  1. Hello Everyone, I am writing one logic and need some help regarding that logic.   CURRENT LOGIC -  -There are two timers TON_1 and TON_2. -TON_1 timer will start as soon as PLC turns on. -After the done bit of TON_1 timer, the TON_2 timer goes on. -After the done bit of TON_2 timer, again the TON_1 timer will start. -This logic cycle will run continuously, both timers will run turn by turn. Code (Codesys/Schneider Eco Structure Machine Expert)- PROGRAM POU_1 VAR      TON_1: TON;     TON_2: TON; END_VAR TON_1(IN:=(NOT(TON_2.Q)) , PT:= T#100S); TON_2(IN:=(TON_1.Q) AND (NOT(TON_2.Q)) , PT:= T#20S);   Actual Requirement -  -There is a BOOL tag. -If the BOOL tag gets high during the TON_1 running, the logic should move to the TON_2 immediately. -If the BOOL tag does not get high during the TON_1 running, the logic should move to the TON_2 after completion of TON_1. -after the completion of TON_2, again restart TON_1. -Logic Runs continuously in a cyclic mode.   Give me your valuable idea to fulfill the logic requirement.

  4. Unconverted Ladder Code?

    berkotropia posted a topic in Mitsubishi

    Hi All, Please see attached screenshot: Whenever I want to save the ladder program or start simulation, this window pops-up. If I press 'yes' I loose the whole work. I tried to open existing program and modify it, but it did the same. When I clicked 'yes' I lost all modification and just the original program remained. (I made the program in the morning, opened and saved many times but it started popping this window later.) I work with FXCPU series, FX3U/FX3UC type, simple project in ladder. This worked well but now is not anymore. I use Melsoft GX Simulator! Can anyone advise why this is happening? It is very annoying! It is pointless to work on anything now! Many thanks
  5. Hello, On our DCS we have a button that will open an RDP connection to our PLC server and open the .mer file connecting the DCS to the PanelView HMI. This is supposed to be used for troubleshooting purposes only, but that is not the case. Is there a way to prevent operators from operating the HMI through the RDP while still allowing them to have read only access?   Thanks, Michael
  6. So we have a PLC project coming up and its our first one and understand and can execute most of the sequence without issue.  The part that is getting me is how to handle the following efficiently using studio 5000 and panel view.   AHU has to be able to run test cycles User selectable up to 250 steps in a test cycle User selectable temperature setpoint for each step User selectable humidity setpoint for each step User selectable time duration for each step   I thought about using arrays but as i understand the allen-bradley plcs to change the array size you have to go offline and then back online so you could not change it dynamically.  Was considering doind this with reading the dataset from an excel document the user would edit. The other option for me is to have a static arrays size and then based on the number of steps the user select have the routine only execute x ammount of steps, which is done easy enough.  Big thing is after the code portion is lined out is there a way to dynamically change the hmi graphics to only display certain steps for the user to edit, maybe by using an array of bits that are on and off for visibility and then having a GUI object be shown or hidden based on that bit?

  7. Crane Positioning

    Nico1976DK posted a topic in NJ Series / Sysmac Studio

    Hey folksI'm trying to make a Ladder program in Sysmac Studio to control a Crane.The crane gets via a HMI a position that it must drive to, first at high speed then in low speed this is controlled via encoder signal for fine positioning there are several sensors.For all this I have an NX1P2-9B24DT1, NX-EC0222 and 3G3MX2-A4030-ESomeone here who can help me with an example of how this can be done in Ladder.Many thanks in advance for your help.
  8. Hello everyone, I am new to PLC programming and will start working on Allen Bradley PLC. I have an experience in computer programming languages. Will learning ladder logic be a better option or starting with structured text as i have some knowledge about the syntax and programming of structured text?
  9. So, I have thought about creating my own Business for the last few years. With this business I would go shop to shop/factory to factory teaching anywhere from Basic PLC programming to HMI design and integrations. I love to share any bit of my Knowledge/experience with anyone and I have learned this more when at my first engineering job they had me train several guys on how to start up Servo Motor jobs with PLC and HMI's. I really enjoyed helping others learn and get over the hump of intimidation and lack of experience with electronics and such. I have had a lot of different experience from being an Electrician for 5 years to Engineering 10+ years now- (Design, Software, Startups, Service work, Installs, and Management) I then started a career of being a PLC Instructor (part-time for 1 year now) for adults and this too help me with my idea of starting my business. At my instructing school we would get a variety of people anywhere from fresh out of High School to experienced Maintenance guys that want to specialize in PLC and HMI's.  With all of this being said, does anyone think there would be a great amount of need for someone to come your work place and teach Allen Bradley, Omron, and Mitsubishi PLC and HMI and maybe one day down the road Servo Motors and logic for them too? I think that more one on one with a couple trainer lab stations, I could really help not only workers advance themselves but also companies benefit both? I have gone to training for my previous employers, sometimes traveling far away for a week at a time and costing my employer a lot of money where my rate would be much less and on-site of the customer/trainee's. Starting out I have bought several used pieces of PLC's, Input Cards, Output Cards, (Only Allen Bradley for now). I have also bought cases to make my training units more safe and portable. Looking at creating a business name and logo as well as possibly creating a (LLC). It has been a slow but steady process though. Feel free to add anything or comment anything to this with ideas.   Thanks!

