Job Control
Requires the I/O Module.
Checker has 16 Job slots. You can assign saved Checker Jobs to Job slots,
then load them while Checker is running by sending Job Select and Job
Change signals to Checker through the I/O Module.
You can assign a Job saved on a Checker to any Job slot by selecting
Checker->Set up Job Control. In the Job Control dialog box, each Job
slot, from 0 through 15, has a menu that you use to specify the Job. You can
specify the same Job for multiple slots.
To load a Job from a Job slot while Checker is in Run mode, Checker must
be connected to the Checker I/O Module. The I/O Module has ve input lines
that you use to load a Job from a Job slot. Lines INPUT 2, 3, 4, and 5 specify
the 4-bit Job slot number. (INPUT 2 is bit 0, INPUT 5 is bit 3), and you use
INPUT 6 to load the Job.
Checker indicates that a Job Change succeeded by ashing its lights twice
quickly. A failed Job Change is indicated by three slow ashes. You can also
congure a Checker output line to signal when a Job Change succeeds or
fails.
The Job Control dialog box also lets you select the Boot Job (the Job
Checker runs when it is restarted after a power cycle in Run mode).

1 Raise INPUT 2 and INPUT 4 lines (0101 binary = 5 decimal).
2 Apply a pulse (minimum 10 ms) to INPUT 6 to load the Job in Job Slot 5.
The example below shows how to load the Job in slot 5:
