Allen-Bradley Compact 5000 Digital I/O Modules
38 fault codes documented
CIP Sync Master Timeout
This boolean tag indicates that the module was previously synchronized with an IEEE 1588 master clock, but synchronization has been lost due to a timeout. A tag value of '1' means the module is now using its local clock and may drift from the last known synchronized time, potentially affecting time-critical operations.
Owner-Controller Connection Fault
This module-wide fault indicates that the owner-controller has lost its communication connection to the module. This condition affects all channels simultaneously and can be caused by network issues or a deliberate module inhibition. The tag provides module-wide data.
Module Critical Temperature
This diagnostic indicates that the module is above its critical temperature limit, representing a more severe thermal condition than 'OverTemperature'. This condition can lead to immediate shutdown, module malfunction, and 'Uncertain' data quality, with a high risk of permanent damage. The tag automatically resets to 0 when the condition is removed.
One or More Module Diagnostics Active
This boolean tag indicates that one or more diagnostic conditions are active or a prognostic threshold has been reached on the module. A tag value of '1' means further investigation is required to identify the specific diagnostic causing the alert on a channel or the module itself.
Dual Channel Fault
This diagnostic indicates a fault is present in a dual-channel input or output configuration. This type of fault suggests an inconsistency, discrepancy, or failure across redundant channels, typically found in safety-related applications.
General Data Inaccuracy Fault
This fault indicates that reported channel or counter data is inaccurate and cannot be trusted for use in the application. When the tag is set to 1, the data should not be used for control. The fault tag automatically resets to 0 once the underlying condition is removed.
Field Power Off Condition
This diagnostic indicates a field power off condition exists on the module or a specific test point. It signifies a loss of external power supplied to the module's I/O terminals, which powers the connected field devices. The tag automatically resets to 0 when the condition is removed.
Faults Present in Undisplayed Group Channels
The Group A or Group B indicator is flashing red, signifying that I/O status is NOT currently displayed for this group of channels, but at least one fault exists on channels within this group. This serves as an alert that a fault is present in a non-active channel group.
Faults Present in Displayed Group Channels
The Group A or Group B indicator is flashing red and yellow, indicating that I/O status is currently displayed for that group of channels and at least one fault condition exists within those channels. This visually alerts the technician to a fault within the active group.
I/O Status Not Displayed for Group
The Group A or Group B indicator is off, meaning the I/O status indicators are currently not showing the status for that specific group of channels. This is not necessarily a fault but rather a display state of the module.
Safety Output Point Short Circuit Tag Active
This tag indicates that a short circuit has been detected on a Safety Output point (Ptxx). This can occur when the output is shorted to 24V DC, to ground, or between output points in a pair. When active, the module faults and turns off the affected output.
Safety Output Internal Module Fault Active
This diagnostic indicates an internal fault within the safety output module itself, affecting one or more output points. It typically occurs in combination with an I.Ptxx.Fault tag, rendering the output data unreliable and requiring attention.
Internal Module Fault
This diagnostic indicates that one or more internal diagnostics have found a fault within the product (module). This typically points to a hardware failure, firmware issue, or other internal malfunction of the module. If the problem persists, the module may need replacement.
Controller Connection Issue or Validator Not Complete
The Module Status Indicator (MOD) flashes green when there is no established connection between the module and its owner-controller. For Compact 5000 safety I/O modules, this can also mean the Validator has not completed an initial Time Coordination exchange.
Module Recoverable Fault / Firmware Update / Connection Timeout
The Module Status Indicator (MOD) flashes red, indicating one of several conditions: a module firmware update in progress, a failed firmware update attempt, a recoverable fault, or a connection timeout to the module. Module operation may be interrupted.
UNID Not Commissioned (Safety I/O)
For Compact 5000 safety I/O modules only, a flashing red and green Module Status Indicator (MOD) signifies that the Unique Network ID (UNID) has not been commissioned in the module. This is a critical prerequisite for safety module operation.
Module Power Not Applied
The Module Status Indicator (MOD) is off, indicating that power is not supplied to the Compact 5000 digital I/O module or the module is not properly installed. The module is not operational in this state.
Module Nonrecoverable Fault
The Module Status Indicator (MOD) shows a steady red, signifying that the Compact 5000 digital I/O module has experienced a nonrecoverable internal fault. This type of fault typically indicates a permanent hardware issue that cannot be cleared by typical resets.
Muting Lamp Fault (Safety Modules)
This diagnostic is triggered on a 5069-IB8S or 5069-IB8SK module's test output point. It occurs under specific conditions related to muting lamp operation, typically when a short circuit is detected while the test output is configured for Muting Lamp mode and commanded ON. The I/O Status Indicator will flash red.
