We supply these programs as examples of how to apply the various instructions in our PLC’s. Please try to use these examples in their original form before modifying them for your particular application. We have had many calls claiming that the examples don't work and found that a mistake had been made when the example was re-entered by hand. The examples posted here have been run on equipment in our lab. If you are having difficulty with one of the examples check the following:

• Have changes been made and are they correct?
• Look at the title page for any special instructions.
• Is the example the only thing executing in the CPU and has the CPU gone from PROGRAM mode to RUN mode to allow the first scan logic to run?
• Does the CPU type and I/O match the example?

If you still have problems give us a call.

Instructions: The program you will download depends on which CPU you have. Find your CPU in the colored columns on the right, and click the WinZIP icon to download the right example program. The absence of an icon for a given CPU means that the example is not applicable for or will not work with that CPU.

EP-MISC-001	Ladder example code that will adjust the PLC's clock for Daylight Saving Time. Notes: For DirectLogic, only the 250/260/262, 350, 450/454 processors have a real time clock. The DL05 example will only work if you have the optional D0-01MC installed. The Basic CLICK PLCs do not have a real time clock.
EP-MISC-002	This file shows how the square root of a value between 1 and 9999 could be calculated. The resulting value has 2 implied decimal points. The square root is determined by using an iterative approximation, and therefore this algorithm requires a long time to execute.
EP-MISC-004	This example shows how to convert the current value of a timer or counter so that it appears to count down instead of up. This is useful for displays on an operator interface or for relational contacts to trigger an action at a low limit.
EP-MISC-005	This project uses two buttons pushed together for three seconds to latch an output.
EP-MISC-006	This is a simple example of how to use pointers.
EP-MISC-007	This program utilizes a pointer routine to store the accumulated time of T0 into successive double word V-memory locations beginning at V2000. Each time C0 changes from OFF to ON the accumulated time is loaded into the current memory location pointed to then the pointer location is incremented by 2 for a double word. This program is coded for the D2-250 Using Pointers it shows how to increment and move through a series of registers.
EP-MISC-008	This project will create a table of values generated by measuring the times an input is energized.

It also writes C20-C37 to the outputs on the slave. Slave project: This project can be used in conjunction with the master project to setup the slave to turn off its outputs if the master PLC stops communicating with it.
