Hello: Devicenet is no longer supported by Rockwell or anyone else. I used it for a bit while I was working in the sawmill, but that was it. It was a system that was prone to failures and had way too many quirks. Nothing I can do for training and suggest your facility get rid of it as soon as you can.

@ thanks. Please can you train me in plc programming?

@@Nicofish2023 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

Hi: You are welcome - I hope my videos assist in understanding AB PLC's.

Hi: There are 16 tiny little relays in there and you don't really want a heavy load on them. Personally I would not put more than 1/4 to 1/2 amp load at max on any channel regardless of the voltage.

Hi again: YES - I would keep the processor power supply and communication power supplies separate from any field devices power. AC or DC. High swings to the incoming power supply can cause the power supply to malfunction. It can also clear the memory and fault the processor. This is exactly the same scenario that happens with the SLC500.

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!!!!

HI: The key is the same one that is used in PLC5 processors. Simply take it to any locksmith and they can copy it for you. Nothing special about it.

@@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

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.

Thanks for finding this tip. Hope it helps someone else also.

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 UA-cam 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

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?

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 - ua-cam.com/video/VSc628BpRSE/v-deo.html

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.

You are very welcome. Hope that the information is helpful.

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. ua-cam.com/play/PLApJy6_fcuvi_kx1MeMJjYus6rphDwVma.html 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.

@@abplctestbench759 Thanks for answering my questions . It helps out a lot.

@@kimberlyclark955 Your welcome - I have some in stock if you need a couple.

Hello: I am not quite sure what you are asking. Can you please explain a little more what you are looking for. Thankyou

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: 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.

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.

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

@@abplctestbench759 thank you!

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.

Hi: You are very welcome.

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.

Yeah I was afraid of that. Well, Thanks very much for your help and your videos are great. Thanks again and keep up the great work.@@abplctestbench759

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 ...

@@srinathan8494 - Hi: Logic boards have been known to die. You need to get a replacement or send it out for repair.

Hi: A good thought to check into, but with the unit shown it was tested in multiple chassis and it still did the same errors. Thank you

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.
