  5. Useable timer

    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.

  8. Tracking product on conveyor

    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.

  9. Toggle Button

    This program illustrates how to simply Toggle a bit on or off with a single input. (A basic flip flop if u like)
    Two versions are provided
    The first version will work in a CJ1 / CS1 PLC because of the direct diff funciton on the input bit.

  14. Sysmac Studio Simple PID Example

    A simple test program and starting values for the PIDAT instruction in Sysmac Studio. Simply run the simulator (Simulation-> Run) and toggle the Test_PID bit. Simulated feedback will allow the loop to operate normally. The setpoint can be adjusted by modifying the PID_SP variable. There is a pre-programmed data trace that traces the SP, MV, and PV.
    To use the data trace navigate to DataTrace0 and start the trace, flip the Test_PID bit true and the trace will log 10k samples. Change the SP and view the behavior when the trace finishes.

  15. STUP Example

    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

  19. Scaling in CJ1 CS1 PLC's

    The use of the old scaling functions SCL really suck when it comes to the new CJ1/CS1 PLC's mainly because it still relies on BCD etc....Today is so easy to use INT UINT values in the program i hardly ever use BCD any more.....

  20. Recipe Sample Code - Ladder program with supporting NB project

    This is a quick bit of code to show how a recipe function might be written if one were to do it in the PLC rather than the HMI. This is the basic building blocks with which a program could begin to be written. The BSET instruction combined with the indirect addressing method demonstrated would allow for a delete function. Copy and other functionality could be added using similar concepts.
