Application Examples
Figure 19 - 1734-IB8S Module Properties – Input Configuration
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, as well as, supplies power to the OSSD
inputs. By setting it to Standard, you can programmatically turn these points
OFF and ON.
