  1. Swervo, there are so many different styles of schematics you'll have to decide in the first place which way you want to go. To me it is personal preference. There are different names world wide for different style types. I actually hate modern style "line diagrams", "riser style" as I find them counter-intuitive and hard to understand at a glance, as you need to constantly reference descriptions. I much prefer older style where the entire layout and connections are visualised. Sometimes these are called pictorial, maintenance, schematic. This link https://www.nrc.gov/docs/ML1025/ML1

  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. 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.

  4. 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

  5. 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.

  6. 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.

  7. Now in standard configuration you have only ONE com port1. This can be used for USB connection (Visilogic) or for Modbus connection via RS485. Simultanosly use for Visilogic connection and modbus is not possible for ONE port! Now after Ethernet card installation you can connect to Visilogic via Ethernet. Correct IP and PLC name must be entered to Visilogic Communication & OS settings. Then you can use PLC Port 1 for Modbus. Please note - RS485 must be set by jamper inside PLC. Correct wire A and B must be connected to RS485 port. Only after correct hardware setu

  8. I recommend to do table of component that you use in your installation. And sort it by manufacturers. Then visit site where this component (free or not) element database present, You can see what software is suported by manufacturers. Then try to check licences price for this software and futures provided.

  9. 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.
