Job Control

Checker 3G has eight 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 its

input lines.

You can assign a Job saved on a Checker to any Job slot using the Main Menu ►Job Control

screen on SensorView Teach Pendant or selecting Checker->Set up Job Control on the PC.

In the Job Control dialog box, each Job slot, from 0 through 7, 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, you must apply +24 VDC to the four

input lines that you use to load a Job from a Job slot. The JOB SELECT 0, JOB SELECT 1, and

JOB SELECT 2 lines specify the 3-bit Job slot number. You use the JOB CHANGE line 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 JOB SELECT 0 and

JOB SELECT 2 lines (101

binary = 5 decimal).

2 Apply a pulse (minimum

15 ms) to JOB CHANGE

line to load the Job in Job

Slot 5.

The example below shows how to load the Job in slot 5:
