Parameter description analog input

Group diagnostics
You can generally enable and disable the diagnostics function of the device with this
parameter.
The "Fault" and "Parameter assignment error" diagnostics functions are always independent
of the group diagnostics.
Diagnostics: Missing 1L+
If you enable this parameter, the check for missing supply voltage is enabled.
Diagnostics: Short-circuit sensor supply
If you enable this parameter, a diagnostics event is generated if a short-circuit of the sensor
supply to ground is detected and the channel is enabled. The sensor supply is monitored for
connectors X1, X3, X5, and X7. No differentiation is made as to the connector where the
sensor short-circuit occurred.
Interference frequency suppression
With this parameter, you set the integration time of the device, based on the selected
interference frequency. Select the frequency of the supply voltage used. Interference
frequency suppression "Off" means 500 Hz, which corresponds to an integration time of 2
ms for a measurement channel.
Temperature unit
This parameter is used to select the unit in which the temperature is detected.
Reference temperature for TC
The reference temperature applies for all channels at which "Reference junction"
"Fix Ref. Temp." was selected. Information about the value range of the reference
temperature is available in the table Reference temperature for TC (Page 192).
