I am a Canadian Red Seal Electrician, with over 35 years AB PLC experience. My apprenticeship was served in at a large sawmill site in BC, Canada. In the 2nd year of my apprenticeship in 1982, I was part of the crew that installed the first mini-PLC2 on site. From there our entire site was slowly changed from hardwired relay logic to AB PLC controls.
This channel is about how I test Allen Bradley/ Rockwell Automation PLC components CLogix/RS5000, PLC5 & SLC500 parts. Videos are done at my workbench, with actual components that I sell. Check back often as I will continue to post videos on how to test various AB PLC parts.
If you have questions on how to learn to be a PLC programmer - I would strongly suggest that you check out this website www.plcs.net - Clear and concise explanations about PLC programming - Link is below.
Hello Miguel: The UIC adapter can be switched between RS232 for the serial communication port or DH485 which is the other port. Even though it looks like an ethernet port it is not. Just about any USB to serial adapter will allow you to hook up to the 9 pin RS232 port. The biggest trick is to make sure you have the correct 9 pin cable. Thne do an auto configure in Linx and it should connect.
@@abplctestbench759 Thanks for your Response! Well I try with my USB Serial Adapter and a null-modem cable and the RSLinx never connect to the PLC, and the Autoconfigure always fail. The correct cable is a female to female DB9 with Pins 2 - 3; 3 - 2; and Straight 5? Thanks Again?
@@abplctestbench759 Another Question, Sir have experience with the DTAM plus Terminals? Is possible to upload from the terminal to my PC (I Have the DPS software) this terminal have Printer port RS-232, wich cable is needed to connect to the PC? Thanks!
@@MiguelGomez-rc7ou Sorry to take so long - been having PC problems all last week. Good except on each end you have to jumper: 1 to 6 and then it should work. If not let me know and I will do up a video showing the connections. Once you get it working on the 1 it will work on all of the devices you need.
@@abplctestbench759 Hope all problems has been solved!! OK, Maybe week I need to return to that CPU and DTAM terminal and will probe that config. Thanks!!!!
@@abplctestbench759 Great thanks a lot. I still have 3 units here to refurbish :) lmk when you need hmi spare parts. I am small german repair guy Siemens/Beckhoff/AB etc
I had the same issue with L81E, A10/C chassis and PB75/B power supply. Replaced every part in the configuration and issue was not resolved. Finally changed power supply to a few years old PB72/C and the power up fault was resolved. I’m bit confused as the datasheet indicates PB75/B supports both type B and C chassis. Anyways hope this will help someone
Hi been away for a few weeks on the road. Rockwell has multiple issues on this setup that they are not resolving or letting people know how to resolve. The 81x Error codes that keep popping up show how far down their quality has gone.

Hi: Been away for a couple of weeks. You should be able to by setting the trigger points in the module setup screens. Not something I have ever needed to try.
Hello Dale: I have been out and on the road for awhile. Your inquiry would be best asked at www.plcs.net/ - He has multiple training videos. My videos are the basics. Thank you
Hello: please explain your problem. Because of the number of scams on RU-vid I don't have an email contact posted. Once you tell me your problem I will see what we can do. It is currently Sunday here in Canada. Where are you? Thank you
Hello, I have a panel view plus 7, the bd9870 voltage regulator is burned out, it has fatal error 3a, can you explain to me what could have happened, thank you
Hi Michael: THE PVP7 overlays that come direct from the factory are some of the cheapest crap I have seen since in years. 3A Fatal error is when the touchscreen overlay is damaged and stuck to glass. It is a stuck button error and can be caused by any abrasion or pushing too hard on the screen. I had one the other day that I fixed that looked perfect, but still gave the error. A pin prick thru the plastic to the glass will give the error also. Burning out the power supply is a new one on me. Was this in an area of some fluid or somewhere similar?
I trying to get it to take but I don't see my Flex I/O in linx when I connect from the laptop to the unit. the switch has 011 on the front this was given to us from a different plant as a trainer but I not having much luck connecting. bootp is see it so can you please tell me where I'm going wrong. MAC:0000bc376f2d We also have a switch in the trainer, but I tried but ways Thanks Darren.
