Advanced Diagnostics
Cabinet I/O
• High Maintenance Required: If the currently measured frequency value is higher than the
High-Maintenance–Required limit, the field diagnostics IO_TB–Maintenance–Required
condition is triggered.
• Low Maintenance Required: Like High Maintenance Required, but for measured fre -
quency lower than the Low–Maintenance–Required value.
• Low Maintenance Required: Like High Maintenance Required, but for measured fre -
quency lower than the Low–Maintenance–Required value.
• Hysteresis: In order to avoid the flickering of diagnostics, a hysteresis value can be config -
ured.
7.2.2 Binary Inputs
• Lead breakage and short circuit detection can be enabled and disabled.
• 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.
7.2.3 Temperature/Binary Inputs
• Lead breakage and short circuit detection can be enabled and disabled.
• Use as binary input: Use input as binary input instead of temperature 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 temperature mode:
• High Out of Specification: If the currently measured temperature value is higher than
High-Out-of-Specification limit, the field diagnostics IO_TB-Out-of-Specification condition
is triggered.
• High Maintenance Required: If the currently measured temperature value is higher than
High-Maintenance-Required limit, the field diagnostics IO_TB-Maintenance-Required
condition is triggered.
• Low Maintenance Required: Like High Maintenance Required, but for measured tempera -
ture lower than Low-Maintenance-Required value.
