Table 2: Setting of diagnostic cases to be signalled (2-wire operation)
- Setting [drEd] = ON provides maximum availability since the transmission of the
measured temperature value is only interrupted for the diagnostic message in diagnostic
cases of category "failure"�
- Setting [drEd] = OFF provides maximum reliability of error detection since a diagnostic
message is provided for every diagnostic case�
To signal a diagnostic case the transfer of the measured temperature data is
interrupted and provided by the following analogue signal depending on the
setting of [FOU]:
[FOU2] = On: 21�5 mA
[FOU2] = OFF: 3�5 mA
In the event of undervoltage (diagnostic case 6 → 5.3.3) no diagnostic
message is provided in 2-wire operation�
5.3.5 Diagnostic function in 3-wire operation
In 3-wire operation the analogue output OUT2 is used for temperature
measurement and diagnostics� In addition a switching output is used via OUT1 for
diagnostics�
When the IO-Link interface is used, all diagnostic cases are always
provided via OUT1� In addition, a signal is provided that corresponds to the
behaviour of the physical switching output�
With [drEd] the diagnostic cases to be signalled can be set via the current output:
