  1. Can a CJ2M communicate to a C200H??

    Hello! I just got an interesting request from a customer, we have a product line that uses C200H PLCs.  The cabinets can operate independently or they can be connected to work in a Master/Slave configuration, the C200 PLCs communicate to each other over RS-232 using LR registers. Back in 2015 we redesigned to use CJ2M PLCs and changed the communication to EthernetIP. Now we have a customer who wants to buy a new slave for an old C200H system, so my question is what are my options for communicating to a C200 with a CJ PLC, I don't have much experience with the C200, that was programmed before my time here, in 2000 I think. Thank you!!!      
  2. Can a CJ2M communicate to a C200H??

    Our CPU is the C200HG-CPU43, back when it talked to another C200 we used the Comms Board A and the 1-to-1 PC Link with the LR registers. When the C200 went obsolete we upgraded the controls to the CJ2M-CPU33 and began utilizing the Ethernet IP communications...so our new system doesn't even have a serial port at this time, we would have to add the CP module to the option slot.  
  3. Looking for L_CPU Identity.Status bit documentation

    Just wanted to follow up on this in case anyone is trying to figure this out in the future.  I finally found out that these bits can not be accessed except for by the associated face plate/GUI object that goes with this AOI for an AB SCADA or HMI, so they (Allen Bradley) will not tell me the meaning of the individual bits. My application is using a GE iFix SCADA so I will not be able to use these bits to send status.
  4. Hello! I am using the Plant PAX AOI L_CPU_24_Up and am having zero luck finding out both independently and from tech support what the 16 bits of the Ref_Out.Identity.Status are. The description says Tag to receive CPU data, device status (bitmapped, see documentation).  I have a techconnect contract, but cant find the correct documentation where this information lives.  Could someone please send me a link or just give me the number of the publication.  I attached a screen shot of tag info I am looking for. Thank you!!!!    
  5. Hi Chris, I was just looking in the AB forum and saw a bunch of posts that don't look like they belong there (and all from the same user)...they are pretty new, in the last 15 minutes, just wanted to let someone know right away!

     

    Thank you!!

     

  6. So I ended up using the NJ CPU with an Omron DeviceNet card, Beckhoff was not sure that the Omron EtherCAT Master would communicate with the DeviceNet Master card on the Beckhoff EtherCAT coupler, they were certain that we would have no issues communicating with the Beckhoff EtherCAT coupler, but the issue was then communicating to the DeviceNet Master since that was designed to work with their PLCs, since I already have the Beckhoff components laying around I am hoping to try it some time, but I just didn't have time on this project and had to go with what I knew for certain would work! Thank you for your input and if I ever get time to try it out I will let you know the outcome!
  7. Hello! I am working on a quote for a new project that will use EtherCAT but also requires DeviceNet for some legacy components.  Has anyone successfully used the Beckhoff EtherCAT coupler (EK1100) with the DeviceNet Master Terminal (EL6752) and an Omron PLC as the EtherCAT master? My concern is that the coupler will only communicate with the Beckhoff EtherCAT master, but since it is so much more expensive to get the new Omron parts to communicate DeviceNET i am hoping this could be an option.  The equipment is extremely simple and price is a major consideration.   Thank you!!!
  8. Thank you, I am so used to using the manuals for CX-One instead of the help files I never thought to check them!!
  9. I am trying to use the Event "SaveUserAlarmLogToFile" tied to my F1 button to save my alarm history to my SD card installed in my screen, but I can not find any details on how to specify the file name for the save...can someone please clarify what should be entered for the file name?     Thank you!!!!
  10. NA5 Orientation

