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.

Ethernet Link Status
By Ken Roach
A Message instruction can be used to check the Ethernet link status of a 1756-ENBT or other ControlLogix family Ethernet module port to determine if there is a good Ethernet link.
This example shows how to send a CIP Generic Message to Class 0xF6 Instance 1 Attribute 2.
The applicable page from the EtherNet/IP Specification (www.odva.org) is included in the ZIP file. The program file was greated with RSLogix 5000 v15.

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.

Conveyor FIFO (first in first out) w/Reject
By Chris Elston
Classic example of a FIFO (First in First Out) Load and Unload.
Application was bottles coming down a conveyor system at a "variable" rate and sporadic. Sometime 10 bottles would be grouped together all in single file others they would be spaced out oneisy twoisy.
A photoeye was used in a vision cell up stream this photo triggered the vision system and loaded the FIFO at the same time.
A photoeye was placed downstream next to an air blow off nozzle. This created a "zone" at which you could load and unload the FIFO and keep track of bad bottle in-between your zone. Bottle QTY could vary between the vision photoeye and reject photoeye.
The vision system was triggered and part status was loaded into N7:0. A 1 means good part a 2 means bad part. The 1 or a 2 was loaded into a FIFO and placed into N7:1 at the reject air station. If the FIFO status equals 1 at reject it was allowed to pass if equal to 2 the air nozzle was turned on under a timed blow off.
This was a field installed retrofit project that involved a 10 point Micrologix 1000 that cost $72.00 4 Keyence Vision systems and 2 Banner EZ-Beam photoeyes. Cake work.

Assembly machine

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?
