  9. Calculate Range (Scaling) GX IEC Developer

    A simple Function Block used to scale and unscale values.
    Input is in Integer format.
    Output is in Real format and also in Integer Format.
    Min and Max input values specifies the range of the input signal.
    Min and Max output values specifies the range of the output signal.
    Example:
    We have a 0-10V input module with a 0-6V sensor connected to it for pressure measurement.
    The sensors pressure range is -1,2 to 4,5 Bar.
    The Analog raw value is 0 to 16000.
    The settings should then be:
    "MinLimit_In" = 0
    "MaxLimit_In" = 9600 (60% of max input)
    "MinLimit_In" = -12 (Assuming we shall use Integer output and use one decimal)
    "MaxLimit_Out" = 45 (Assuming we .........).

  13. Configuring CC-Link

    Just a small introduction to configuring CC-Link...
    It doesn't replace manual it's just brief overview and
    short example how setup could look like on Q series PLC but
    this is very generic and most of it will apply to other platforms.

  16. QD75 Demo Program

    This file is a quick-start demo program for the Mitsubishi QD75M series of motion control cards. Many of the M bits (internal relays) were included for control from a simple HMI program (not included). I use GX Developer monitor mode to force the bits when needed.
    Please use the "Type QD75M Positioning Module" User's Manual (IB(NA)-0300062-B(0404)MEE) for reference. It is available from the "Downloads" section of Mitsubishi's website (www.meau.com).

  22. Pick and Place

    I just tried to contribute a little for our Mitsubishi section.
    This ladder code was written for FX PLC but it will work with
    little or no changes on any PLC. For those who don't have
    software I provided pdf version of the printout (it doesn't
    look nearly as good as on screen version but I don't have or don't know
    way to change that - i don't remember need to print plc program in
    such a long time...). Maybe someone will like screenshot version...
    Sequencer is counter based. This imaginary machine uses only three
    pneumatic actuators (gripper lift and transfer) with reed switches
    there is pair of photoeyes and it even controls two conveyors.
    Load conveyor runs until part reaches photoeye then it waits for
    pick and place to pick part. Unload side conveyor moves just
    enough to make room for next part and then stops.
    Program sections include alarms sequencer etc and has
    auto manual and step mode. Step mode is same as auto but
    intended for step by step execution which can be very handy for
    troubleshooting. I hope someone will like it because it took me
    nearly two hours to make darn thing and about half an hour
    to make those pdfs.

  24. Medoc sequence generator

    This software allows the user to select a particular program by activating a 24 VDC Ip In a Mitsubishi FX1s-30MR-Es/UL Plc .Now the user can choose different sequences in that particular program by using a momentary Pulse to a different Ip address to the PLC.This ip activates some Digital Outputs and deactivates some all this logic is in a continuos Loop and in a sequence as selected by the program.If in doubt or for any suggestions please get back to me !!!

  25. STL forward pause reverse

    a common use of plc's is for auto motor reversing with a pause between reversals.
    Common applications for this include mixers stirrers and in this case a dyeing machine that reversed water flowing through the material to ensure an even dye.
    it is written with some nice simple STL code for the auto reversing. It has auto/man mode with a routine to stop fast reversing in manual mode.
    It can be easily altered to impliment a timed or counted batch
    It is a nice example of simple STL programming.
    Written with gx developer V7 - i can convert to other version formats if requested