    I was wondering if the NA5 could be flipped for a portrait orientation, I am working on a new project that has serious width restrictions!  I looked through the Sysmac software but could not see anywhere that it could be done in the hardware configuration.   Thank you!!
  11. I am a long time Omron user, but this is my first time using the Sysmac software, I want to compare the 16 bits of my array to zero, if any of the bits are on I want to turn on an output, I see the AryCmpNE and AryCmpNEV, but they have a seperate bit for each item in the Array, is there any way to do this without using Unions?   Thank you!!
  12. I am beginning my first project with the newer NX platform and am a little confused by the description in the manual vs what is actually in the sysmac setup.  The manual makes it sound like you can adjust the range settings for the card, but I don't see any where to do it in the setup.  I also don't know what the Index and sub-index columns mean, so I am wondering if this is a back door to access the range settings? 
  13. Hello! Just wondering if any one has any experience with the Velocio PLCs, they look like a perfect fit for an application I am developing where we need something extremely small; but I am reluctant to specify them into a product line because I don't really know much about them or the company. I am hoping someone here has had some good experience with them they can share as a testimonial!  Any info about the PLCs reliability would be greatly appreciated.   Thank you!!!
  14. Subtracing Date and Time

    Thank you Jay!  I just had to do the same thing for one of my projects so happy to share!!
  15. Subtracing Date and Time

    If you can use Structured text this should work: (*I USED THE SAME TIME STAMP VARIABLES IN THE EQUATIONS BELOW WHICH ARE JUST THE PLC CLOCK ADDRESS IN MY PROGRAM, BUT THE 1 AND 2 LINES SHOULD BE YOUR TWO DIFFERENT TIME STAMP VARIABLE SETS, YOU COULD ALSO INCLUDE THE MONTH AND YEAR IN THE SAME MANNER IF NEEDED*) UINT_DAY1:=STRING_TO_UINT(LEFT((WORD_TO_STRING(CLOCK_DD_HH)),2)); UINT_DAY2:= STRING_TO_UINT(LEFT((WORD_TO_STRING(CLOCK_DD_HH)),2)); (*SUBTRACT THE TWO VALUES FOR YOUR DAYS REMAINING RESULT*) UINT_HH1:= STRING_TO_UINT(RIGHT((WORD_TO_STRING(CLOCK_DD_HH)),2)); UINT_HH2:= STRING_TO_UINT(RIGHT((WORD_TO_STRING(CLOCK_DD_HH)),2)); (*SUBTRACT THE TWO VALUES FOR YOUR HOURS REMAINING RESULT*) UINT_MM1:=STRING_TO_UINT(LEFT((WORD_TO_STRING(CLOCK_MM_SS)),2)); UINT_MM2:= STRING_TO_UINT(LEFT((WORD_TO_STRING(CLOCK_MM_SS)),2)); (*SUBTRACT THE TWO VALUES FOR YOUR MINUTES REMAINING RESULT*) UINT_SS1:= STRING_TO_UINT(RIGHT((WORD_TO_STRING(CLOCK_MM_SS)),2)); UINT_SS2:= STRING_TO_UINT(RIGHT((WORD_TO_STRING(CLOCK_MM_SS)),2)); (*SUBTRACT THE TWO VALUES FOR YOUR SECONDS REMAINING RESULT*) I am not sure it is the best or cleanest way to do it, but it will work!
  16. I recently had an issue where a system shipped to a customer's site with a mismatch between the IP address loaded into the CJ1W-ETN21 card and the node dials on the card itself.  We had been testing the settings of the card by pinging the address and had assumed if the node dials were wrong we would not be able to ping the card.  As we just found out that is not the case! Both our quality department and our customer's end user were able to ping the Ethernet card, but the end user could not establish FINS communications because the node dials were not correctly set. Is there a way to test that the dials are correctly set?    Thank you!!!
  17. I am trying to use FINS/UDP network to communicate with a Siemens device (at a customers site over seas from my home office), today I attempted to set up a SEND command based on information my customer received from a local Omron representative but had no luck.  I feel like I am missing something in a setting somewhere, does anyone have experience doing this?  I am using a CJ2M-CPU35's built in Ethernet IP port which is also communicating to 5 other Omron devices over Ethernet IP, so I am wondering if there is an issue having both networks. Thank you!
  18. FINS/UDP Help to a Siemens System

