Hey guys, for an introduction to plcs, i have been thrown into the deep end and have been asked to design a program in zelio soft to operate an atm....
i semi grasp the concept, but it is starting to over whelm me and i dont know where to start...
i am in no way asking for someone to do this for me, just maybe suggest how to start...
here is the criteria...
This logic programme should enable a customer when permitted to enter an
authorised PIN, change it and dispense cash when permitted.
Only if access is permitted he/she can carry out withdrawal of money etc.
For this project it is enough the PLC based ATM
1. Recognises the Personal Identification Number (PIN) and grants access
2. Permits changing the existing PIN once access is granted
3. Facilitates selection of amount in multiples of $20/=
4. Issue Cash amounts if access is permitted.
5. For this project you may assume the customers can draw cash only in $20,
$50 and $100 denominations.
6. Resets the ATM back to its initial position once all the transactions are
completed for the next customer.
please any help is appreiciated....
