  1. Hi All, On our plant, we are using one Rockwell  PLC model 5573 with HMI(Allen Bradley 1500P). I am automation engineer but I did not work on the Rockwell PLC. Now I am planning to install the GPS clock on our plant. And I want clock will synchronize our Rockwell plc as well. Could someone advice what is the best option for this model to do the time synchronization.   Thanks in Advance, Warm Regards/Waqar

  2. Time of Day in NA

    Haakon posted a topic in NJ Series / Sysmac Studio

    Hi.  I am quite new to Sysmac Studio. Working on my first project with it now, coming from CX-series.  I have got one problem i can not find a solution to. On the NA-HMI I want to have an input display where i can input a time of the day.  As far as I can see NA do not allow me to use "TIME_OF_DAY" variables in the Data Edit component. Is there a solution to this? 

  3. Cycle Timer

    Andreas Rothe posted a topic in Omron

    Hi all, I try to realize a cycle timer. A counter is triggered by a movement ( clamp close ) Then the machine does it things, piston here, and there and when the clamp closes again it should show me the real cycle time. Is there a timer/counter that is independent from the PLC cycle? I am using a CJ1M CPU11 Ver. 3.0
  4. I would like to use the actual Cycle Time (in seconds) of the NJ101 CPU in a Structured Text  math equation.  You might also call it the Task Period... However it's called, It needs to be the amount of time that has elapsed from the last calculation of the ST math equation.  It must be a variable that also satisfies this looping equation: Time:= Time +cycle time .. so that the master equation, which is calculating position information, based on TIME .. is up to date with each calculation in the loop. How do I insert that cycle-time, which might not be identical for each loop, (or, is it) ?  Thanks, Regards, Michael  
  5. In my application the LMC automation controller will be calculating date-based lot codes. I would like to synchronise the internal clock with a time server such as pool.ntp.org. I can't find any info in the Schneider-Electric SoMachine help files or on the web. Does anyone know if this is possible?
  6. Hi,  i want to read real time and date in simulation mode. How can i do this in Unity pro? Thanks for helping
  7. Hello,     I am working in microprocessor industries, now I am doing reverse engineering for PPC SECS communication program in Visual C++ 6.0 for Mitsubishi PLC(Model Q50UDEHCPU). Did anyone from you have worked with this program PPC? I need to find out the what are doing each function from this program? Like hostproc, data, mainproc, otherproc, plcproc, qbproc queue, offline, send_c, QBFFunc32.

  8. Time Based Interrupt

    kav posted a topic in Mitsubishi

    Hello guys!!! My system constist of: CPU: Q03UDE Some I/O modules Some Intelligent Modules (Q68ADI,QJ71PB92V...) A High Speed Digital Input card QX80H (setting responce time 0.1msec) 1 digital input from QX80H occupied to count the pulse that a flow meter sends. The pulse corresponds to the totalizer of the Flow meter (FCI ST100 series Thermal Mass) and it has fixed width 0.5msec. The flow meter sends 4 pulses / minutes approximately according to current flow rate. My Main Program has scan time 2.4msec. I think that PLC ignores some pulses because of the pulse width is lower than scan time of my program. Is it right? So, the PlC program calculates wrong total flow.... What can I do to avoid this issue? Attached you can find a sketch what I mean... I though to program a time based interrupt every 0.3msec. Is it right and possible in Q03UDE CPU.....? If yes, how can to do it? Thanks a lot in advance for your any help!!!
  9.  Hi, im from brazil and need some help, some days ago i buy a programmer CQM1-PRO01-E beacause one plc CPM2B are deceased, we have another equipaments with this one, but CX programmer not response and de are trying day after day, but with this programmer i want copy and paste the logic from other PLC. Can you help with copy and paste on programmer CQM1?
  10. Hi everyone, I would like to create a PLC code using RSlogix 5000 program in order to measure time delays on the network. Can anyone help me to do this? Thanks.

  11. Help Programming a Beckhoff PLC

    jnatzic posted a topic in Other PLCs

    I have a very simple problem that I need help with.  I have some programming experience but I am brand new to PLCs and structured text.  I am using TwinCat 3 to program a Beckhoff CX9020.  My goal is to read the temperature from my thermocouple and open or close a valve based on the temperature.  I have successfully connected the PLC to the TwinCat software and I am able to see the value of the thermocouple increase and decrease when I touch it with my fingers.  I need to link that value to a variable in my code so I can have the valve act on it.  I don't know how to properly address the inputs and outputs.  Thank you!

