  2. Followup:   now on a bigger screen, I see the "Path to Module" in the ControlFlash log as "1 16 0 1".     That suggests that the Path given to the ControlFlash session was recursive and pointed through the backplane, then back to the controller.   I don't have a controller handy to check on this, but it makes sense.
  3. Ok, now i get pretty confused :( FX3U-232ADP-MB FX3U-485ADP-MB FX3U-485ADP-MBH Are these just specialized MB cards, or are they able to do more then ENET-502, when it comes to modbus? EDIT: I'm overmanualed from last few days, even now i've few open, so thanks to anyone who will answer this, even if it is proly just one manual away from me.
  4. Thanks for reply I would like to try FX5  too, but we have some FX3GE in spare parts, and this is not number one priority project, so budget is limited.
  5. Post a screenshot of that RSWho window. When you browse RSWho, be sure to select the FIRST controller object you see in the communications tree. While you can "drill down" from the Ethernet interface to the backplane to the CPU object, that's not the appropriate path for one of the modern CompactLogix controllers where the Ethernet and the CPU are integrated.    
  6. Current Mitsubishi PLC are from Mitsubishi Electric. These seems to be from MHI Mitsubishi Heavy Industries
  7. fixed scan execution

    You  probably haven't programmed an EI (enable interrupt) in your normal execution program. Fixed scan needs interrupt to be enabled

  9. communication pc to plc

    What is your question ? What do you need to know?
  10. Thanks for the quick reply but the plc is not in run mode and i tried the little reset button but still have the error  
  11. Open The Door and switch the switch to Remote [REM]. PLC is most likely in run.
  12. I have a new plc and am trying to connect the first time on power up.  I have done this many times before but now am having an issue that I do not understand.  When attempting to connect the first time I am using my usb connection in RSwho active and selecting the processor.  When attempting to upgrade the firmware I am getting an error stating" Failed to begin update to the target device.  The target device is not in the proper mode to accept an update." its error message 11006  .  I have the switch to program mode, I reset the power a couple times and still no success.  I cannot clear a flashing red light on the plc ok status light but i think its because there is no program in the plc yet.  what am I missing??  i added the pics of the error messages.     
  13. S7 300 Profibus fault

      Below is the fault detail of diagnostic buffer   Event 9 of 211:  Event ID 16# 39C4 Distributed I/Os: station Failure Address of the affected DP slave: station number:   17 DP master system ID:      2 Log. base address of the DP slave: Input address:  8170 Log. base address of the DP master:   8191 Requested OB: Rack failure OB (OB86) Priority class: 26 External error, Incoming event 08:16:49.888 AM  12/10/2017   Regards, Danish Abbasi
  14. S7 300 Profibus fault

    Dear Jairus, We have the software. We have checked Diagnostic Buffer 100 times.One node node goes off for just a moment, hardly for a milli second & then comes back, checked through Diagnostic Buffer. This happens sometimes in a hour, sometimes in 6-7 hours. We have replaced all modules of that particular node but the problem is persistent. I will upload the diagnostic buffer in a while.
  15. from the software of your HMI try to search if the s7-300 plc is available. i mean try to check the compatibility first. what model of delta HMI you have and the model of s7-300?  we can use profibus or MPI protocol or even profinet.  
  16. S7 300 Profibus fault

    You need seimens step 7 software and  try to troubleshoot online.  go to the diagnostic buffer, and it will display which module or any that causing the problem. or go to the hardware configuration and online, you can see from there the modules condition, the module failed to communicate will be mark with x. is your CPU SF led is ON? what is the condition of the CPU? any red led is on. i mean the BF? SF?. try to secure the software, it will not take time troubleshooting if you have the software. 
  17. S7 300 Profibus fault

    Dear All, We are in need of your expert opinion. One of the nodes of our Crane's Cabin gives a station failure problem, due to which whole Crane shuts down. we have done everything from replacing Dp connectors to changing Profi cables, swapping modules with other stations, changing Power supplies but the problem remains the same. Following are the system details, 1. CPU S7 319 F3 fail safe 2. IM 153 interface module 3. OLM module for signal conversion fibre to profibus from main CPU.   We have several nodes after OLM but fault was persistent with 3 nodes. After comprehensive working, it came down to just one but still not diagnosed. I will also upload the diagnostic buffer if needed.
  18. RSLogix 5000

    After install finish can't open PLC have alarm fatal Error, how to fix it?
  19. Is it common for vendors to list the wrong specs for products? I bought a 1746 IV16 on eBay dirt cheap because it was listed as being a digital sourcing input module. When I go to Rockwellautomation.com , it agrees with this. I've only checked two other vendors, and they both have contrary info listed. PLCProducts.com says it receives analog via current or voltage, and qualitrol.com says it's a digital sinking module. Oh, and the text I'm teaching this from by Rehg and Sartori have it listed in a table of "discrete i/o modules" and call it a sinking module. Im assuming that qualitrol, eBay, Rockwell, and the text have it right that it receives digital and not analog inputs. But the text and qualitrol may be wrong in their labeling it a sinking one and not a sourcing one as Rockwell and eBay (not usually my most trusted source) have it listed.  In the end, it was $8 and I don't care if it isn't what I thought it was, but in your experience, do you find such wild inconsistencies in specs? Thanks!
  20. Last week
  21. Yes Enet-502 provide modbus tcp, you can find libreary in mymitsubishi portal, but better spend money for Fx5u.

    Thanks a lot... was really unaware of CutePDF... Thanks once again
  23. PID

    Good afternoon, I have been suffering for a long time with this PID. At first I tried to use SimplePidFX, but I do not how to run it. No, I could run it, but it does not work exactly as I need it. I do not need an auto pid. I picked up the right settings on the manual on the metacone and now I wanted to remake the old program with a new one. Then I found this example of yours, but it does not work for me. Help me please. http://plcforum.uz.ua/viewtopic.php?f=3&t=25693&p=81981#p81981
  24. could you tell me how to create internal tags in DIAview and how to dynamically change the colour of any object taken in SCADA

  26. Actuator Sensor Interface

    I did look at Her Majesty's Ship AnyBus. Three hundred combos, amazing. So, hypothetically, I can do AS-i for fun and party tricks, with merely this: Automation Direct BRX PLC supporting Ethernet/IP, Modbus & friends Network switch / crossover cable / etc HMS Anybus AS-i to say, Ethernet/IP All too easy? I did call/email A-D's tech support but I think I confused them. PS: I like Ethernet/IP. Saying "Ethernet/IP" is like saying "Highway/Sedan".
  27. Ladder program save in PDF file

    Simple way is install CutePDF.  It makes a printer that writes to PDF.   Then just open your programming software and print your project.
