Output Pin Description

Output	Data type	Description
q_xEn	BOOL	TRUE: The function block is enabled. FALSE: The function block is disabled.
q_stMechClass	DutyRatingOut	Structure of mechanical class data
q_stLoadSpect	DutyRatingOut	Structure of load spectrum data
q_stRunTimeClass	DutyRatingOut	Structure of run time class data
q_xAlrm	BOOL	TRUE: Alarm detected. FALSE: No alarm is detected.
q_wAlrmId	WORD	Alarm status Range: 0...2

q_xEn

Status of the function block (enabled/disabled). In disabled state, the function block writes Dis to the elements of output structures and stops tracking the crane usage.

q_stMechClass, q_stLoadSpect, q_stRunTimeClass

Output structures of calculated mechanical class, load spectrum and run time class, respectively. The structures are of the same data type and contain text output STRING[8] calculated for the current day, last day, last seven days, last 30 days, and overall usage of the crane.

Mechanical class for last 7 and 31 days is calculated as an arithmetical average of stored values. Overall mechanical class is calculated using an exponential moving average. The value contains data from every day of past usage but recent usage is emphasized.

q_xAlrm

The output indicates that an alarm is detected (TRUE = an alarm is detected). Detailed information on the detected alarm can be found in the description of output q_wAlrmId.

q_wAlrmId

This output identifies the detected alarm.

Alarm bit	Description
bit 0	i_rLoadNom ≤0.0.
bit 1	i_rLoadAct is negative.
