  4. Hi Everyone,   I have  NT31C-ST142-V2 and it has a prompt of "System Program not exist or incorrect." I am trying to transfer via NT Series System Installer but I am getting a time-out error. I have Xm2S-09 serial cable with ATEN serial-to-USB cable.I know it is not broken since I can still Upload/download on a CJ2 PLC. I just want to know what other things I can do upload a systemprogram. I have seen a comment on this site that he remove the battery then tried to upload again.   NT is almost 15 years old. I have a back-up program.   I can't seem to upload by this time for pictures of theH MI and the screenshots of software .
  5. The only thing I can find in help re using the buzzer is to use a multi function button. I want to use the buzzer as an alarm buzzer and turn on $SB13 or $SB14 from a bit in the PLC. Can anyone help please?
  6. CPT instructions on a PLC-5/40

    I'm working to fix/improve the functioning of a program running on an a PLC5/40E.  I think high Scan Times are a big problem with this current program.  ((Backstory:  someone added some quasi motion control, and it sort of worked for a while.  Now that it's broken, the operators of this machine want it back. ))  I'll keep my question simple, PLC5's are new to me: There are 36 rungs with CPT instructions as the sole output, a third of these instruction are executed every scan.  I'm going to replace them with MOV instructions. My question is, is there any sneaky PLC5 reason to do a CPT instead of a MOV?  Is there a better way to do this? The CPT instructions that execute move integer values to a data file used by the HMI to control the coloration of touchscreen buttons.   Thank you for your time. PS: I'm new-ish to this forum, please feel free to let me know if my question was asked correctly or not.
  7. The CC-Link system on a machine has been intermittently dropping out.  Normally the Link Scan Time runs at a solid 87ms.  When the system "drops out", the link scan time will increase.  Sometimes double, triple, or go up 10x. It happens when the machine is running or when it sits idle. There are 33 stations on the network.  The same stations do not always fault but sometimes all of the stations will fault at once (as seen in the attachment pictures.) We have changed the main QJ61BT11N, the processor, the Q62N power supply, the main backplane (base unit), all cards on the main backplane.  Is it possible for one station or one of the cables to create a network wide problem?  Any ideas thrown at us would be appreciated. 
  8. friends, forgive me for my english.  I have a problem.  omron nt620c panel cannot access the system menu.  I reinstalled the system program through NT-SYSTEM INSTALLER.  after which I get the message: no direct information is set !!!  please use the support tool to set the pt control area and the pt notify area.  go to the system menu does not work.  I swing the corners of the screen as described in the manual.  from a video from YouTube I realized that there should be a message connecting to host
  9. I am trying to display the time from an Accumulation timer. Using a data display object I am able to see the time in the following format 00:00:00.0000000. Is there a way to format the time without the decimal seconds I just want to see 00:00:00 (hours:minutes:seconds)

  13. So I have done quite a bit of googling and i even reached out to our integrator but i am having a nuisance fault of "Watchdog Fault" Caused by periodic task overlap. The task is scheduled to start again before it is finished. I added all of the Programs in this task MAX scan time and it only came out to 102 ms. the task is scheduled for every 100 ms. The watchdog is set at 500 ms. The task is currently running at 146-148 ms and i confirmed this using a TON instruction at the end of the task followed by a reset. What can i do to get this down?? What would be the best practice? Move programs into another task? Make the task continuous? What would happen if i did make it continuous? I tried setting the task to 150 ms and the controller DID NOT like that. I was barely able to get back on line with it to change it back to 100 ms. CPU usage is at 91% and this task accounts for around 50% of that. Thank you all in advance for your help.

