  1. Hi Everyone,

    Learning the ropes of SoMachine V4.2 (coming from Arduino and Ucontrollers), I am using a Sequiental step style program and I am receiving 4 error messages. I'm trying to understand why it won't compile.

     

    1. POU for implicit check is missing. It is recommend to add the POU.
    2. C0032: Cannot convert type "IeSFc.SFCStepType(iesfc,3.4.2.0 (systen))'to type BOOL
    3. "Same error for a different ladder (the output of ladder rung hits the transition step, the transition is a bool which kicks off the beginning of another ladder rung).
    4. C0032: Cannot convert type BOOL to "IeSFc.SFCStepType(iesfc,3.4.2.0 (systen))

    Are these two different "data" types?

     

    Thanks in advance!

  3. Hi Everyone,

    I'm working on my first PLC program and I have gotten my hands on some ladder logic I'm trying to duplicate.

    I'm using SoMachine 4.1 and have started a new Ladder Logic diagram POU.

    I'm curious on how do I create internal contacts.

    EXAMPLE:

    24v--------l START BUTTON l----------------( COIL A)-----

    --------------l COIL A CONTACT 1; attached to a real output, solenoid valvel-------------l COIL A INTERNAL CONTACT TO CLOSE l----------------

    Are there standards for numbering and labeling?

    I'm seeing L and U inside coil contacts. Does this have an underlying meaning according to standard?

    Is there a RTO function inside SoMachine 4.1

     

     


  4. Hi Everyone!

    Where are my experts?

    I am undertaking a project at work. The project contains analog style motor positioning circuits (operational amplifiers, integrators, and other PI elements). Not that this is relevant to the post yet ;) .It's my first PLC project ever!

    I am using the Schneider M258 with SoMachine 4.1

    The PLC is talking to SoMachine via Ethernet (obviously I have a router between the PLC and my pc).I can Login and run the first POU I created. It's a simple And logic circuit for now.

    I have a co worker (c programmer) agreeing to help me pass data from my PLC to a browser screen. Although he's not familiar with PLC he's quite skilled writing code. He has wrote a Modbus protocol which allows him to interpret Modbus commands on his desktop.

     

    1) Do I Need any special hardware to pass the data out of the PLC into the Router then into his browser.

    2) As a trial can I send him MODBUS commands regarding my AND circuit?

    3) How do I create such a command?

    4) Is it possible for him to send me Modbus commands to change variables inside my program?

    5) Are there web browser "plug-ins" for this idea?

    Thanks for reading and hopefully all of you can help me answer some of these questions.