  19. FINS/UDP Help to a Siemens System

    I think that will be okay for me at least if they don't respond, I don't know if it will cause issues with the command...our equipment is communicating to their Central Monitoring system which is the Siemens so all I need to do is send them our system status and some analog readings...its 320 words worth, but still just need to send/output from the Omron PLC to them.  I was able to get the information that they were given here in Europe...the two PDF files are directly from Omron and the word file is from another vendor who successfully implemented the communications. I will try to upload them in another post...  
  20. FINS/UDP Help to a Siemens System

    My customer had a "how-to" email from Omron here in Germany detailing what to do...I just could not understand all of it because it was in German, (I am trying to get a copy of this so I can share it with you).  On my end (the Omron CJ2M-CPU35) it just had some setup for a SEND command and then the execution of the command and some error checking.  I programmed it in the way they showed it on the sheet but I think some of the settings they had may not have matched my configuration...I was also worried it would interfere with my Ethernet IP network.  
  21. I have an existing project that I have used the smart active parts for (and they worked great), I copied this existing project to create a new one but the communications changed from Serial to Ethernet IP...so I used the replace host feature to convert the serial comms to Ethernet IP, now I am not able to get the SAPs working, I edited all of the destination network and node addresses but only the CPU Unit Status display cycle time and clock information appear to be working.  Do they not work correctly over Ethernet IP or am I missing something?  I was not able to find very much on setting up Ethernet communications with the smart active parts so I don't want to spend a lot of time on it if it is not possible...   Thank you!!
  22. I READ IN THE MANUAL FOR THE CJ2M-CPU34 THAT IT IS POSSIBLE TO CHANGE THE IP ADDRESS BY WRITING TO D30098 AND D30099 (MY DEVICE IS UNIT 0).  I TRIED TO DO THIS ON A TEST PLC BUT AM NOT HAVING ANY LUCK... I WROTE MY IP ADDRESS #C0A8 TO D30098 AND #0E30 TO D30099 (IP ADDRESS 192.168.14.48) WITH THE CPU IN PROGRAM MODE, I SET THE RESET BIT (A501.00) TO TURN ON ON THE TRAILING EDGE OF THE FIRST SCAN BIT, I CAN TELL THE CARD RESETS BECAUSE I AM CONNECTED VIA ETHERNET AND I GET DISCONNECTED, BUT THE IP ADDRESS DOES NOT CHANGE.  IS THERE ANY WAY TO CHANGE THE IP ADDRESS WITHOUT CX-PROGRAMMER?  I NEED TO GET A SOLUTION TO MY CUSTOMER TONIGHT AND MY SUPERVISORS DO NOT WANT TO RELEASE OUR DEVELOPMENT CODE TO THE END USER.   THANK YOU!!!
  23. CHANGING IP ADDRESS IN THE LADDER?

    They do not have the CX-One or CX-Programmer software, is there a separate utility just for the IO table that we can provide them?  I am in NY and they are in CA...
  24. PCS7 with S7-410 for Dummies

    Thank you!!
  25. PCS7 with S7-410 for Dummies

    I just need to understand a little bit more about the PCS7 architecture, if someone could point me to a document or a video or something, or just give me a few sentences to break it down it would be greatly appreciated. The reason being, we have a quote that we are working on for a customer over seas and are being told to quote our equipment with an S7-410 PLC.  I am very unfamiliar with Siemens in general, but completely unfamiliar with the PCS7. Our equipment is typically if not almost always stand alone equipment that communicates discretely to the rest of the facility.  Our equipment is not part of a process line, but rather feeds the process line equipment what it needs to perform its operation. I have been led to believe that the S7-410 PLC must be part of a DCS, so it does not seem like the correct fit for our equipment.  I just want to confirm this and learn a little bit more so I can explain to our sales folks and ultimately the end user why it is the wrong option for us and our type of equipment.   Thank you!!!
