Chapter 1: Getting Started
Rung #2
Place a normally open contact in the first position of Rung #2. This contact will be tied to
the Done bit of timer T1. Therefore, the name for this contact should be entered as “T1.
Done”. There should be no Create Nickname dialog as seen with the earlier normally open
contacts.
Lastly, you will need to add an Out coil to the end of Rung #2. Place the cursor at the end
of the rung and either select Out from the Ladder Palette Bar or just type “OUT” and select
the Out instruction from the drop down menu. Next, choose which bit will be tied to this
coil. Tie this coil to the physical output Y1 by typing “Y1” and click the check mark.
The ladder program should now look like the following. When either the T1_Start or
T1_Manual contact is energized, the timer will begin timing. When it times out, contact
T1_Done will energize and the output coil Y1 will turn on. Note that an END instruction
is not required.
