  1. Totalizer for 15 mins

    Please help me how develop totalizer for every 15 mins , for real value. Real value should   be taken sample  for 1Sec.
  2. Hi, I am trying to convert a variable of REAL data type to DWORD. I 've tried using Real_To_Dword function which works fine if the real number is integer but when the real is decimal the function rounds the decimal number to INT first (I ve also read it in the instruction manual so no surprise here). I 've also tried experimenting with the function CopyRealToDWORD but again the outcome was not what I expected. Is there another way to convert decimal real numbers to DWORD without losing the decimal portion?
  3. 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)

  6. EA3 Micro Panel

    I want to display the current time of day on mt Micro HMI, EA3-T6CL. Is there a function for this? How can I get the TOD to display?
  7. 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.
  8. 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.
  9. Cpu set clock

    Hi dears, I want to set cpu and NS15 clock with one contact. How can do it in cx programmar and cx designer? Best regards.
  10. 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.
  11. 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

  13. Omron CP1E Clock adjustment

    I'm working on a project with Omron CP1E-N30DR-A Plc (And yes it does have the timeclock) And Omron NB7W-TW00B HMI I'm trying to use the Clock adjustment DATE(735) feature in the Plc program. In conjunction with the HMI to correct the time. Only focused on the Plc program for now. And presume I can accomplish the HMI portion once Plc program is working. Been fumbling with the Instruction manual descriptions several days and seems I'm not getting anywhere. Is there a possibilty to find an example program for this feature somewhere online? Or could someone possibly create an example program? I realize I might have missed some key information things in this topic. But lets see if I get any response at all.
  14. 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

  17. I am new at PLC programming, I have tried some ways to convert a text into DINT and I haven't found the right way yet, maybe somebody can help me. I want to convert "Hello" to DINT, for example. I tried converting it on here  https://www.branah.com/ascii-converter  to decimal and then using it as an input for a ROUND, FLOOR, TRUNC blocks to get a DINT, but when I get the result and use as an input in a DI_R i block the output doesn't match with the first conversion of "Hello". Any tips on how do I get it to work, please? Thanks in advance. 
  18. 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)
  19. I'm very new to sysmac. I am trying to display the current date and time in the corner of each of my HMI pages. I saw a button labeled date and time. It is asking for a variable for behavior. Do I need to write some basic structured text or FB in plc to get date and time and pass it over? I figured the button would update itsself since when I placed it on the screen it had the current date and time and refreshes every time I leave the page and come back. 
  20. real to integer number

    Hello, Could somebody give for me advice how need seperate real number to integer? for example I have in D10 real number 10,9 for me need to do integer number 10 and 9. The real number seperate to integer I am using this LADDER line, attached picture. In D90 I got 10, But how to isolate the number of decimal places,I can not think of. Please help for me
  21. Capture Date and Time

    I would like to capture current date and time to registers in the PLC. I would prefer to use a function block, if possible, since I need to do the capture at different places in the program. I am using a CJ2M. How can I do it?

    Hello. this is my firs post is possible to convert the elapsed time of timer to real or int i need to make some math operation with the elapsed time thanks  
  23. There have been many good discussions on the applicability of cloud-based solutions for manufacturing and process control systems. On one side, some people have concerns regarding security and control of the information, on the other side, there are identified benefits enabled by cloud systems. From VMS minicomputers to DOS and Windows, from ArcNet to Ethernet, it is inevitable the industrial automation systems shall adopt the technologies that are getting predominant in IT general use; the current environment that I am calling the “Cloud-iPad era” is no different; therefore the practical discussion is not if those new technologies will be applied in the industrial environment, but how. This paper is not intended to join the conceptual discussion about the cloud, but just to present a few simple practical examples, where cloud technologies are already enhancing industrial automation solutions and enabling new business opportunities.

  24. Time Input from NB Screen CP1L-E

    Hi guys,     I am trying to make a controller for an oven using MODBUS with a CP1L and an NB screen. My oven program will have 10 stages in one baking cycle, and the parameters for each stage can be modified individually (temperature, blower speed and time). I have set my number input in the NB screen to be a unsigned int of 2 integers and 2 decimals, and it writes to H4 in plc H memory. I move this value from H4 to W4 in the PLC, and input W4 into a timer (T0000). I have tried data manipulation and still have no success in getting this to work properly. My CP1L timer is set to BCD mode, as I am using premade MODBUS function blocks which are programmed with timers in BCD mode. Does anyone have any pointers regarding this? In the screenshot provided, the number i inputed in the HMI was 60.00.
  25. Hello, Completely new to Mitsubishi PLCs and I need to use a date and time stamp for data collection purposes. We have a Siemens PLC as well and this has the data type "Date_And_Time" which is what I need to replicate. I have been attempting to write my own data type but am struggling with how to go about this as it is not straightforward and I cannot find anything about how the Siemens Date_And_Time is made up so I have nothing to go off. Does anyone have an example of a data type they have made that is the same? Or is there a data type which does this already in GX Works 2 that I just can't seem to find?  Please help!
