Response of outputs to errors
The device makes a distinction between the output behavior "Alarm", "Warning" and "Error".
See the following table and
93, Section 9.2 "Diagnostic information on local display".
Certain problems can be assigned the "GOOD" status via FF communication, see Section 9.4.1.
9.6.1
Analog Input Block
If the Analog Input Block receives an input or simulation value with the status BAD, the
Analog Input Block uses the failsafe mode defined in the FSAFE_TYPE
1
parameter.
The following options are available by means of the FSAFE_TYPE parameter:
• Last Good Value
The last valid value is used for further processing with the status UNCERTAIN.
• Fail SafeValue
