  1. Hi, In our machine, we want the homing of linear axis to be - moving to reverse limit. In order to achieve that we connected positive limit to Enable_positive input, negative limit to Enable_negative input of MC_Power function block. We used MC_Home function block and assigned the negative limit to bCalibrationCam of home FB. Things were working correctly.  But one thing we noticed is if the axis is in synchronous operation mode(axis following another master axis), even the limit is engaged axis is not stopping. During discrete movement this was stopping. Is there any other way to configure limit switch in twincat3. 
  2. GT Designer

    I am newer to GT designer. Ive used it a couple times years ago but I cannot figure out how to create a 3 position switch and cant really find any info on it? Is there a special way to set a switch up so that eveytime the operator hits it it changes the state or picture of the switch from left to up then to right and back? im sure its probably just something that im not seeing in the properties menu but any input would be greatly appreciated. 
  3. Hi Experts, I would like to know is there any possibility to make a switch that can make exponential increment to a data. i know how to make a switch to increment data in fixed intervals with a switch but im trying to make a switch when you press it continuesly it should increase the gains rapidly over time. is this possible and if yes can someone explain me how? im attaching a sample image how i want to make two buttons to increase and decrease a data. thank you in advance guys. kind regards, sathu.
  4. Good morning guys,  in your experience what is the best way to syncrhonize a motor controlled in speed with an inverter and a motor controlled in position with a servo drive? Let me explaine better what is my situation: I have a belt running normally at a certain constant speed. in some moments, I would like to syncrhonize the speed according to an axis controlled from a servo. the command of a servo specific position target and of course speed and acceleration e deceleration rate. I would like to adjust the belt speed in way to follow as accurately as possible the servo movement. Thanks a lot Andrea

  8. Switch LAMP latch

    Hello  I'm new with GT Designer 3, I'm writing code for a GOT2107 HMI. I have a few buttons that when you press it, the LED on the switch comes on, and when depressing the switch the LED goes off. That's good, but how do I create a latch, that when the switch is pressed and depressed, the LED will stay on. and only go off after the next press and depress?   The attached image is my working switch button. Regards Marinus    
  9. I have a Modicon NOM0200 unit connected to an access switch to send commands to various rs-232 devices. The Access switch requires a "disconnect string" to end communication with a particular port. The disconnect string is "CRTL+D", how can I send a "CRTL" keystroke from the NOM0200 unit? I know for carriage return it is "$R" is their a similar combination I can enter for "CTRL"?  
  10. Ethernet/IP bandwidth

    Hello, A while ago I modernised a magazine gathering / filmwrapping machine. This was a fairly big project for which I used an Omron CJ2M as the main PLC, 10 Wago Ethernet/IP fieldbus couplers, a Keyence CV-X420 vision camera and an Omron NS12 HMI.  All of these components run on the same network which contains an unmanaged switch where the HMI, PLC and the first Wago are connected. The Wago’s act as a two port switch since they are all daisy chained. At the end of the Wago chain there is also the vision cam which is connected at the last Wago coupler. At the time I was advised against using Broadcasting instead of Multicasting with a managed switch, but I tried anyway since my networking knowlege is lacking. Also, the only ‘bandwidth demanding data’ comes from the vision system. The Wago couplers contain only digital I/O and high speed encoder inputs run directly to the CJ2M. I haven’t run into any trouble so far and the machine is already producing for over a year. Now , a new project is on the way and it will need even more Ethernet couplers, 15 to be precise.  This brings me to my question; is there a limit to the number of nodes in an Ethernet/IP network and will I possibly run in to bandwidth problems by adding more remote I/O and not using a mannaged switch? Also, I would like to get high speed input out of one of the Wago couplers. Thanks in advance for any feedback! Greetings from Holland Andy 
  11. Hello, My apologies in advance if this is in the wrong place. I am working on a press that is using a 1746-INT4 to look at the position of the ram.  The press is using an LDT as the sensor reading back to the INT4. It obviously works. The press runs everyday.  I'm wondering if there would be a reason to use this instead of just a voltage or current analog card?   Thank you in advance for the replies.
  12. Switch Superimposed Window

