Table 54 - DSP Status
Description (if = 1)
Container value allows access to hidden tags. The hidden tags provide no user actionable information. The tags are
provided to assist device diagnostics only.
See the Assembly Object
If bits 0, 1, and 2 are 0, the DSP is ready. Anything else, the DSP is either starting up or changing configuration.
DSP Ready Status
If on recalling a configuration from update the DSP finds a CRC mismatch, the configuration is considered corrupt, the
module is set to its default configuration, and the bit is set.
Is briefly set during the module startup sequence. Otherwise indicates that the DSP has reset or that the auxiliary
communication processor configuration has failed.
DSP Reset
Indicates when the auxiliary processor board temperature is less than -20 °C (-4 °F) or greater than 70 °C (158 °F).
While the module rating is based on surrounding air temperature, depending on air flow, the board temperature can
exceed the surrounding air temperature by up to 25 °C (77 °F). This difference means that it is possible that the alarm
limit could be exceeded when the surrounding air temperature is as low as 45 °C (113 °F). Consequently, the
indication is considered only a warning.
Setpoint Multiplier control 0 and/or 1 is set. Associated Alarm limits are being multiplied.
Set when a configuration is received that includes changes to DSP functions. DSP functions include all functions
associated with signal conditioning, discrete measurements, alarms, and relays.
Cleared at powerup or when a new configuration is sent that does not change DSP parameters.
One or more voted alarms is inhibited (bypassed).
Any expansion module not present, responding, or reporting a configuration failure. If an expansion module is
missing or experiences a communication failure during configuration, then this bit remains set until the configuration
process completes successfully following a subsequent download.
An error or failure of one or more channels to calibrate. One or more channel calibration correction factors is too large
(abnormal deviation).
Any calibration timeout. Time-out occurs if the DSP does not receive the expected samples from the ADC. Likely
indicates another kind of HW error to a Calibration failure.
Main Module Relay is inhibited (bypassed). Inhibited relays are held in their non-alarm state.
Main Module Relay failed drive test.
Relay Drive Failure
DSP critical alarms loop cycle time >47 milliseconds. When set, the module can exhibit poor performance for tasks
other than alarm detection.
Loop Time Warning
A multiplexed personality is being executed. Measurements are not continuous.
A fault is detected on either of the main module speed inputs.
Speed Fault
