(We are not using it in this example)Ī more useful output bit for a counter would be a counter done bit, like in Allen Bradley PLC counter below.Īfter limit_switch_1 goes from disabled to enabled 10 times, the. The counter output on right labeled "Q" is a place you can put an output bit that indicates the counter is counting. In other words, a photo eye that detects each pallet released, increments the counter up. It is counted up (incremented by 1) with a photo eye pallet bit.

The Sort Height Basic is a Siemens PLC program example that comes with the Siemens simulation software bundle.
We renamed the Sort Height Basic program, adding the word "counter" to the end of its original name. So if things go south, you can always go back to original PLC program. Tip: Best practice is to first save a copy of the PLC program to be modified as a different name. You can click on Siemens PLC programming example above to enlarge. Shown below, is the Siemens counter number 107, programmed to reset if the operator’s reset pushbutton is pressed OR if the internal 'Counter Done' bit becomes true. You can see the current value of counter number 107 matches the displayed count via the binary integer output from Siemens PLC counter. As shown in picture above, in the Siemens simulation software, we have a counter function. Ok, lets pull back the curtain and see what controls this counter display on the operator control panel. You will also learn in the example that the operator can manually reset the counter to zero. The bottom photo eye on the safety light curtain detects each pallet passing by.

You will see us switch the Factory simulator to run mode and the counter starts counting pallets. The video above shows the factory simulation process we’ll use to explorer how the Siemens PLC counter drives the counter display. We promise when we create the PLC counter programming example part 2 video, we'll do a better production job. Also below are screen shots that are more clear than video so you can click on them to enlarge and study. So we offer the additional Counter PLC programming example content below to supplement the video.

Plus our first PLC programming example video using the Siemens PLC simulator came out a little blurry. The Siemens PLC programming tutorial - Counters video has a little repetition in it, but more wont hurt.
Repetition helps build retention and is often the difference between education and training.
