  1. 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    
  2. 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"?  
  3. 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 
  4. 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?  
  5. 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
  6. 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.
  7. 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?
  8. 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!
  9. Use to working on DC inputs, now I have a PLC I am playing with and the digital inputs are AC, can I still just wire a on/off switch to complete the circuit just for testing? This is a micrologix 1100.
  10. DIY CO2 Controller

    Guys, I find CO2 controllers to be too expansive and ugly at 500 $ How can I Take a CO2 sensing chip read it it's signal compare the signal to equal or above a value turn on an AC plug (Type B) when below value, OFF when above valueBaiscally, I want to make a CO2 controller myself (soldering on board, buy individual components, put in a box) This will release CO2 in the room through a solenoid when below 1200 ppm, and shut off the solenoid when above 1200 ppm IF I'm on the wrong forum, could you advice where to ask ? Thank you ! Dominique
  11. I am aware that I can use a word lamp, set its display address to $SW10, and then on the HMI terminal screen, the image displayed will change depending on the language chosen. BUT when I change the language switch inside CXDesigner, the image shown in the designer area does not change. This is annoying because it means I have to go into "offline test" to check that my translation images (fancy text shown as a bitmap) are correct. Is it possible to make CXDesigner change the image shown, in the designer area, according to the language switch?
  12. I have found the switch (in the label tab of an objects properties) that allows you to store 2 or more different languages within the label of a button. Now I want another button, within the HMI, to set this switch to a particular language. How do I do this?