  17. Tracking the master clock

    We are having issue on a machine running kinnetix 5500 drives where we randomly get clock Sync Faults.  This particular machine is set up as a slave looking to another PLC(L36-ERM) on a different station of the same machine as the time master.  There are about a dozen other PLC's(totally different machines) on the same network and most are set up as masters for their own systems and to my knowledge they have never had this issue. There are also dozens of other devices connected to this network, and then this network is part of the facility wide network.( I apologize if this is a little wordy) We are pretty sure that the slave is finding a more accurate clock on the network somewhere and syncing to it causing the servos to fault. We have tried making both the master, and the local clock of these 2 particular PLC's higher priority than the others to eliminate this with no success. What I am trying to do is track what clock this particular slave is looking at as its master when the clock sync fault has occurred.  is there away to do this through ladder logic?  it seems like we should be able to get this information and save it so we can figure out who the culprit is.
  18. Still learning Sysmac Studio......how do I gain access to System Variables like 'PageIndex" so my PLC can be notified what Page the HMI is on?  Also, how can I execute an 'Acknowledge All' from the PLC so I can reset the 'Alarm Viewer Popup' from my PLC? Thanks,
  19. Hello Everyone, I am new at this forum, seeking help from you guys and gals. Scenario: I have a Controllogix 1756-L71 5570 controller installed with 1756-TIME module. The function of time module is to take time from GPS clock module in NTP format and send it to controller in PTP format. All the status LED's on Time module are OK. Also sync LED is Green. Still the time of controller is not synchronized with GPS clock there is a difference of 45 mins. Fellows please help. I'll be helpful.
  20. Hi everybody,For a while I’ve been wondering, in every plc forum where the use of loops come to discussion I find most people answering that it’s best to stay away from them and that there are better, easier and mostly less scan time demanding solutions out there. Why is that?In my experience they’re the next best thing.Why would referencing data from an array of 40 Dwords using a FOR X:= 0 TO 40 DO loop be any more scan time demanding then the PLC scanning through 40 rungs of statments?Just curious if I’m missing something here. Cheers

  22. PLC Not fast enough?

    Hello, I used a Schneider Electric SR3B261B PLC to create a trivia machine (as I call it).  Basically 20 buttons that let contestants ring in to trivia.  There is a display that shows the number of the person who rang in.  It works pretty well unless people press the buttons at exactly the same time.  Then it shows 2 results at the same time.  Usually resulting in a display of 18 when really it was 12 and 14 that rang in, for example. The PLC has options for: "Adjustment of the basic cycle time of the module."   and "Type of Hardware Input Filtering." Which I assume would make the PLC operate faster and avoid two inputs triggering at the same time.  If I change the setting and update the changes do not keep.  I appear unable to change it past 20 x2 ms  and slow (3ms). Is that a correct assumption that changing this would fix it? Why can I not change this?  Is it because I have so many inputs (14 or so) and Outputs (16 or so)? or because my program uses nearly all 240 lines of ladder logic allowed? What can I do to fix this?   Emerald
  23. Hi all,  I am trying to update the firmware of a NS12-TS01B-V2. I have downloaded the RecoverUpdate_8_95.exe (and someothers) from the myomron website. I have followed the instrucctions PDF, but when I switch on the HMI with the Compact Flash inserted, nothing happens: the screen is dark and the led is lit orange (not blinking).  The compact flash is 1GB (not omron) and formated using a CJ2. I have been using this card in OMRON PLCs and HMIs for years without problems.  I read in other topic than I guy had similar problems and he solved it using other computer and other unzipper program. I have tried it, but it did not work.  After that, I tried to update it using the DIP switches, but I got more problems, because I got a Warning first, and later an Error, because I forced the installation of the Firmware of the NS8 (BANK1) instead of the NS12. However, the other BANK folder contains the FW for the NS5... Anyway, I could fix this error because previously I did a backup of the already installed system (V7.0). I would like to ask you to send me a BackUp of another NS12, using the "Manual Transfer", that should works. I need the 8.20 version or higher.  Thanks a lot.  My email is hector.moreno.lax@gmail.com
  24. Do-More Designer

    Trying to program production tracking in Do-More 2.3. Need to track current Date, Time of day & current hour.  Anyone have an example of how time of day is used? I have done this in Allen Bradley 5000, but this Automation Direct stuff is new to me.
  25. Hi,   I'm pretty new to allen Bradley and wanted to know if there was a function that could help me out. I have a rotation sensor which feeds back to the PLC via a digital input, once every half second or second once machine is up to speed - I want to record the off time of this DI (how long it is off between pulses, essentially how long it takes for drum to rotate once). Is there some way to record this time and use this value for compare logic? any help would be greatly appreciated.   PLC: Micrologix 1400 series B RSLogix 500 version 11.00.00 (CPR 9)
