The module is currently performing a calibration procedure. This is a temporary and expected state, indicating that calibration is actively running and not a fault condition requiring troubleshooting of hardware. The module will return to normal operation upon completion.

This boolean tag indicates that the cold junction data for a specific channel (xx) is inaccurate and cannot be trusted for application use. A value of 1 signifies bad data, causing a fault. The tag automatically resets to 0 once the underlying condition is resolved.

This boolean tag indicates that field power is not present at the cold junction for channel (xx). A value of 1 means field power is absent, which can prevent cold junction compensation from operating correctly.

This boolean tag indicates that the cold junction wire is disconnected from channel (xx) or the Removable Terminal Block (RTB) is removed from the module. A value of 1 signifies an open wire condition. This prevents accurate cold junction temperature readings.

This boolean tag indicates that the cold junction temperature at channel (xx) is above the maximum of its operating range. A value of 1 means the channel data is above the absolute maximum threshold.

This boolean tag indicates that the cold junction data for a specific channel (xx) can be inaccurate, though the exact degree of inaccuracy is not known. A value of 1 means the data is uncertain. The tag automatically resets to 0 once the underlying condition is resolved.

This boolean tag indicates that the cold junction temperature at channel (xx) is below the minimum of its operating range. A value of 1 means the channel data is beneath the absolute minimum threshold.

This boolean tag indicates that channel data for channel (xx) is inaccurate and cannot be trusted for use in the application. A value of 1 means the data is bad, causing a fault. The tag automatically resets to 0 once the underlying condition is resolved.

This boolean tag indicates that field power is not present at channel (xx). Field power is typically provided through the SA power connector on the controller, EtherNet/IP adapter, or field potential distributor. A value of 1 means field power is absent.

This boolean tag indicates that channel (xx) is holding its output until the received data value is stable and within 0.1% of the full-scale range of the current data value. A value of 1 signifies that the channel is in a hold state.

This boolean tag indicates that the signal wire is disconnected from channel (xx) or the RTB is removed from the module. This condition is detected only when the channel is configured for current mode output. A value of 1 signifies a no-load condition.

This boolean tag indicates that the last value received for the channel (xx) output data value was not a valid number. A value of 1 means the data received was non-numeric, which can lead to incorrect output signals.

This boolean tag indicates that the signal wire is disconnected from channel (xx) or the Removable Terminal Block (RTB) is removed from the module. A value of 1 signifies an open wire condition. This prevents accurate input signal readings.

This boolean tag indicates that the module's temperature is higher than its operating limits. If the tag is 1 but a fault does not exist on the channel, it's an indication of operating conditions. If a fault exists, the channel may not be functioning correctly.

This boolean tag indicates that the channel (xx) data is above the overrange threshold for this channel. For example, when operating in the 4-20 mA output range, the overrange threshold is >21.0 mA, and an output signal of 21 mA would set this tag to 1.

This boolean tag indicates that a short circuit or overcurrent condition exists on channel (xx). This condition is detected only when the channel is configured for voltage mode output. A value of 1 signifies a short circuit or overcurrent.

This boolean tag indicates that the channel data for a specific channel (xx) can be inaccurate but the degree of inaccuracy is not known. A value of 1 means the data is uncertain. The tag automatically resets to 0 once the underlying condition is resolved.

This boolean tag indicates that the channel (xx) data is beneath the underrange threshold for this channel. For example, when operating in the 4-20 mA output range, the underrange threshold is <3.6 mA, and an output signal of 0 mA would set this tag to 1.

This boolean tag indicates if a connection to the owner-controller is running. A value of 1 means the module is not connected, potentially preventing proper operation. The module automatically sets this tag to 0 when connected and running.

This boolean tag indicates that one or more diagnostic conditions are currently active within the module. A value of 1 signifies an active diagnostic, which could be an Open Wire, Over Temperature, Field Power Off, or Underrange/Overrange condition. It recommends troubleshooting to determine the specific trigger.

An external condition has caused a fault on an input channel. This can manifest as an input signal that is overrange or underrange, a disconnected input wire (Open Wire), or an issue with the SA bus power. This indicates an issue with the input signal source, wiring, or auxiliary power for the input channel.

An external condition has caused a fault on an output channel. This can be a disconnected output wire (No Load), the module attempting to drive current exceeding its maximum channel level (Short Circuit), or an issue with the SA bus power. This indicates an issue with the wiring, load, or auxiliary power for the output channel.

This input tag, when set to 1, indicates that the data reported by channel xx is inaccurate and should not be used for control applications. This signifies a fundamental issue with data integrity for that specific channel, requiring immediate troubleshooting of the channel's setup and connections. The tag automatically resets to 0 once the underlying condition is removed.

This tag indicates that a wire is disconnected from input channel xx when operating in Current (mA) mode, specifically detected when the input signal falls below 100 μA. This condition concurrently sets the I.Chxx.Fault tag, indicating untrusted data, and requires physical inspection of the wiring. Open Wire Detection must be enabled in the module configuration.

This tag indicates that a wire is disconnected from input channel xx when operating in Voltage mode, detected when the input signal value reaches the full scale of the configured input range. This condition concurrently sets the I.Chxx.Fault tag, indicating untrusted data, and suggests a floating or open circuit voltage input. Open Wire Detection must be enabled in the module configuration.

This tag, when set to 1, indicates that the rate of change between input samples for channel xx has exceeded the configured Rate Alarm Limit (in Engineering Units per second). If the Rate Alarm latching feature is enabled, the alarm will remain active until manually unlatched, indicating an unexpected or excessively rapid change in the input signal.

This input tag, when set to 1, indicates that channel xx data might be inaccurate, but the degree of inaccuracy is unknown. While not a definitive fault, it suggests potential data integrity issues, and the data should generally not be used for control. The tag typically resets to 0 after a small delay once the condition is removed.

This fault indicates that an input wire has become disconnected from the module channel (xx). It occurs in various operating modes: Current, Voltage, RTD, and Thermocouple. When this fault is active, the I:Chxx.OpenWire tag is also set to 1, signifying the open circuit condition. This condition directly affects the accuracy and reliability of analog input measurements for the respective channel, potentially leading to incorrect process control actions.

The Module Status indicator is flashing green, indicating that the module is powered but does not have an active connection to the owner-controller. This can be caused by missing, incomplete, or incorrect module configuration, or if the module is inhibited.

The Module Status indicator is flashing red, which can signify several conditions: a module firmware update is in progress or failed, the device has experienced a recoverable fault, or a connection to the module has timed out. The specific cause needs to be determined via software diagnostics.

The Module Status indicator is steady red, indicating that the module has experienced a nonrecoverable fault. This fault condition prevents normal operation and cannot be cleared by typical troubleshooting steps.

The module (applies to both analog input and output modules) is not powered, or a connection from the controller to the module has not been established, or the specific channel is disabled. This prevents the module from operating as intended and requires investigation into power, communication, or configuration settings.

An issue internal to the module has occurred, such as a nonrecoverable fault, a calibration fault, or an over-temperature condition. This indicates a critical problem within the module hardware or firmware, affecting its operation and potentially requiring module replacement or environmental correction.
