  1. Delta Plc Solenoid Pulse

    Hi there, I'm working on a project on a cupcake machine. I have to throw empty wrappers so I'm using a photoelectric sensor to sense the empty cupcake and after 2.5-sec air solenoid activated with delta PLC to throw that empty wrapper. The thing which I want to discuss here is that I want to operate my solenoid with pulse means when the empty wrapper comes to the solenoid through the conveyor then the solenoid gives a pulse of air so the upcoming filled wrapped will not disturb with this air. how Should I program my delta plc it is a transistor base. Can I use PWM? Best Regards, Asad Raza
  2. Hello, I have a Sysmac project that contains two NJ controllers and an NA HMI. I am writing the current time to different variables upon completion of certain actions using the system variable _CurrentTime.  I noticed that one controller was logging the date as 1-1-1970, and went to sync the clock with my computer's clock via the Controller-> Controller Clock... menu.  Upon synchronizing and applying, the controller clock very briefly displays the correct time, and then reverts to 1-1-1970. I went to the second controller in the project, which simply had the wrong time zone setting, and attempted to change the time zone and apply. Whereas before it showed the correct time for the time zone setting, it now reverts constantly to 1-1-1970 as well. When I go online, I've also noticed the _CurrentTime variable is not incrementing; it is always 1970-01-01-00:00:00.00. The HMI displays the correct time, and I am considering creating a mapped tag that shares this time with the controllers, but was curious as to what could be causing me this issue. I am also aware that 1-1-1970 is the unix epoch. Any insight?
  3. Hello, I need to control a stepper motor(have stepper driver) using NX-PG0232-5 with NJ301 PLC. The function is simple, i need to run the stepper motor continuously at a specified velocity. So, in NX-PG module I've made the settings (Ch1 output mode as "Velocity continuous pulse output") and given the tags to IO (as shown below, sorry i'm not able to attach image). I've also added the initialization program to switch on the vfd. Now to move continuously i should should just give speed in pps in "PG_Ch1_Command_Velocity" right?      Ch1 Controlword    Control word 1    W    WORD                 Ch1 Switch On    Switch ON for pulse output 1    W    BOOL    PG_Ch1_SwitchOn        Global Variables     Ch1 Enable Voltage    Start turning on the power for pulse output 1.    W    BOOL    PG_Ch1_Enable_Voltage        Global Variables     Ch1 Quick Stop    Immediate stop for pulse output 1    W    BOOL    PG_Ch1_QuickStop        Global Variables     Ch1 Enable Operation    Start operation for pulse output 1    W    BOOL    PG_Ch1_EnableOperation        Global Variables     Ch1 Fault Reset    Reset errors for pulse output 1    W    BOOL                 Ch1 External Output    Aggregated data of external outputs for pulse output 1    W    BYTE                 Ch1 Command Position    Command position of pulse output 1    W    DINT    PG_Ch1_Command_Position        Global Variables     Ch1 Command Velocity    Command velocity of pulse output 1    W    DINT    PG_Ch1_Command_Velocity        Global Variables  
  4. Hi guys, I just starting to use Sysmac Studio. Its a bit confusing as I am currently used to CJ series PLC. Usually, we can use P_1sec, P_0_2s and so on to create a simple clock pulse timer function. However, I couldn't find the command or FB to do that in Sysmac Studio. Anybody could explain on how to do that in Sysmac? Thanks

  7. 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.

  9. Hi, I can’t find an answer to the following and I was advised to ask it here.I’m programming an Omron CJ2M with an MD212 high speed I/O card. I usually do all my programming in Structured text, simply because I like it a lot over ladder or sft.Now, if I want to read the hight speed counter (incremental encoder), I have to make a ladder section and use the PRV instruction to store the present value in a chosen location.The manual says the current PV is stored in A271, but I can’t get a readout there. Apparently the only way to read it is through this instruction.Does anyone know if there is an equivalent to the PRV instruction for Structured text? or another way perhaps? Again, when I check the actual memory adress, there’s no value there withouth the use of the PRV instr.
  10. Hello - I am currently setting up a program to control a downlane conveyor motor and ran into the issue of operators leaving the conveyor on through their breaks/at the end of the shift.... I know, shocking . Anyways, the essentials of the program are the following - ladder logic, start/stop PB station, a sensor that says when I've seen a box for x-amount of time I will turn off, when the eye is clear for x-amount of time I will turn back on. When trying to 'solve the problem' of the operators leaving them on, I figured this would give me a chance to use a RTC (real time counter) and program it so that at various times of the day I will send a single shot to verify the relay is CT is open. I've enabled the RTC on the Micro810, dropped a TOW but do not really understand how to set the TOW block up. Hopefully that all makes sense. Thanks,  grubb

  13. Hello, I have a cp1h-y20dt-d (sinking output) plc supposedly to be wired to a servo controller. The pulse control method is Pulse/Direction. I've did some manual research on the PLC and found the following diagram attached Untitled. Since the diagram above doesnt show which terminals does it connect to in the CP1H side circled red, I want to ask if those connections belong to the following diagram attached Untitled1? If so, assuming im planning to use only Pulse Output1 (Pulse/Direction method) from the PLC side, is the connection from the first diagram no.1=CCW0- , no.2=CCW1- , no.3=COM (connected to -ve) *Note: these diagrams are from omron's manual SYSMAC CP Series CP1H-X40D_-_ CP1H-XA40D_-_ CP1H-Y20DT-D CP1H CPU Unit Your replies would greatly help. Thanks and best regards, Summer
  14. I want to unify my programs and select only configuration words (the same program for many applications) . My problem is with the assigned outputs by the high-speed pulse output like PLS2, ACC, ORG ... I thing that the instructions JMP/JME may allows to use these outputs as normal outputs when HSPO functions is not required. Is it right ?
  15. Encoder Interrupt Help