Hi: You don't say if it is a series A or B. I suspect it is a series A. Try watching my other video - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VSc628BpRSE.html
I fought a mass meter today on a Ctr8 that wouldn’t give any feedback on 2 channels. I swapped it with a channel that was working and the problem moved. How can i verify this channels are getting feedback
HI: Normally my experience if the problem moves it is the input device. Take a spare input device - disconnect the field device at the PLC and hook the spare up to the card. Then see if you have the readings from the new device. (If you don't get a reading from the new device then it is the module - replace it.) Reconnect the field device. Go to a junction box close to the field device - disconnect the field device and hook on you now known spare device. If you get the readings at that point it is a safe bet that the original field device is dead. This is the standard 'divide and conquer' technique.
@@abplctestbench759 we had a short on a machine frame and had several devices get fried. What’s strange about this one card is it has 4 devices on it and we originally lost 3/4. We replaced them now 1/3 doesn’t work. We moved that one to a another channel and it didn’t work there either.
@@joew4202 Hi: Still sounds like you have bad field wiring or devices to me. Without being there it is really hard to guess from my end. (You can buy me a plane ticket and I can come for a visit🤣 to see if I can help)
In Canada from Monitech Industrial in Ontario. They also have a branch in Florida. There are other sources if you look hard enough. Some better than others.
Hello Fidel: Sorry for the delayed reply. I do NOT have any software to sell. It is illegal for me to sell and Rockwell software. There is a group of Rockwell lawyers waiting for me to do that so they can sue me. You would have to have someone sign over their license to you in order to get a copy. Maybe one of the other subscribers has a copy they can lend to you, but I can't because of legal threats from Rockwell. I am sorry that I can not assist you with the software.
What are the white/greenish trays that come with these terminal blocks? Looks like 8 tabs and 8 hooks/clips. Can't for the life of me figure out what they're for. Never seen any of our other slots use them.
Hi: Another bad idea from AB. These are supposed to be like the old style Keying bands that used to come with PLC5 chassis. They were responsible for a lot of damage to chassis and modules. You can set them up in a configuration of your choice to make sure the correct module is inserted into the correct wiring arm. A nice idea, but no idea if anyone uses them and AB does not give any guidance about using them. Recycle bin is best location IMO.
Hi BigTr: The longer the l8x is in service, the more problems seem to be showing up! Rockwell keeps doing firmware changes and screaming like kids about how everyone has to buy their software at insane prices, but not putting out a higher quality product. Each generation of Clogix processor has increased the processor speed 10x each time. But is it necessary? A super high speed processor is still not going to make your waste system in the basement work any faster or better. I still have customers very happily running SLC & PLC5 and it just keeps plugging along doing what it was designed to do.
Hello TB: Which Flex I/O modules are you worried about? There are many of them and all are current. Can you be more specific in your question? I have a number of videos on my channel that use the 1794 modules. ru-vid.com/group/PLApJy6_fcuvi_kx1MeMJjYus6rphDwVma You can also check the Rockwell site for product lifecycle status list - www.rockwellautomation.com/en-us/support/product/product-compatibility-migration/product-lifecycle-status.html
Hi: If you look close on each one there is a part number on there. No idea if AB sells them as I am blacklisted from buying from AB because I sell parts that are experienced. I ended up getting a guy to make on a 3D printer. In bulk they cost me $45 (CDN) each to get made. The option is to get some SLC500 chassis and strip them out of there. They are exactly the same size and better quality using the grey plastic compared to the cheap black plastic that they used in Clogix. The Clogix footprint is based on the SLC footprint. If you look at the screw holes in the chassis they are exactly the same. Hope this helps.
@@abplctestbench759 Thanks for answering my questions that actually helps out a lot. I think I’m going to buy a 3D printer and print them off. I have a feeling Allen Bradley doesn’t sell them. I tried looking at some distributors but they all said they would had to get back to me. lately a lot of your videos have been a great help to me, so thank you for that as well.
I have had this on 3 processors. Terrible situation, we brought Rockwell for their reliability and responsibility. Both are badly lacking. I am now moving to use Japanese and Chinese plc products and so far reliability has been perfect.
