  1. 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.
  2. 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?
  3. 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!
  4. 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.
  5. 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
  6. 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?
  7. 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?
