6. Analogue input module CPX-4AE-TC
Module parameter: Unit of measurement for temperature
Function no. 4828 + m * 64 + 6;
Description The the unit of measurement for temperature values can be switched to either:
– ° Celsius
– ° Fahrenheit
Bit Bit 3: Measuring unit for temperature
Values 0 = °Celsius (presetting)
1 = °Fahrenheit
Note The setting for the unit of measurement refers to all temperature specifications,
e.g. to the recorded measured values, and also to limit values (see Tab. 6/17).
Limit values already saved are not automatically converted. After conversion of
the unit of measurement it is therefore necessary to convert the limit values and
re-enter them.
Converting temperature units:
– (x °C * 9/5) + 32 Z y °F
– (m °F - 32) * 5/9 Z n °C

Module parameter: Interference frequency suppression
Function no. 4828 + m * 64 + 6;
Description The module-internal interference frequency suppression has to be set to the
mains frequency of the power supply. Select the appropriate value:
– 50 Hz
– 60 Hz
Bit Bit 4: Interference frequency suppression
Values 0 = 50 Hz (presetting)
1 = 60 Hz