    Using GS2107, FX5U. I want to change the JPG image on a screen based on if the value in a text box is either 1 or 2, any other value will also have a single default image. Is there a way to do this via script? Or is there a different way?  
  13. Hello - I've recently started my adventure into PLC programming and I've found this site to be very helpful. I took on a project that requires control of a cylinder - the short and skinny is that the cylinder will have to provide position feedback and stroke to various set lengths determined by position of a selector switch. So - If position 1 is selected, the cylinder will stroke 20"inches. If Position 2 is selected, cylinder will stroke to 25"inches - so on and so on.   My questions is how to best go about this process. I may be having a brain-block and not viewing this clearly, but something is not clicking for me and wanted some advice. Planned on using Allen-Bradley's Micro850 PLC (had one on the shelf, and CCW software is free so why not). Thanks
  14. Weintek hmi with fx3u128mr

    I have connected weintek 8103ie with fx3u 128m (Mitsubishi). The problem is when I create a toggle switch to hold an input on PLC it doesn't work. But momentary switch works properly. For eg. I want to keep input x1 of PLC on when I press a toggle switch. Also I want to run a coil when I hold a touch input. I can't achieve this in ebpro (IAM new to hmi ) but ok with PLC program.please help
  15.  Hi all. I have a question about how to set up the motor in rotary mode. My application will be a basic rotary table driven by a servo motor without gearbox between. So, in my servo drive axis settings, I select the motor as a rotary mode. then I defined the maximum position setting value for 360 degrees, and minimum to 0. So far so good. But the problem comes when I want to make an absolute move using the mc_moveAbsolute to move 360 degrees. Whit this settings the error "target position settings out of range " will come up. So, what is the solution to rotate 360 degrees without generating this error? if I set up the maximum value to 361 degrees and then if I rotate 360 the error will not occur and the motor will rotate 360 degrees as I aspected, but it's this correct ? or there is another way to do it? Thanks  
  16. I know it may sound stupid but I am new with Studio 5000 and trying to build a project where I have to home my servo drive other than the position to zero and it is not fix but rather decided by a safety switch. What I am looking for is a dynamic Home position Entry which I am able to find it in the axis parameter but not in the CIP_Structure. Is any kind of motion FB for home position set entry? Any help would be useful. Thanks PS: Studio 5000 v30, Kinetex 5500 v7.01, L33ERM processor
  17. Using Ethernet/IP to stream position data to a LinMot Drive, may be quite difficult because the LinMot requires a precise period between data points.  I've been told PVA streaming has been done with the Rockwell PLC, but the Ethernet IP bus needs to be updated at regular intervals (the requested packet interval between the PLC and the drive), and the task/ladder that has the streaming command is also examined at those regular intervals. This sounds like a timed messaging system over Ethernet, to satisfy the LinMot's requirement for precisely intervaled packets, which would compensate for Ethernet/IP's general lack of precise timing between data packets.     (the preferred method is to use EtherCAT) Has anyone ever tried this.. ?   Please describe the method with a little detail .. I'm trying to see if an Omron NJ can stream PV or even just P ... using their Ethernet/IP port.     If Rockwell has done it successfully, I would love to know how...   Thanks much... Regards, Michael
  18. I am searching for the Replacement of the Ultra 5000 Servo Drive as i cant get online to it with the Ultraware software over wireless plant network. In order to get online i have to connect serial cable every time. And the Drives are used in time critical assembly line  kind of environment. So is there any other replacement which works as intelligent as of Ultra 5000 and also have additional feature of built in Ethernet port which can help me to get online with it wireless over plant network.
  19. Omnuc U software

