Configuration Errors - 1794-VHSC
Bits in the Status member are not named because they may have 3 different interpretations, depending on the module operating mode as described below.
The Status Word bit values and bit definitions depend on the state of the VHSC. There are three reporting states:
- Normal operation (Status LED-solid green)
- Incomplete, incorrect, or conflicting configuration (Status LED-flashing green)
- Hardware power up self-test error (Status LED-flashing red). Refer to1794-VHSC Hardware Power Up Self-Test Errorsfor more information.
The ConfigurationError member of the AB:1794_VHSC:I:0 module-defined data type reflects a change in its members values any time incomplete, incorrect, or conflicting configuration data is sent to the module. Use the table below to understand the reasons for module’s condition.
Important: | If the controller is in Run mode and a bad configuration is sent to the 1794-VHSC module, the error flags are set in the Fault word in the Input tags and the green OK LED on the module will blink On and Off. The module, however, will continue to run with its previous good data. To avoid confusing the monitoring application, no live data is returned to the Logix Designer application. |
Status (Bit Definitions) | Meaning in This Context | Status (Bit Definitions) | Description |
Fault.0 | Ch0Zinput | Fault.0 | Reserved Configuration or mode was set. |
Fault.1 | Ch0ZeroFrequencyDetect | Fault.1 | ZeroFrequency set, B Filter and A Filter were selected and no Filter Rate was specified, or multiple filters were selected (should not be enterable via HI, but possible via tags.) |
Fault.2 | Ch0StoredData2 | Fault.2 | A timebase was entered (in the Configuration Tag) that was not a multiple of 10, or the timebase is too large (>3000 ms, >3 sec) |
Fault.3 | Ch0StoredData3 | Fault.3 | A configuration requiring a timebase was selected and no gate interval was set or the gate interval is too large (> 3 sec) or the product of timebase and gate interval is too large (> 3 sec) |
Fault.4 | Ch1Zinput | Fault.4 | A rollover of zero was programmed through PWM was not selected or a rollover was programmed and PWM was selected, or the rollover is out of range (1 <= rollover <= 16,777,216) |
Fault.5 | Ch1ZeroFrequencyDetect | Fault.5 | The preset is out of range (0 <= preset <= 16,777,215) |
Fault.6 | Ch1StoredData6 | Fault.6 | A configuration requiring a scalar was selected, and no scalar was programmed or multiple scalars were selected |
Fault.7 | Ch1StoredData7 | Fault.7 | A tie has been connected to an unprogrammed window |
Fault.8 | Output0 | Fault.8 | Counter 0 window ON and OFF values are equal and not zero or Counter 0 Window ON and OFF value greater than 16,777,215 |
Fault.9 | Output1 | Fault.9 | Counter 1 window ON and OFF values are equal and not zero or Counter 1 Window ON and OFF value greater than 16,777,215 |
Fault.10 | Output2 | Fault.10 | N/A |
Fault.11 | Output3 | Fault.11 | |
Fault.12 | TestFail | Fault.12 | |
Fault.13 | NotReady | Fault.13 | |
Fault.14 | FieldPowerFault | Fault.14 | |
Fault.15 | ConfigurationError | Fault.15 | Incomplete, incorrect, or conflicting set of configuration parameters have been sent to the module. |
