  10. Tracking product on conveyor

    By ParaffinPower

    Products arrive on conveyor irregularly pitched. Conveyor is equipped with an encoder or maybe a proxy looking at the sprocket.
    This program captures the position and then multiple FB calls can be made to give an output at a distance from the input point maybe at a label inspction point or reject unit.
    The Shift register readout FB can be called as many times as necessary.
    The encoder can be connected to a high-speed counter meaning that the PLC scan need not 'see' every number i.e the encoder counter can be asynchronous.
    I've simulated this in this program by incrementing the 'encoder' with a timed interrupt.
    Adjacent to the product position stack is a product status stack so data can be written in at any point too e.g. I'm in front of the label detect sensor - if it's on then I can enter a '1' (say) into the stack. As the status is kept in a Word then upto 16 devices can write into the stack. Subsequent writes are ORed with existing data.
    This can be achieved with FIFO but this method is more efficient as data is not actually moved just pointers to the data.

  11. Useable timer

    By ParaffinPower

    Hate BCD? Me too. Here's a timer FB that uses wait for it an INTeger preset.
    Easier to scale gives you the time remaining done bit and a timing bit.
    Use one of the system bits (P_1s etc.) to set the timebase.

  15. STUP Example

    By beegee

    This is an example how to change the port settings:
    in the example it is triggered by dip switch 6 (free use) and it changes the speed from 115200 for th HMI to 9600 for the modem. You could completely change the setup: check manual W393 section 7 PLC setup area
    Word 160 in the setup is here D6000 for the standard comms and D6010 for the high speed

  16. Omron CS1 Sequencer

    By neilr216

    OMRON CS1
    This is an example of a sequencer using a reversible shift register instruction
    Easy to troubleshoot because you can see what step it is on when the sequence stops for whatever reason.
    Easy to add steps and not too bad to insert steps.
    This program example shows the ease with which you can move to a specific step in the sequence after an alarm or stoppage.