  12. communication

    akashleo posted a topic in General Topics - The Lounge

    i want to communicate ml1400/compact logix L24ER to simatic s7200 via ethernet.Please help me with it i am new to it and dont know how to do it.
  13. HiI have just bought a new AB CompactLogix 5380 (5069-L306ER) labeled "FACTORY SEAL".When I trying to connect via USB or Ethernet on studio 5000 softwares, no matter RSlinks or BOOT-DHCP tool, there is no responding at all.I know these PLC shipped row and there must be flash before using for first time, But I think when I turned it on via MOD Power, while connected to PC, there must be some sound for connecting via USB cable, or some activity in small led's of Ethernet port in both sides. but there is no response at all.I'm begining to doubt about my cables, although the USB cable and the Ethernet cable are standard cables, I try it with two or three cables.P.S: The package does not included a SD card, I put a SD card from my own, Could it be problematic?Thanks.
  14. Hello!   I have a humidity sensor 0-10v and his measurepoints is for 10 to 90 humidity %. Using the Analog Amplifier, I set his measure range but theres a problem... he's only givin me integers numbers, and I need the decimal one's to. On the Analog Amplifier, with that range the program says that the gain on the measure is 0.08 for each number on the analog input, theres a way to see that decimal places? I tried increasing the measure range to 100-900 and set the decimal case to 1 but the gain turns to 0.8, with that I just can take jump number like 10.8->11.6->12.4. How can i do this on the way that I need? It's an LOGO 8! After setting measurement range from 100 to 900:
  15. So I have a plc program where most of the outputs are based on a counter that goes from 0 to 1000. The counter speed is adjustable and is generally set to run through a full cycle (count from 0 to 1000) anywhere between 0.5 to 2 seconds. The problem is, when I try to energize an output by using an EQU instruction, it will almost always skip the count because the scan time is not fast enough. I've been using a LIM instruction which has been working, but its not quite as accurate as it needs to be. I switched the counter logic to be continuous to try to make it faster which made it almost perfectly accurate... But only in the continuous task; it made the other periodic task significantly less accurate. I was curious if any of you had any tips on how to remedy this or just general help. I am still relatively new to PLCs and ladder logic so any advice would be awesome, Thanks in advance! Edit: The purpose of the counter is to cycle through from 0 to 1000 over and over again. My outputs actuate during a certain interval within this cycle (For example I would say actuate from 300 to 800 and it would stop and end once it hit those values via an EQU or LIM instruction). I wrote the logic as follows: First I calculate how many cycles per minute I want to perform, using that value I calculate how many times I want to increment my counter per millisecond. Then a timer is given a preset of the total cycle time. While that timer is running I continuously multiply the timer's accumulated value by the "cycle count per millisecond" that I calculated earlier; the resulting value is the current count that all my outputs are based on... Hopefully that makes sense, I know it's not the best but I could not figure out a better way of doing it and I know rounding is certainly making the accuracy worse. My hardware is: Allen Bradely PLC (5069 l306erms2), 5069-ob16, 5069-ib16, and a Kinetix 5500s2 Driver for my motor(s)
  16. Hi there, I am fairly new to programming serial communications, especially with Mitsubishi PLCs. Can someone walk me through in ladder logic how to bring in ASCII to the PLC, store the data in the data registers. Then send the data out to another PC once an 'X' input is satisfied? ASCII code would go like the following: C2,0,1,123,2,ABC,3,456,CR