No Load Condition
This condition exists when an output is commanded ON but no load current is detected, or the load device is disconnected. It is a diagnostic for standard output modules and can trigger a general 'Fault' tag. The tag automatically resets to 0 when the condition is removed.
Module Over Temperature
This diagnostic indicates that the module is operating at a temperature higher than its rated operating limits. This condition can lead to reduced module performance, an 'Uncertain' data quality tag, and potential long-term damage if not addressed. The tag automatically resets to 0 when the condition is removed.
Output Overload Condition
This diagnostic indicates an overload condition exists on the module, meaning the module's output current limit for a specific point has been exceeded. This can occur if the connected load draws more current than the module is rated to supply. The tag automatically resets to 0 when the condition is removed.
Safety Output Overload Fault Active
This diagnostic indicates an overload condition on a safety output point Ptxx. When an output is overloaded, the module detects this, sets the Overload Fault diagnostic, and also the I.Ptxx.Fault tag, rendering the output data untrustworthy and turning off the output.
Channel Data Inaccurate or Faulted
This boolean tag indicates that the channel data for Ptxx (either input or output) is inaccurate and cannot be trusted for use in the application. A tag value of '1' signifies bad data or a faulted condition. For safety modules, this can also occur if the channel is configured as 'Not Used'.
Channel Field Power Loss
This boolean tag indicates that a field power loss condition exists on the channel Ptxx. A tag value of '1' signifies that the external 24V DC field power supply for the channel is not present or has failed, disrupting channel operation.
Output No Load Fault
This boolean tag indicates a 'no load' fault condition for an output point. A tag value of '1' signifies that the signal wire has been disconnected from one of its terminals or the Removable Terminal Block (RTB) has been removed from the module, or no load current is detected.
Safety Channel Bad Status
This boolean tag indicates the operational status of the safety channel Ptxx. A tag value of '0' means the channel status is 'Bad,' which causes a fault. This is a general indicator of a channel issue requiring further investigation.
Channel Data Uncertain / Operating Temperature Out of Range
This boolean tag indicates that the channel data for Ptxx might be inaccurate, though the degree of inaccuracy is unknown. A tag value of '1' is set when the module has reached a critical operating temperature or is operating higher than the acceptable temperature range. For standard modules, it can also indicate data under manual or override control.
Safety Output Short Circuit Diagnostic Active
A diagnostic value of '1' indicates a general short circuit condition has been detected on a safety output. This can occur due to a short to 24V DC, ground, or between output points, causing the module to fault and turn off the output.
Safety Output Short Circuit to Ground Diagnostic Active
This diagnostic indicates a short circuit specifically from a safety output point to ground. When detected, the module faults and turns off the output to ensure a safe state.
Output Short Circuit/Overcurrent
This diagnostic indicates an output short circuit or overcurrent fault condition exists on an output point. For 5069-IB8S/IB8SK modules, this protection prevents damage to test outputs. When detected, the output faults and turns off, and the I/O Status Indicator flashes red.
Short Circuit to Ground
This diagnostic indicates that a short circuit to ground condition exists on an output point. This means the output wiring or the connected load has inadvertently made contact with the protective earth ground or a grounded enclosure. The tag automatically resets to 0 when the condition is removed.
Safety Test Output Data Inaccurate or Faulted
This boolean tag indicates that the data for a safety test output Testxx is inaccurate and cannot be trusted, or the channel is set to 'Not Used'. A tag value of '1' signifies bad data or a fault. If a short circuit is detected in Pulse Test or Power Supply mode, the output cannot be set to a safe state.
Test Channel Field Power Loss
This boolean tag indicates that a field power loss condition exists on the test channel Testxx. A tag value of '1' signifies that the external 24V DC field power supply for the test channel is not present or has failed, disrupting its operation.
Safety Test Output Short Circuit Fault
This boolean tag indicates that a short circuit has been detected on the safety test output Testxx. A tag value of '1' means a short circuit is present, and if the output is in Pulse Test or Power Supply mode, it may not be able to be set to a safe state.
Safety Test Channel Fault Status
This boolean tag indicates the operational status of the safety test channel Testxx. A tag value of '0' means the channel status is 'Fault,' indicating a problem with the test output. This is a general indicator of a test channel issue requiring further investigation.
Test Channel Data Uncertain / Operating Temperature Out of Range
This boolean tag indicates that the data for a test channel Testxx might be inaccurate, with an unknown degree of inaccuracy. A tag value of '1' is set when the module has reached a critical operating temperature or is operating higher than the acceptable temperature range.
Uncertain Data Quality Fault
This fault indicates that reported channel or counter data can be inaccurate, but the degree of inaccuracy is unknown. It suggests the data is imperfect and should be treated with caution, as it may not be suitable for control. The tag automatically resets to 0 once the underlying condition is removed.