    Hi, I have begun to look into some positioning equipment we have had for a while. There is a CQM1 CPU51 connected to R88D-U series servo drives, and a CS1 with C200HW-NC113 and a R88D-U. I have found WinMon on myomron, but not tried to install it yet, will it run at all on a Win7 machine or do I have to dig out some older PC? Same with the NC unit, there is mentioned a SYSMAC-NCT program in the manual, but I have not been able to find this anywhere, Is this still a commercial item? Are there any newer software that will communicate with these old units? If we decide to upgrade any of this, will we have to replace all, or is it possible to reuse the servomotors or other parts? This is all for educational purposes, no production or safety issues involved. I would of course like my students to work with the most updated systems, but unfortunately we are on a limited budget :( Geir
  20. I am trying to learn the logic of a process at my new job. There are tag names that I can't make sense of because they end with _xva, _xvb, _xvu, _xvd, _xvo, _xvc, _zsm, _zsu, _zsc, _zso, _zsd and so on and so forth. I know they are associated with motion, but I need to make better sense of them. There are no descriptors. What do they mean and is there a resource available that I can reference?
  21. Hi all I am setting up a batch tank system, I have 1 pump which can pump to six different tanks(via pneumatic actuated valves). This is my first go with a HMI, usually I would use a multiple position switch. Is it possible to make a six position selector switch with a HMI? I am using a AB Panel-View 800, has anyone done this before? Any help would be appreciated.
  22. Hello everyone! I need your help.  I use the PLC: Q06UDEHCPU and the module: QJ71MB91. I programmed in the program GX Works 2 I instaled a library of "QJMB91ModbusSerial_V120 (FB - QJMB91ModbusSerialMaster)" and using it wrote temperature sensor interrogation program. The sensor is interrogated by the channel 2 and has the following switch settings:  Switch 1 - 0000; Switch 2 - 0000; Switch 3 - 0000; Switch 4 - 0A04; Switch 5 - 0000; which are specified by the PLC parameter in GX Works 2. I found an example of writing a program to install the switch settings in the user manual QJ71MB91 using ZP.UINIT instructions. I wrote a program to this exemple. Not prescribed bit address, which should be established when the program is executed (M0) (ZP.UINIT  "U4"  D0  M0). I wrote: ZP.UINIT  "U4"  D0  .  After executing ZP.UINIT instruction PLC stops working, blinking error, settings module is not install. How can I write a program to configure the Switch Setting?
  23.   In this first picture is a numerical input with a monitor device D2058. In the whole GOT project this is the only device that saves the information inputed.   Then on que PLC sequence theres an instruction moving that device's value gotten from the GOT to the position module's buffer memory. My doubt comes when there's another device D10022Z9 getting the same value of D2058. In this case the Z9 index is always 0, I checked. In the whole PLC program this is the only part where the D10022Z9 appears, there is no instruction anywhere copying D2058 to D10022Z9 which is how I would think is the way it has the same data always. Am I missing something or how is this possible?  
  24. I need to learn about position control for 2 axis with a QD75MH2 module. I know how the basics about programming with the Q Series PLC but I've never done any positioning control. I'm having a really hard time understanding the program I have to modify and I don't know where to start. Is there any course you might recommend? Even if I have to pay for it. Thanks.
  25. Program 16 position rotary selector switch

    I have a 16 position rotary selector switch I'm trying to program to a CQM1 PLC, that I will also be programming to a micrologix 1200 in the future, using CX Programmer. The switch connects to the PLC using 4 inputs, and activates the inputs in a binary pattern 0-16 as I turn the switch. For example: if the switch is wired to the first four inputs of the PLC, and is turned to "9" 0.0 and 0.3 will be activated and 0.1 and 0.2 will not, just like binary 9 = 1001. I have tried several things trying to get the PLC to accept these inputs as a single "data-point," and then convert to BCD or Hex to use in a timer. I'm having no luck! Does anyone have any ideas how this is done? The switch is a Tosoku DPP01 015L20RCB, and because of the age of the PLC my instruction set is limited. Thank you in advance!