    Hi, I'm trying to open files with rsp format which i believe is for PLC5. Is there anybody who can help to print the file to pdf? WV.rsp
  18. Hello everyone 👋👋👋 I saw "No Project" displayed on the PLC, and I don't know what it's mean. The machine have one PLC and some of the digital I/O stopped. I think the plc lost the program, Am I correct? Also when I connected with laptop and RSlinx software I found only the plc module is working and the other modules are off. I hope get answers from you soon. Thanks in advance.
  19. Hello guys. I have problem create communication between Omron FQ2 camera and Allen Bradley PLC. Can anyone advise me ?  I set it up according to this manual: ftp://85.129.89.106/Vision/FQ/Communication/EthernetIP/FQ2%20to%20AB.pdf.      
  20. Hi guys, I'm new in the forum and I'm quite new also in Sysmac programming, in ladder programming at all, to be honest.   I have some years of experience in programming CNC machines using C, on a owner platform. most of the functions I was using there were developed using "step sequences order". I mean, I had functions continuosly running where I was able to control the steps,  using the switch/case contstruct, and pass to a step to another just changing the reference variable. To be more clear, something like this:   functionStep = 0; switch (functionStep)   case 0:        if !(somethingToDoHereIsDone())                      break;       functionStep = 10;   case 10: .... and so on.   In the Sysmac programs I was able to see, something like this is possible to perform using register and AryShiftReg function. but I find it's quite complicated to manage if I want to insert intermediate steps in a second moment and most of all let an external part of the program to know in which "logical step" I am in my function.   Can you suggest me, in your experience, how can a sequencial function can be defined in Sysmac?   thanks a lot for your help.            
  21. Hi all, I'm having an issue with one of the Kinetix6000 allen bradley servo drives on a filling line that I support. This particular servo motors controls the rotary movements of a series of pumps to ensure accurate dose timing. Every time that I start up the machine, the PLC (Controllogix L7 firmware v28) executes a homing sequence to ensure the servo finds its 0 point. However, the servo in question keeps getting an 'Overspeed Fault' (E55). So far in troubleshooting, we've basically changed every component. We replaced the drive, feedback cable to the drive, and even hooked up a new free-spinning motor directly to the drive. Every component change has resulted in the same Overspeed error shortly after the homing sequence starts. To try and rule out a mechanical issue, I even disabled the homing sequence in the PLC and tried to move the motor using Motion Direct Commands. Immediately after a MSO command, the drive faults out for OverSpeed even with no motion. The last bit of troubleshooting we swapped the position of two of the drives, but the same OverSpeed fault happened on the drive connected to the rotary movement motor. At this point, I'm even considering changing the sercos fibers and the Kinetix power rack. Has anyone experienced anything like this before, or have advice on what to try to make it work? Thanks in advance for all your help  
  22. Hello! I have a plc program where I need to start and finish an MAM instruction based on a set amount of time. I am trying to calculate the speed of the motor based on the time but when I do, its always off by some milliseconds which I cannot have. I thought this was due to not considering acceleration time but changing acceleration does not change how long it takes the instruction to complete. Is there a more reliable way to perform this? Currently I have my speed units set to seconds which I thought would work (and did improve it slightly) but there is still a slight offset in time. If there is no reliable way to do this, is there a reliable way to predict what the offset in time may be? or what is even causing the offset? thank you in advance. Edit: Or should using seconds work fine, and its more likely something else in my program?
  23. Hello guys, I'm a new guy with Panel View 800 and I have few questions from beginning. I have an application 2x PV800 4" and 1x CompactLogix L24ER.This application require recipe management and I've found that PV800 has weird-different representation of recipe management. I can't figure out how to add additional recipe to the recipe list. Usually I can add new blank recipe without any extra steps, but it's not "add recipe" buttons. I'm looking an answer for next questions: - how to add new blank recipe my template that I made ( picture - https://drive.google.com/file/d/1jcQvbBL0MfSuwHxMsV3ZVz1oPiTY0u3G/view?usp=sharing) - how to get currently loaded recipe name? I have assigned status tag, but it always shows me a number. I didn't find any sort of system tags with selected recipe. - I have installed CCW software v.12. It allows me to create a project with PV800 FW 5.011, but I got a panel with default FW 5.013. How can I add new firmware version into my CCW software? I found AB video about PV800 and recipe (https://www.youtube.com/watch?v=ewgBh4ldXXU) but it useless without an example file.   Thank you in advance! Regards, Scotty
