 V (only on the KL2545)
R0.10 - reserved
R0.9 LowVoltage 1
bin
The supply voltage is 10 V less than the switch-on voltage (only
on the KL2545)
R0.8 OverTemperature 1
bin
The internal temperature of the terminal is greater than 80 ℃ (see
R5 [
}
41] ) (only on the KL2545)
R0.0-R0.7 - reserved
R1: Set position
You can specify the desired position, with which the terminal is to be loaded, here.
R2: Coil voltage
You can read the coil voltage here. The unit is 1 mV (for example: 4800 = 48 V).
R3: Supply voltage
You can read the power supply voltage here. The unit is 1 mV (for example: 4800 = 48 V).
R5: Temperature register
The internal temperature of the terminal can be read, in °C, through register R5. The terminal will set bit SB.5
[ } 38] in the status byte as a warning if the temperature exceeds the threshold of 80°C. When the
temperature falls back below 60°C, bit SB.5 [ } 38] will automatically be reset.
R6: Status byte
The status byte of the relevant channel is mapped here in addition.
