FC3 Counter Demo
By pop29684
This logic demonstrates the construction and cascading of counters that count from 0 to 9. This logic also illustrates the construction of counters that count from 1 to 10 (not useful for cascading). The difference is mainly in the comparators used to reset the counters. There is one small additional detail. Can you find it?

FC2 Toggle a bit
By pop29684
This logic demonstrates how to use a condition to toggle a bit. Any bitlevel condition may be used such as I, O, M, C, T, DB. Only two rungs of logic are required.

FC1 Two hand anti tie down
By pop29684
Logic takes two inputs (I0.0, I0.1), debounces each (T0, T1), looks for actuation during a timed period (T2), and provides validation (M20.0). This logic is not designed, nor intended, to replace the use of any OSHA required twohand safety control relay. It is provided for the sole purpose of it's educational value.

Range_Fnc
By Bryll
I sometimes need to scale an analog value, so I had to do a function to better suit my needs than Siemes "Scale" function.
It has 5 inputs, all in integer format.
_In  The value to be scaled
_In_Min  Lowest value of the "_In" signal.
_In_Max  Highest value of the "_In" signal.
_Out_Min  Lowest allowed value of the scaled output.
_Out_Max  Highest allowed value of the scaled output.
The output "_Out" is the calculated value in integer format.
Edit.
It's saved as a global library.

Dip paint
By bapi
This is a simple program to paint an object while the object is transferred from Station A to station C. The painting occurs in station B where the object to be painted is stopped and dipped in paint and the moves further to C. From C the transport system comes back to A without stopping on its return path at B.

drill machine
By bapi
This is a simple program where the drill arm moves down for the drill and the Drill motor starts as well. The drill arm stops after reaching the bottom level but the drill motor continues for a few seconds to ensure a good drill and then stops. Now the Drill arm moves up again and then reaches the top position and starts the cycle again.It is aslo ensured that the Drill arm is always at the top before the operation starts or if the drill operation is stopped in midway.
If you have any doubts or suggestions please feel free to comment.

Daylight Savings Time for S7200
By Crossbow
This is a quick sample program to demonstrate how to make the PLC adjust the clock for daylight savings time automatically. It's done with an S7200 but the logic sould be similar for any PLC from any vendor.
