Derating of the cable length due to temperature and clock frequency
INFORMATION

When using a CFX.. gateway, the temperature for calculating the derating must be assumed to be 5 K higher than expected in the control cabinet.
- Example:
- Expected control cabinet temperature: 45 °C
- Temperature for calculating the derating: 45 °C + 5 K = 50 °C
The following tables show the values for the derating of the cable length due to the temperature and clock frequency:
