We supply these programs as examples of how to apply the various instructionsin our PLC’s. Please try to use these examples in their original formbefore modifying them for your particular application. We have had many callsclaiming that the examples don't work and found that a mistake had been madewhen the example was re-entered by hand. The examples posted here have beenrun on equipment in our lab. If you are having difficulty with one of the examplescheck the following:. Have changes been made and are they correct?. Look at the title page for any special instructions.

Program Logic Model

Is the example the only thing executing in the CPU and has the CPU gone fromPROGRAM 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.Thank you - The AutomationDirect Technical Support TeamTHE INFORMATION PROVIDED IN AUTOMATIONDIRECT TECHNOTES IS PROVIDED 'AS IS' WITHOUT A GUARANTEEOF ANY KIND.

Find yourCPU in the colored columns on the right, and click the WinZIP iconto download the right example program. The absence of an icon for a given CPU means that the exampleis not applicable for or will not work with that CPU. General Examples305350405CLICKP3000Do-moreEP-MISC-001Simple program that adjusts the PLC clockto account for Daylight Saving Time. Can be used in DL250, 350, 450 andDL05 if the optional memory cartridge is installed.EP-MISC-002This file shows how the square root of a value between1 and 9999 could be calculated. The resulting value has 2 implied decimalpoints. The square root is determined by using an iterative approximation,and therefore this algorithm requires a long time to execute.EP-MISC-004This example shows how to convert the current value ofa timer or counter so that it appears to count down instead of up.

Thisis useful for displays on an operator interface or for relational contactsto trigger an action at a low limit.EP-MISC-005This project uses two buttons pushed together for threeseconds to latch an output.EP-MISC-006This is a simple example of how to use pointers.EP-MISC-007This program utilizes a pointer routine to store theaccumulated time of T0 into successive double word V-memory locations beginningat V2000. Each time C0 changes from OFF to ON the accumulated time is loadedinto the current memory location pointed to then the pointer location isincremented by 2 for a double word. This program is coded for the D2-250Using Pointers it shows how to increment and move through a series of registers.EP-MISC-008This project will create a table of values generatedby measuring the times an input is energized.EP-MISC-009This program shows how to implement a push-down stackin ladder using the MOV instruction.EP-MISC-010DL450 PLC Only. This program calculates the StandardDeviation on a Table of 10 BCD Double Words.
