DONE

Data_Type Default_Value Range Unit
BOOL - - -

Output DONE indicates that clock setting is completed. The output always has to be considered together with output ERR.

The following applies:

  • DONE = TRUE and ERR = FALSE:

    Clock setting is completed.

  • DONE = TRUE and ERR = TRUE:

    An error occurred during clock setting. The error number is indicated at output ERNO.

ERR

Data_Type Default_Value Range Unit
BOOL - - -

Output ERR indicates whether an error occurred during clock setting. This output always has to be considered together with output DONE. If DONE = TRUE and ERR = TRUE, an error occurred during Function Block processing. In this case, the error number can be read at output ERNO.

ERNO

Data_Type Default_Value Range Unit
WORD - - -

Output ERNO provides an error identifier if an invalid value has been applied to an input or if an error occurred during Function Block processing. ERNO always has to be considered together with the outputs DONE and ERR. The value at output ERNO is only valid if DONE is TRUE and ERR is TRUE. The error messages Error Messages of the Function Block Libraries encoding at output ERNO is explained at the beginning of the library description.

NUM_CYCLES

Data_Type Default_Value Range Unit
WORD - - -

Output NUM_CYCLES provides the current value of the CM574-RCOM cycle counter. This value is permanently updated as long as EN = TRUE. The cycle counter should be used to monitor the CM574-RCOM (life identifier).

NEW_TIME

Data_Type Default_Value Range Unit
BOOL - - -

Output NEW_TIME is set to TRUE for approx. 5 seconds, if a new RCOM time has been set using the RCOM_CLOCK Function Block. This output can be used to adjust a realtime clock to the time applied at HOUR_ACT, MIN_ACT and SEC_ACT.

HOUR_ACT

Data_Type Default_Value Range Unit
WORD - - -

Output HOUR_ACT indicates the hours component of the RCOM system time. The master can adjust the time using the RCOM_CLOCK Function Block.

MIN_ACT

Data_Type Default_Value Range Unit
WORD - - -

Output MIN_ACT indicates the minutes component of the RCOM system time. The master can adjust the time using the RCOM_CLOCK Function Block.

SEC_ACT

Data_Type Default_Value Range Unit
WORD - - -

Output SEC_ACT indicates the seconds component of the RCOM system time. The master can adjust the time using the RCOM_CLOCK Function Block.

NUM_EVENTS

Data_Type Default_Value Range Unit
WORD - - -

For RCOM slaves, output NUM_EVENTS indicates the number of events stored in the event queue. For the RCOM master, NUM_EVENTS is always zero.
