Posted 27 Dec 2022 Hi New here. Trying to create a cumulative timer with zelio soft 2 for a SR2B201BD So, whenever the plc receives a pulse (coming from a coin acceptor) it adds x amount of time, whenever receives a second pulse, adds x amount of time to the time left on the timer. This is a timer for a self serve car wash. Used to work with Ecostruxture Machine and a TM221, but do to a stock break on the supplier and time sensitive project was forced to change to a sr2. Can't seem to make the transformation from my program on ecostruxtur to the zelio. Any help? Thank you Share this post Link to post Share on other sites
Posted 1 January Can you post what you have made so far?? I try to help you to do this to work. Share this post Link to post Share on other sites
Posted 2 January Sorry the forum isn't allowing me to put a jpeg of my timer done with Ecostruxture for a TM221. Basically, a coi acceptor sends a pulse to an input, everytime it's received adds 66 seconds on an operation block, when another pulse is receive, adds another 66 seconds (at this point there's 138 seconds) When another input receives an signal, the timer starts, when it reaches zero it resets. Wish I could post it to get the idea, it's a timer for a self service car wash 50 cents gives you x amount of seconds through a pulse 1€ gives two pulses (x+x) 2€ four pulses (x+x+x+x).

Posted 2 January (edited) Can you send me your e-mail for we can exchange ideias?? I think that you can't do it with this progamable relay, cause i can't see for now anything that alow you to change the value on the timer and/or counter, cause you can use a counter and a 1 secunde pulse generator. Do you have any experience with another type of plc?? Edited 2 January by rualcosi Share this post Link to post Share on other sites
Posted 2 January My e-mail is joao.palas@chempal.pt The plc is a sr2b201bd, it allows FBD programming, my experience is with TM221c24t in wich i have the timer made, that was what i was triyng to send. However can't seem to transform it to zelio soft 2. Share this post Link to post Share on other sites
Posted 3 January Consider restructuring your algorithm to use a fixed-duration timer and an up&down counter. The fixed timer would pulse the counter down and reset itself each time it completes, and only run when the counter > 0. The coin interface would pulse the counter up. The general interlock to the car wash would be counter > 0. Share this post Link to post Share on other sites
Posted 3 January Hi, Here is a beginning of solution based on the explanation of pturmel. I1 is the coin input and I2 is the start input of the cycle. V1 is a comparison of the counter > 0. https://ibb.co/LQvY1rd JC Share this post Link to post Share on other sites
Posted 8 January Just an update. With some of your ideias and member Rualcosi great help, I was able to do it. Wish I could post the final result but the forum doesn't allow me. Thank you all for your help. 1 person likes this Share this post Link to post Share on other sites
