    Hi Joe, how are you, i have a project that uses the Unitronics HMI USP156B10 model. I want to display a stopwatch function onto the HMI. I am using ladder programming now.

    the process is like this:

    -user removed tool from sensor

    -start timer and records it

    -user place back tool

    -timer stops and display onto HMI

    Please advice, thank you

      I'd roll my own timer using a time pulse for more control.

      What time resolution do you want?

      How many recordings do you want?

      Have you tried something yet and do you have a program you can share?

    Good afternoon, Joe. Please help me.
    I use Unitronics V570-57-T20B. I need to replace the software. But I can not connect to it. It has a USB connector type B (square). The problem is to install the driver? Help me to understand.

      The square USB connector on a V570 was originally intended to be functional but was never implemented.  Was there a sticker over it?  The new V570s with a working USB port have a mini-USB connector.

      You will need a serial cable (MJ10-22-CS25) and a USB to serial converter (MJ10-22-CS35).  Then you access it via Port 1 on the side.

    Hello Joe

    I need a sample for Unitronics Sm43 for High Speed counter for measuring proximity sensor impuls ?

     

    Best regards

      Take a look at this.

      Can you be more specific with what you are trying to do?

    Hi Joe,Hope you're well.

    I'm still trying to figure out how to display an elapsed timer.

    Or rather how to start and stop one.I'm using a vision280 with a snap in i/o.

      Martin,

      Those SB's aren't for you.  Don't rename them.  They are System Bits and the PLC OS will stomp on them despite your logic.  Read through the descriptors and learn what they can do for you.  Use MB's for your own code.  

      Most timers are delay on timers, but there is such an animal as an accumulating timer (type TA) that will do what you want.  Read all the Help on timers.

      I've attached a simple example.  You'll see I've used a special coil called a toggle, which is kind of unique to Unitronics.  I have also assigned and MB to the Touch property to the rectangles.

      How did you come to start with a V280?  It's an older model and I never use them on new projects.  The Enhanced Vision series has a lot more power and is easier to work with.

    Re the MF, it would also be nice to know exactly what version it got dropped.  I haven't used them, but it would be confusing for those who have them in a program that then won't upgrade properly.

    cheers Joe

      I ran head-on into this when trying to interface a to a Watlow control.  Some idiot at Watlow decided that all numbers inside should be floating point.  Probably an engineer fresh out of school.

      Then to make matters worse the Endian is backwards from Unitronics.  I needed the Struct/MF to reverse the bytes.

      Gah!
