4.3.14.10.22 Environment variables
4.3.14.10.22.1 Operating time in seconds
Name:
OnTime
The operating time since startup is saved in seconds in this register.
Data type
Value
UDINT
0 to 4,294,967,295
4.3.14.10.22.2 Startup counter
Name:
UpCounter
The number of restarts since startup is saved in this register.

4.3.14.10.22.3 Minimum operating temperature
Name:
MinTemp
The lowest transformer temperature [°C] since startup is saved in this register.
Data type
Value
Information
INT
-200 to 200
Resolution 1°C
4.3.14.10.22.4 Maximum operating temperature
Name:
MaxTemp
The highest transformer temperature [°C] since startup is saved in this register.
Data type

Resolution 1°C
4.3.14.10.23 Minimum cycle time
The minimum cycle time defines how far the bus cycle can be reduced without communication errors occurring.
It should be noted that very fast cycles decrease the idle time available for handling monitoring, diagnostics and
acyclic commands.
Minimum cycle time
200 µs
4.3.14.10.24 Minimum I/O update time
The minimum I/O update time defines how far the bus cycle can be reduced while still allowing an I/O update to
take place in each cycle.
Minimum I/O update time
Voltage and current sampling rate for calculation of effective value, power and energy
1 MHz
Derived values: RMS, power, energy, power factor, phase angle, frequency (mean values over 16 full waves)
Approx. 3 Hz
FFT on request (SR: 8 kHz)
2 Hz
