Allen Bradley PLC Ladder - Panel View - Cognex Camera - Yamaha SCARA
By Chris Elston
Here is an application where everything is sequenced in an Allen Bradley CompactLogix PLC using ladder logic. The Cognex camera is talking Ethernet/IP to the PLC, and the PLC is using Yamaha’s RCX340 AOIs (add-on instructions) to move the robot around. This vision guided application is very simple with the Cognex camera sending real world tool center data calibrated from the cameras Insight spreadsheet program directly via Ethernet/IP to the PLC tag registers. The source code includes the Cognex job file, Allen Bradley CompactLogix PLC version 24, Panel View 1000 version 10, and the Yamaha RCX340 backup .ALL file. A complete source code download shows how to integrated everything together.

• Calculation: WBGT=(.7*Tw)+(.3*T)
• Tw = T * arctan[0.151977 * (rh% + 8.313659)^(1/2)] + arctan(T + rh%) - arctan(rh% - 1.676331)+ 0.00391838 *(rh%)^(3/2) * arctan(0.023101 * rh%) - 4.686035
• Equipment Used
• Compactlogic Processor (1769-L30ER)
• Analog Input Card Configured for 4-20 mA (1769-IF4)
• Humidity/Temperature Transmitter (Omega Item#: HX303AC)

Assembly machine
By Todd B
I once programmed these many years ago. A guy from Allen Bradley setup the program and structure. I haven't programmed since and I am getting back into it. I thought the method he used to setup the different tabs, steps and description was rather unique at least for mechanical guy like me. Easy to follow once you got it down. Could someone open these a create a .pdf of them?

Micro Logix 1100 / Emerson EP
By simsrjr
This program was a fix for a Merrill Filler that lost one half of the screw. So because I could not get information to write from a Control Teqhniques Epsilon EP servo drive. I had the HMI controlling the SLC 500 and I would then write to the micrologix1100 which in turn sent speed acceleration, etc.. to the drive which controlled the screw.

Cop_5069_DigIO.ACD
By jstolaruk
I'm programming my first project with the 5069 series and the digital input and output points are not available from the modules in a condensed form. In response to the thread "Copy data from/to a 5069 digital module", I'm uploading what I'll be using to condense inputs and outputs into single elements.
The file is in v29, enjoy and look forward to seeing any improvements that can be made. Especially in the OB AOIs.

Paletizer
By marckTony
hello guys, I've got a project and i am not too familiar with the allen bradley PLCs. So I hope you guys can help me with some ideas. we have a palitazer in our class we have to modify the PLC's program and add an extra fisical bottons, pause botton(red botton) and continue botton(green botton)
some times the operator needs to get inside to the enclosure WHILE THE MACHINE IS IN AUTO MODE and that is why we need the stop botton, so the operator can push it and "pause" the machine in any moment. all the outputs and inputs should stay in their current state until the operator press the start/continue bottom, after this the machine should be able to continue the routine.
here is some info about the palletizer
http://bidonequipment.info/pdf%20files/FMC%20CORPORATION%20EZY-150%20Palletizer.pdf
I dont know if this is possible or not I've been studyng the ladder, but I could find the solution.
I atached the PLC program in this file, thanks you very much
we got the PLC Allen Bradley SLC 5/03

Thought i would put these in the sample code section since when i was searching i did not find much.
The mrplc_post is the micrologix 1400 program and the mrplc_post2 is the maples HMI5043T display program which was created with the maples easybuilder 5000 software.

Generic Sequencer
By OkiePC
This program is used to construct a sequencer with both input and output sequencing. The excel file is used to design the sequencer and includes features to update the user selectable files in a PLC using DDE. The PLC program sequences the inputs meaning that the input pattern for each step determines when the sequencer advances. A mask file is used for the inputs so that those that are irrelevant for a particular step can be ignored. This program does not use the classic sequencer instructions but uses MEQ and MOV instructions with indirect addressing instead. This leaves the end user more flexibility for controlling the step number.
Update r002: Added CLR instruction to the diagnostic word so that it does not hold "old data" as the sequencer advances.
EDIT: Added a beefed up version* for a real world machine (OK International 220 Servo bag inserter.) This program is not fully polished, I think the version here was after a few hours of refinement, and then stripping it down for speed. Today, I hit a full 17.5 bags per minute replacing logic that was running at 14.5 bags per minute. I ended up removing another input conditon for the seal bar timer, finding that it doesn't need to inhibit the opener from opening. I need to put in a discharge timer to keep the belt running long enough to send the last box out when finished even when the downstream is blocked, but continue to hold back the input clamps. it would be handy to cycle stop and have the machine empty itself too.
My main next goal on this particular machine, is to find out why the Ultra drive is not ready and homing quickly enough. I think my reset times are worse than the old logic! It seems I have to wait 5.5 seconds after the drive is ready before I can send it a successful home trigger. Today, I tried keeping logic power applied, and it did well until someone had to physically move this linear device and caused regeneration which triggered a non-recoverable (must power cycle)... E41...So, I can't cheat with two black wires unless I add a shunt or an output contactor to dodge this hard fault. The extra effort will be an amazing improvement in recovery times when they have to open the doors. Now it take almost en seconds sometimes to reset and then reset. I must be sequencing the output logic to the Ultra drive incorrectly,.but I have altered it several times with little improvement. There will be more trial and error with the wiring and perhaps a DB to get this right.
*The 2nd file includes a rate calculation (boxes per minute in this case) as well as a programmable minimum and fault timeout for each step, multiple modes (auto, manual, single step, bag only).
Known limitations: I have realized the need to add a macro button to the xls sheet which would read back the PLC sequencer data and populate the bit fields in the sheets. I also still need to lock the references so you can move the raw data without hosing up the references on other sheets. For use as-is, just don't drag the raw bit data or insert data, copying and pasting is fine to move steps forward and backward.
I also need to add to the excel sheet some columns for minimum time in step, and fault times so they can be edited from the workbook too.
