For more information on field diagnostics conditions, see chapter 8.4
You find more details on the configuration options for field diagnostics in the following sections.
7.2 Input Configuration
Most device inputs are multifunctional inputs that can be used for different types of I/O signals.
Note
Analog Limit Values
You can configure Hi and Lo Maintenance Required and Out of Specification limits for analog
input values. If you do not want to use these limits, you can disable this functionality by entering
the following information in the configuration:
• For "low": <<<
• For "high": >>>
This combination of characters means +- infinite and disables the functionality.
7.2.1 Frequency/Binary Inputs
• Lead breakage and short circuit detection can be enabled and disabled.
• Use as frequency input: Use input as frequency input instead of binary input.
The following settings are only used in binary mode:
• Invert: Invert binary input value.
• Use fault state: If an error is detected, the input status remains "GOOD" instead of becom-
ing "BAD". Depending on the setting of "Fault state to value", the input value remains on
the last "GOOD" value or changes to the fault state value.
• Fault state to value: If enabled, the input value changes to the value of the "Fault state" bit
when an error is detected instead of remaining on the last "GOOD" value.
• Fault state: Fault state value used with "Fault state to value".
• Field Diag Out Of Specification: If this option is set, a logical 1 at the binary input triggers
an IO_TB Out-of-Specification condition.
• Field Diag Maintenance Required: If this option is set, a logical 1 at the binary input trig-
gers an IO_TB Maintenance-Required condition.
The following settings are only used in frequency mode:
• High Out of Specification: If the currently measured frequency value is higher than the
High-Out-of-Specification limit, the field diagnostics IO_TB–Out-of-Specification condi-
tion is triggered.
Description
Any bit in
IO_TB.FD_OOS_ACTIVE is
set when IO_TB has the target
mode "AUTO"
Any bit in IO_TB.FD_MR_AC-
TIVE is set when IO_TB has
the target mode "AUTO"
Any bit in IO_TB BINARY_ER-
RORS or ANALOG_ER-
RORS is set when IO_TB has
the target mode "AUTO"
