5. Analogue input module CPX-4AE-T
Module parameters: Measuring unit and interference frequency suppression
Function no. 4828 + m * 64 + 6
Description The measuring unit for the temperature can be switched to either:
– °Centigrade or °Fahrenheit
The interference frequency suppression specifies the frequency at which power
units etc. are to be operated in order that interference resulting therefrom can be
suppressed.
– 50 Hz or 60 Hz
Bit Bit 3: Measuring unit for temperature
Bit 4: Interference frequency suppression
Values Bit 3: 0 = °C (presetting); 1 = °Fahrenheit
Bit 4: 0 = 50 Hz (presetting); 1 = 60 Hz
Comment – Converting temperature units:
