  3. I am running unitronics v280, v200-18-e5b, and io-d16a3-to16. I am wondering why the high speed outputs are different between the snap in and the expansion modules? In the hardware configuration the snap in asks for 3 operands and the expansion asks for only 2.    
  4. Unitronics 24V

    I have one PLC (transistor output) on panel with her 24V power supply. I have another PLC on panel with her 24V power supply. The distance between is 40 foot. I want send a output signal to one plc to another (with shielded cable). When I try I have only 9 Volts on the input. Why? How send and receive signal whiout communication? The 0V reference can be shared between power supply’s ? Thank you
  5. wich plc to chose?

    Hello all! I have one problem and i need an advice. I search for fast plc, that could have minimum plc cycle. I got 2 inductive sensors 0-10V (0.5 - 2mm). I connect this sensor with plc. On plc is connected shaft encoder which is 360ppr. My task is protech a stamping tool betwen stamping and if inside tool is some bad stamping pease we muss stop stamping. i control heigh of the stamping tool with inductive sensor. Right moment for measurement i get from incremental encoder. For example: I want to measure highof the tool at 90° - 180°, so when the tool if fully pressed. Now i have Unitronic plc with plc cycle cca. 2.5 mS and only one interrupt at 1.25mS and HSC interrupt at 359° (for reset at 0). But this plc is to slow for this application. Machine run at 200 rotations per munute, so i need interrupt less then 1mS (for one degree accurity). SO i need fast plc that can do those things fast. Most importanten is Analog to Digital conversion speed. Unitronics need cca 60mS for two analog conversion, this is too much. SO i need to do those things fast: 1. interrupt for hsc for set counter on 0 2. set interupt for hsc at 90° (at rising edge) (for high measurment 3. interrupt for analog input? I need fast AD conversion so that i can check for high of the tool every one degree. so which plc shuld i use?
  6. HELP

    Im new at this and just need some help. Im using a vision 130 with V130-33-TRA22. I have 1 push button wired in and two lights wired. I need to be able to push the button once and one light comes on then push it again and it turns off. Then push 3rd time and 2nd light comes on then push 4th time and 2nd light turns off. I cant figure this programming for the version 9.5 out. please help me with what to do for the programming.