  12. Looking for programmer help

    Jessica posted a topic in Siemens

    Hello, I am not sure if this is an appropriate place for this but we are a company that does electrical engineering for material handling systems in north Dallas, TX. We are looking for an experienced Siemens programmer to help train one of our engineers.He is writing a program from scratch and has not worked with Siemens before. We would need this person on-site for a few days to a week and they will be compensated as well as travel expenses paid. Our engineer will have very specific questions to ask as he is very experienced and has been doing this for many years- this is just a new system for him. If you are interested in this opportunity please contact me as soon as possible. 
  13. Hello, I got a new work job to design a cycle tester for a mechanism to make sure will work for at least 5000 cycles open - close. I never made a pls program I start researching few days ago and seams to be very complicate to make it. I have a TM221C16R PLC from Schneider. please help me with some instructions. the cycle tester will have a start pushbutton, stop pushbutton, door open switch, one air cylinder with solenoid to push and pull and a counter. Thank you, Romica
  14. Hi! I just started with PLC programming. I am trying to get the time between a output signal and a input signal. The problem is that the time is ~200 ms but when i measure it with this code:   TONR(Timer1); IF PosFeedback <= PosFeedback_Min & not Timer1.Reset THEN Timer1.TimerEnable := 0; FullCloseDeltaTime[1] := Timer1.ACC; Timer1.Reset := 1; END_IF; IF (move & not Move_LastScan) THEN //Start timer Timer1.TimerEnable := 1; Timer1.Reset := 0; END_IF; Move_LastScan := move; i only get even values in intervalls of 50 ms like 150, 200 and 250 ms. I have changed the real time sample rate to 11 ms so i don't understand why i don't get a more exact result. And i can see in my trend that the time isn't exactly 150, 200 or 250 each time. I i tried and time my own click on a button and i see the problem is the timer, i only get values in an interval of 50 ms. Is there a way to make the timer more exact?
  15. Hi all,  Can someone please help me, I am using a Micro830 Controller running connected components workbench software to program the controller. I want the use the Real Time Clock of the controller to control an output to turn on everyday at 01:30am and turn of when it receives a signal from an input. The output will control a backwash valve that will operate and activate a cam switch internally that sends a signal back to the Controller to say the valve has operated and can now stop sending the signal to the valve. (if that makes sense). I have tried playing around with the RTC instructions but I cannot seem to get it to operate how I want it to. Any help would be much appreciated. EnvrioService

  17. Hi, I am a beginner to PLC. I am currently working on a home project with Allen Bradley 1100 model. The project is to build a door open-shut cycle tester.  The motor I have purchased is a Bodine Brushless DC34B/FV INTEGRAmotor. My goal is to utilize the Allen Bradley to to control the motor and then the motor drive a shaft to open/shut the door. Through the LCD screen the of PLC, we can set and view the amount of cycles.  I have finished the initial stage of wiring. But not sure how should I start on the programming part. Could any of you give me any hints on the programming portion? Thank you so much. 
  18. hey!  I'm pretty new to PLC's, and I'm supposed to ''teach'' the people at my internship how this PLC works, but I have encountered a problem.  I've gotten pretty far with all the digital programming and understanding how everything works, but I just can't figure out how the analog inputs/outputs and programming works...... I've had a fair explaination on PID and how this works. I've searched the web as well to figure out what PLC instructions to use.    I hope you can answer my following questions.    1, what are the most used PLC instruction blocks which I can use for temperature control, and how am I supposed to use them? 2, Could you please give me an example on how to use PID and what numbers will I need for the calculations? 3, what are the most used PLC Instruction blocks (apart form the analog ones) that I should include in my tutorial?   this is my setup: Ethernet switch MOXA EDS-205 Plc voeding PA202 PLC CPU CJ1MCPU11-ETN Digital IN (16x) CJ1W-ID211 (SL) Digital IN (16x) CJ1W-ID211 (SL) Analog IN (8x) CJ1W-AD081 (SL) Analog IN (8x) CJ1W-AD081 (SL) TRANS OUT (16x) CJ1W-OD212 (SL) TRANS OUT (16x) CJ1W-OD212 (SL) Analog OUT (4x) CJ1W-DA041 (SL)   thank you soo much for looking at my question and considering helping me! the OMRON helpdesk hasn't been very helpfull.    kind regards,    Deuslupos,
  19.  hello there ! all the variables are reals ... can anyone explain why i get a different result when i calculate c2 first ??? the two programs shown in the pictures are exactly the same ... the only difference is the posistion of c1 and c2 . please help me . It's not a logic  attitude in programming ..... Any ideas? Thank you

  21. Hello all, I was asked to check if there is a PID real - time software which automatically calculates PID loops parameters and update the PLC registers or HMI ( by OPC server etc.) when the process is working and "breathing". REAL-TIME. Not PID simulator or PID tuner based on measured data, but a software that will calculate and update the PID parameters in real time while maintaning several PID loops simultaneously. Are there any suggestions? Thank you, Olesia
  22.   Dear, I need some help with an application in ml1500 with the RTC . I need an exit is enabled by days of the week . I´m programming in Rslogix500. Program follows the image. If possible help me. Thanks Daniel.

  24. Hello! I have a PLC S7-1200 (1212C DC/DC/DC) and a few question about programming S7-1200 in TIA Portal v13. 1. I want to make "upload station", because I am not surre whichone project is the last. But, when I start upload data, the error hapens, and the decription of error is: The name of the station "S7-1200 Station_1" is already in use in the project. How and where can I change it? 2. And the last question: I try to connect my S7-1200 and Weintek simualtion. There is all time :"PLC not connected". I have chceck everything: PLC is OK, communication PC-PLC ok (ping ok), windows firewall off, administrator rights ok, configuration made with manuals, (CPU - Siemens S7-1200, IP: 192.168.1.100, port 102, tags import - ok.) I have read the manual many times, and check settings - nothing change. Maybe have someone problems like this, and found a solution?

  25. I am converting a PLC-5-40 processor that also has a SST side car for Profibus Dp communication to BK3100 modules on the equipment. To a Control Logix L-72 processsor using a Molex SST-PB3-CLX card to the Profibus modules. Everything went some what smooth until I got to the SSI transducers in the Profibus. The word arrangement is not coming in the same as with the PLC-5. Is there anybody else that has run into this problem and is there a solution. I have contacted Molex, Balluff and Beckhoff the first 2 got back to me I am still waiting on Beckhoff.
