This example details how to configure a Schedule Based Preventative Maintenance Add On for regular tool calibration. 


For this example, the tool will be a Thermometer and an Internal Calibrations form will be scheduled to be started every month for five months, an External Calibrations form will be started in the sixth month, and this pattern repeated.


A Tool Registry process (the Asset process) captures information about the tool. Note a difference in this configuration that the Schedule Start field has a value. If a value is placed in this field, this is the date that the Schedule Based Preventative Maintenance Add On will use as its start date. The reason the configuration is different in this example is because you don't want to send out all your tools for calibration at the same time, which if you configured a start date on the Schedules process, all Calibration forms would be started on the same date. This configuration allows the user to stagger Calibration times by asset. 



A Calibration process captures the calibration data related to the Tool. 



A Schedules process defines the frequency Calibration forms are started in relation to an Asset form. 



The first row is the internal calibration schedule.  The second row is the external calibration schedule. 


Internal Calibration (the first row in the Task Schedule table)


Start: intentionally left blank because the start date comes from Tool Registry (asset process)

Frequency: Monthly - Internal calibrations patterns are evaluated on a monthly basis

Pattern: 5,1

Value

Position

Internal Calibration Pattern=5,1

5

1

The odd positions are considered On.  The scheduler will create 1 calibration form for each of the 5 months after (and including) the Start date.

1

2

The even positions are considered Off.  The scheduler will not create a calibration for the 6th month.



After the 6th month, the scheduler will start again at the first position of the pattern.



External Calibration (the second row in the Task Schedule table)


Start: intentionally left blank because the start date comes from Tool Registry (asset process)

Frequency: Monthly - Internal calibrations patterns are evaluated on a monthly basis

Pattern: 0,5,1,0


Value

Position

External Calibration Pattern=0,5,1,0

0

1

The odd positions are considered On and the value of the position is zero (0).  When the scheduler encounters a value of zero (0) it skips the instruction and moves to the next position; the position is ignored.

5

2

The even positions are considered Off and the scheduler will not create a calibration for these frequencies.  In this case the scheduler will not create any calibrations for 5 months.

1

3

The odd positions are considered On.  After 5 months of not creating a calibration form, the scheduler will create one calibration form for the 6th month.

0

4

The odd positions are considered On and the value of the position is zero (0).  When the scheduler encounters a value of zero (0) it skips the instruction and moves to the next position; the position is ignored.



After the 4th position (which is effectively ignored) the scheduler will start again at position 1.  In this case, position 1 will be ignored with position 2 being next in line (5 months on)