HI Tony: I have to agree with you on the lower quality of the product they are putting out in the last 10 years. What was an industry standard is getting to be an industry joke. The original PLC5 / 1771 structure was designed by old school Rockwell engineers and built to US MIL Spec - MTBF design was 80 years. Lots of it still running. The new stuff is designed to commercial specs and will normally last around 10 years.
Hi Taryn: Glad you were able to get some value out of my videos. As I have mentioned before the PLC5 generation of processors were designed by an older generation of designers. They were also built to US MIL SPEC and a have a MTBF of 80 years. The processor I used in this video has a date code of 1992 and I had just replaced the channel 1 communication port. It had blown up and there was carbon everywhere. But a quick changeout and away it goes for another 20 to 40 years. I think there will be lots of these in service long after I have turned to dust.☺
hello sir , I was wondering if i can upgrade sd ram and cf card of allen bradley by other sd ram and cf card but not alllen bradley but its out cost around 50$ and in ab cost 800$ so am asking it is possible
Hello: The CF card is formatted with the operating system and the RAM chip matches the card. You should be able to pickup a set of CF & Ram from ebay or similar online market place in your country for a lower price than Rockwell dealers want. Once you have made sure that the 'new' CF card has the correct version of F/W to match your running program, just reload your program on to the new card. Sorry I can't help any more than that. Thank you for the question.
“Pktx rio adapter driver detected block transfer size mismatch for BT1 (rack:1(oct.) slot:8) Driver*” Any idea what to do about this message on my PV+? I have tried what is written in the knowledge base but that didn’t change anything. I have also tried two separate HMI.
HI: I have never seen that error. Suspect that you are using this on a PLC5? Possibly change out the RN6 communication card that is mounted on the logic module. The RN6 contains a standard 1784-PKTX communication card that plugs into the logic module. They can be set up for DH+ - RIO - DH485 for communication with PLC5 & SLC processors.
@@abplctestbench759 Thanks, yes that’s correct, PLC 5. The PanelView is connected to a 1771-ASB from the RN6. I have also tried two separate PV+ units. Both give the same error.
Hi:@@MrExtremehustler Not sure what to suggest then. Possibly check your program backups compared to your running file to see if anyone changed a parameter in the block transfers for the read and write to the PV. Is there data being written into the BT file area that is overwriting something it should not. Also is there a DH+ network and maybe someone is writing to your PV from another station? The only other possibility I might suggest is changing out the logic module and downloading a backup file to it. Not the file running on the PV you are having trouble with.
Have you ever had a chassis with dead spots? We have a 1756-A17 and a couple of he 1756-OF8 cards had their RTNs stop having continuity to the chassis ground. We have had 2 OF8 side by side with their RTNs functioning differently. Card replacement did not resolve the issue, so we are thinking its the chassis.
I have seen a couple of bad ones for sure. Because of how cheaply they designed the system it is possible for thin pieces of metal to get behind the backplane and then short out pins. I would start by taking the chassis apart on a clean bench and see if anything conductive comes out when you have dismantled it. The same with where the cards plug into the headers. They are not sealed on the bottom so there is a possibility of shorting material there. Also confirm all of your grounding from the power supplies and the chassis. All grounds used in the system must be tied to a common grounding point. Hope this helps.
Hello Israel - I do not have a copy that I can sell or give away. Even though AB / Rockwell no longer sells or supports the software they still own it and guard it like a mad dog. I have been warned that the Rockwell lawyers are laying in wait for me to sell software so they can shut me down. So I do not sell or trade in any software. If someone else has a copy that they can give you hopefully they contact you after seeing this post. Bruce
Hi Greg: From what I read in the documentation - a percision resistor is required to do this calibration on these cards. I asked multiple supply sources and no one could supply me with one about 6 months ago when I looked for them. The software will step you thru the calibration but the external resistor is required before you start. I will find the value and post here in the answers tomorrow. If you have a source I would like to get some for my stock! Thank you for asking.
