  2. DATE Instruction for CP PLCs View File Sample code to set the RTC on a CP PLC. Individual sections can be enabled/disabled. Submitter photovoltaic Submitted 03/12/21 Category PLC Sample Code
  3. Hello Sirs! I have a problem with PF527. I get alarms 'control sync alarm' and 'module sync alarm' occasionally. I suppose this meaning that PLC is missing some data from the PF527 device. How to confirm this or what should I do with the problem? Any ideas? Motion group update period is 8ms. Also this device is the last device in the ethernet line. I am thinking to pull the cable directly to the switch near PLC. I am not sure does it help?

  8. 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.
  9. I need a Red Lion HMI to communicate with an IO module (8) IO's ... I don't really need a PLC.  Because the control of a certain LinMot drive for a linear motor can be activated by IO's.  This LinMot drive can store up to 100 curves... which can simply be called into operation by a single binary number between 0 & 255,  defined by eight IO's ..  you input the number on the HMI, the HMI converts to binary and set the (8) IO's in the module which sends the binary number to the LinMot drive..   Yes, there are some other IO's for starting and stopping ... and it may be unrealistic for me to not use a PLC.   I'm trying to get the cost way down...    If a "stand-alone" IO module does not exist... then is there a simple, low budget PLC out there, with 8 or 16 IO's available..?    Thanks much, Michael
  10. 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. 
  11. IC200ALG264 Analog Input module

    Hello all, Thanks for the forum which has provided me with a lot of help overtime. I'm posting my first thread since I can't seem to find an answer to my issue. I'll quickly explain the situation: I'll be installing a RTD sensor to a GE Fanuc IC200ALG264 analog input module using a 4-20mA converter. Everything is fine except I can't seem to understand the polarities of the Fanuc inputs. I'll explain better: the module has an IC200CHS022 for the terminals, 15 terminals total, and the manual is reporting a "number" and a "connection" for each terminal. Now, the "number" seems to correspond to the visible pin of the terminal. But the positive and negative symbols are represented on the "connection", which I can't seem to wrap my head around what it means. Attached are abstracts from the manual and a photo of the terminals. Please tell me where to connect positive and negative outputs of the 4-20mA converter. Thank you.

  12. Hi all! We have a problem with a Mitsubishi system. After switch off the machine in home position and back on, it resets the servo encoder value to 0.  I checked the servo parameters, and the Absolute encoder is enabled, the ext. battery is ok and no zero reseting in the program ( I think...). Is there a parameter I should check or some setting in the intelligent module? The system consists Q01CPU, QD77MS2 im., J4 200B amp with 6v battery, and HG-SR152 motor.
  13. 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)

  17. PID Loop Review

    Hi all, I am trying to set up a PID loop for a project I'm working on, and I was hoping someone could take a look at it for me. Most of what is written comes from the Q, L programming manual, but I've changed a few things so that the program can write changes to the SV as needed. The processor is a Q03UDE and the Analog Module is a Q64AD2DA, using only channels 1 and 5. Thanks for looking! PID Project.gxw
  18. 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.
  19. 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.
  20. 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.
  21. Does anyone know how to reset the "Maximum Total Observed" CIP Connection statistics on a EN2T or a L83 Processor?
  22. 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

  24. 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