    Hey guys, I am working on an application that tracks irregularly spaced PET bottles on a conveyor line and then blows them into boxes waiting on the side of the conveyor. I believe I have working logic, but I am having issues with the encoder at operating conveyor speeds. I believe the best logic for my project is to use a photoeye to detect the presence of a bottle (a one-shot makes sure it is only detected once), and then "store" the "presence" of the bottle in a binary file using an encoder pulse to trigger a BSL function. Using this logic, the bits in the file are analogous to a real, physical location on the conveyor, and I can just monitor specific addresses in the file where my real-world air nozzles are located. My current problem is that as my conveyor speeds increase, the PLC begins to miss pulses from the encoder. During my initial set-up, I took data at very slow speeds to experimentally determine how many pulses were between the photoeye and each air valve, but when I run at full speed, I only detect about 70% of the pulses detected at slow speeds. Not good. Althought the "skipped pulses" seem to be proportional to the detected pulses at slow speeds. I am using an encoder that only runs at 60ppr, so I would think that my PLC (MicroLogix 1200) can handle this...I did the math before I purchased the encoder and thought I found the pulses to be infrequent enough that the PLC wouldn't miss any. My 2 trains of thought: 1) I need to use an interrupt for each encoder pulse since they occur so quickly (utilizing an EII), which I am not fluent in. I can find instructions to intitially configure the EII file, but I am unsure of how you are supposed to correctly set up the ladder logic to utilize the interrupt. 2) There is an electrical issue. The encoder I bought uses pull-up resistors. The resistor value I selected only drops the detected voltage to 14V from 24V. Is it possible that the encoder does not spend enough time in the "off" state at high speeds because of this high voltage value? OR does the usage of a resistor introduce a time-lag into the system which further complicates the issue? Any help would be appreciated, Thanks!
  16. Hello! Does anyone have experience of using tooth gear pulse sensors. I am looking for this kind of sensor for the machine, we are building. My problem is that the sensor we are using is not suitable for North American markets (UL-standard is not aproved) and now I am searching sensor like this. I am not sure is inductive sensors good enough for measuring this, the one that we have been using is magnetic field pulse sensor.

  18. Micro 830 RTC programming

    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

  21. Version 1.0.0


    Updated Clock logic and HMI screen simple and well documented. To use this, 'Import' this 'Toolchest' Drawer file into your PMC's Toolchest. Then 'Copy' one of the Ladder Blocks into your 90-30 or PAC Rx3i Target by holding down the Ctrl key while drag-n-dropping it onto the 'Program Blocks' in the Navigator window. The QuickPanel Screen along with the 'Indexed Message Grid'  can similarly be brought into your QP or QP+ Target. If there is already variables in your project you may need to adjust some or all of those used here. The logic here also will help you to understand the Array_Move Function blocks in PME.

  23. Ladder diagram

    Dear guys, If anyone knows how to make a ladder diagram for measuring speed (RPM) of a rotating shaft (turbine). Here, a magnetic pickup pulse is connected nearby the shaft and , which gives i/p s to the pulse to the PLC. (Suppose, 25 pulse means one rotation ). So, guys pls post here the ladder logic diagram for the above application.
  24. Hiya Guys, New here (first post!) - and I'm fairly new to Connected Components Workbench, so apologies for the mammoth post! I am currently developing a System using one Micro850 PLC and one PanelView C600 HMI. I am able to update the current HMI time by sending Unsigned-Integers to Global Connection Tags: System Clock – Hour ($SysClockHour);System Clock – Minute ($SysClockMinute);System Clock – Second ($SysClockSecond);However, if using the same “update time” more than once, this method does not work as the HMI is looking for a “change” in a Tag before an update occurs (Tag-specific). For example, we require to be able to receive a “synchronisation signal” on a digital-input on the PLC each day at 15:00:00. This will only work once as, even though the HMI’s current time updates every second, I will still be sending the values “15”, “0”, and “0” to the above Tags (which will therefore not force an update – as they haven’t changed). I cannot reset these Tags without updating the current Time – as any number “out of range” causes an error (incidentally the errors are shown on the HMI to occur on Tags “SysClockSecondTimed”, “SysClockMinuteTimed”, and “SysClockHour” – note the omission of the word “Timed” on the Hours error…). There appears to be no reference to these “Timed” Tags anywhere in CCW, and I have no idea why the “Hour” update errors on a different (the correct?!) Tag. It’s a pretty confusing problem and difficult to explain… it took me a while to get my head around it – and I can see what the code is doing! J I've looked for documentation on how these Global Connection Tags work, but I can't find anything. Everything I (think I) know so far is from extensive testing... so if anyone knows of any documentation, or has any suggestions as to how I can achieve the required result - that would be massively helpful! Thanks for taking the time to read all this! Cheers, Steve.
  25. Memory M8011 - 5ms possible?

    Greetings! I just have one question. Is it possible to get pulse time down to 5ms? I have only been using down to 10ms so far. Im using the M8011 timer memory. Thanks in advance! Best Regards Henrik.