Found this today in the Analog calibration manual: From reading thru the manual you need a mV voltage calibrator source. I don't currently have one and not sure of the prices, but suspect that $1000 or more is not out of line. Cut and paste from manual below. -------------------------- Calibrating the 1756-IT6I or 1756-IT6I2 This module only calibrates in millivolts. You can calibrate the module to either a -12…+30 mV range or -12…+78 mV range, depending upon your specific application.
Hello Sir, I had the same problem with 3 brand new series C 1500 screens, however, I fix the problem with just a firmware update. I used RP1 logic modules on those screens and after the firmware update didn't show any errors. The FW version I used was 5.10.16UP
The wiring diagrams and documentation is on the Rockwell website. I suggest you go there and download the document for the module . www.rockwellautomation.com/search/ra-en-US;keyword=1794-IE12;startIndex=0;activeTab=Literature;spellingCorrect=true;facets=doc_type_full_s%253A%2528%2522Installation%2520Instructions%2522%2529;languages=en;locales=en_GLOBAL,en-US;sort=bma;isPLS=false;sessionID=7d520837-6fe7-6066-20ff-de0ddee07dab;deepLinking=false
Hi, I have several AB PLC's mostly SLC500 and 1000"s and have RS Logix 500 and 5000. I also have the 1771 with a 1785 5/40 Processor and a 1785 5/20. I and trying to find RS logix 5 demo or evaluation copy just to get this this this running and I have loads of card for it from analog, discrete, digital and many more it has the full size back plane I forget how many slots, I go it put up now but would love to fire it up and see what it does. I cannot find it anywhere other than from Rockwell Automation and can't even get my account setup with them anyway for some reason but don"t have the thousands of dollars for it. Is there a demo version of this available?
Hi Marshal: There used to be demo versions but Rockwell is hard set on trying to kill off the PLC5 systems. Last I heard is that they have removed all support for it and if you really want a copy it is well north of $20K for a 1 year license. There are none on ebay that I know of because of Rockwell threatening to sue ebay over copywrite. Because of threats of being sued I have no idea where I can suggest that you go and I do not have any demo's left that work. If someone has a copy that they are no longer using and have the key disk for it that will be your best bet. Sorry I can't be of any help on software but Rockwell has it tied up in a steel drum and welded shut. Hopefully someone can get ahold of you thru your website with an offer.
Hello: Without having it in hand I can only guess. I would suspect that the touchscreen is damaged and needs to be replaced. The touchscreen overlay is made of a plastic and depending upon the age may have an electrical grid in it to work as buttons for the screen You would have to send it out for repair or get an exchange unit. If you have the parts in hand it is a bit of work to rebuild, but can be done if you have the experience.
@@abplctestbench759 I think not a touch screen problem..becaz I swapped logic module from another hmi ...that time hmi was on mode...so what is the pbm in logic board ...
This is probably a power supply issue. I had the same problem with a PB75 + L81E. the same PLC worked well on another chassis so I figured out it was not the fault of the PLC. After replacing the bad PB75 with a different power supply unit, everything worked well.
Hi I am trying to troubleshoot a Panel view Plus 1000, but when powered the screen does not show anything, and The Fault LED is blinking, according to the manual this means it is a recoverable fault. I suspect it does not go past the initial boot. Any ideas, or do you have a contact I could reach out to you to better explain?
HI Bart: I would suspect that the CCFL is burnt out and not having a picture to look at possibly a damaged overlay causing a stuck button error. Since the PVP6 is a plug and play item, I would start by moving the logic module to another panelview if you have it to see if the problem moves with the logic module. No idea where on the planet you are - I am in BC Canada. Normally I can turn these around in a day as I have the parts in hand to fix them at a reasonable price.

Can I ask you a PLC-5 question? I am running Allen Bradley 6200 software and I was curious how to back up what's in the PLC. This video is a very good source of reference.
Hi Patrick: (Curious as to what country you are in.) I have never actually used the 6200 software. Suspect that you may be almost the last person on the planet to use it☺ That being said there should be a save program option in the software that allows you to download to the PC and save on disk. Not having a copy of it I can't be a lot of help, but on PLCS.net there is a few discussions about it. Start with this one and then if all else fails sign up and ask a question.
