  1. You seem to be mixing up contact and coils. Also in your second ladder rung you have two separate logic threads. Do not do that. Further, that second logic thread is screwing everything else up - you are forcing MB 3, O 2, and TD 1 on all the time. I would do that part this way: This is not clear to me. It looks like you've left out a step as you state that the first valve closes then you immediately say it opens again.

  2. Hello, I can solve my problem setting the G120 parameteres like the information of the table (parameteres marked in yellow) Best regards! Mario

  3. Hello, The observed delay is due to the fact that DTI file is now digitally signed. Starting from next UniLogic version (1.31), the "Store DTI to file" will include a new input controlling whether or not the file should be signed, which will give you a way to suppress that delay. Have a good day!

  4. Combine Aus idea with linearization, some compare nets and PWM can realase visual effect with normal blink, fast blink before end of time and constant LIGHT when time is over. As for me normal blink must be active at the all normal process time. Faster blink must be active only before time near finishing and this blink must not befaster then twice as normal. I build this idea on plastic welder machine. Only one GREEN LAMP and two button is present on operator panel of this old machine. And user know when process go to the end by fast lamp blink.

  5. Kratmel, I think the need is for the blink speed to increase as the timer runs. So as the timer nears finishing it is blinking quickly. Alighz, I would be doing this using a toggle coil whose input is controlled by a self-resetting count that reduces the reset number as a direct inverted linearization of the total timer time, as the time elapses. Also be aware that ideally you can't use a relay output for this, transistor output would be preferable. Plug away at that concept and see how it goes. cheers, Aus

  6. You can use PWM FB for generate different ON OFF condition for one output. You can manipulate PWM in range 0.0% ---100.0% (0--1000) and Duty Cycle in steps of 0.25ms (400=1sec). If you set PWM=500 and change Duty Cycle for example from 1sec (400) to 0.5sec (200) - you can see slow and fast blink. If PWM=0 lamp go OFF PWM=1000 - lamp go to constant light.

  7. Hi, When use mechanical switch, then it's contact(s) "bounce" when fast change it's position. Normal Digital Input has internal filter, which "neutralize" contact(s) bouncing.HSI has no such filters. You can use button on PLC display to start timer and generate fixed length output pulse. Use this pulse as input for high speed counter. Then everything should work as supposed. B.R.

  8. What is the I/O module the encoder is connected to? Typically on a V570 you use a Snap IO module which allows some of the inputs to be configured as encoder type. These are automatically high speed and take care of the rising and falling edges for you. Joe T.
