Chapter 7 Application Examples
Figure 22 shows the Test Output tab of the 1734-IB8S module properties.
In this example, Points 0 and 1 are set to Pulse Test as these points help check
the integrity of the contactors K1 and K2, to be sure they are off before the logic
program energizes the contactors.
Points 2 and 3 are set to Standard. Point 2 is the LOCK command. Point 3
applies power to the safety switch. By setting it to Standard, you can
programmatically turn these points OFF and ON, in case a nonrecoverable
fault occurs with the switch.
