• Be able to discuss the issues relating to the hardware software boundary and its implications.

  1. ASSIGNMENT DETAILS

1.2.1 Application Development

The ATM controller simulates the control system of an Automated Teller Machine. The user interacts with controls and indicators on the front panel to perform common ATM functions such as deposit funds, withdraw funds, and inquire about the balance of funds from the user account.

The ATM controller has access to user account information stored in the Accounts.txt file. You, the developer, are responsible for creating the Accounts.txt file, which the ATM controller reads from or writes to, depending on user-initiated transactions. Refer to the ATM Accounts File specification section for more information about the initial content and data format of the Accounts.txt file.

• Monitor user inactivity and terminate the user session after the specified time expires.

1.2.2 Sequence of Operation:

• Start (Application Run):

After the user completes keying in the account number and presses the Enter (E) button, the ATM controller should access the ATM Accounts file and verify that the account exists.

If the account does not exist, the ATM Messages indicator should display the Account Verification Failed Message and prompt the user to re-enter the account number.

• Withdraw: Click the button next to the corresponding Right Menu item. This action should display the Withdrawal Message, focus the cursor to the User Input control, and allow the user to enter the amount to withdraw from the account. After the user enters an amount in the User Input control and presses the Enter (E) button, the ATM controller should check if the account has sufficient funds to complete the transaction.

If the account has sufficient funds, the controller should deduct the keyed in amount from the current balance, update the ATM Accounts file with the new balance, and display the Withdrawal Complete Message on the ATM Messages indicator.

• Balance Inquiry: Click the button next to the corresponding Left Menu item to get the current balance from the ATM Accounts file. The ATM Messages indicator should display the Balance Inquiry Message.

• Return Card and Terminate: Click the button next to the corresponding Left Menu item to terminate the user session. The ATM Messages indicator should display the Session Terminate Message. The ATM controller should release the Card Simulator button to indicate the return of the ATM card, disable the User Input control, and terminate the application.

ASSIGNMENT requirements

• Conform to Labview coding style.

• Be created expressly for this assignment using Vis and functions available in LabView.

• • Labels on appropriate wires within the main Vi and sub Vis.

  • Description for each algorithm used.

• The documentation should cover the design, specifications and purpose of the functions used in the system.

1.4 DOCUMENTATION STRUCTURE

You must also document your system by writing a properly referenced report, which includes the following sections:

3. Description and Justification

3.1 Design of the Front Panel along with the purpose of controls and indicators

Printing Details

The report must be written using Microsoft Word, with the following specifications:

5. Margins are 30 mm. from left and 25 mm for the other margins.

6. Paper size is A4, using one side and leaving the other side blank.

1.5 Items to be submitted

You should use as many of the statements given throughout this module as possible.

1.6 ASSESSMENT CRITERIA

1.7 Plagiarism warning

Summary

• Plagiarism occurs if you use somebody else's work in an assignment or exam answer, but fail to state where you got the material from. You need to be also very careful about the amount of words you are using from somebody else’s work.

The details

• Copy extensively from the work of others (from sources such as books, magazines, journals, web-sites for example) and submit the work as your own. NB It is acceptable to refer to the work of others as long as you do not use too much, and reference your sources properly.

• Copy another students’ work and submit it for assessment under your own name.

THE RISKS OF WORKING WITH OTHER STUDENTS

The picture is complicated and, unfortunately, it is not possible to give advice that is directly relevant to every module you study. If you are unsure about how to avoid plagiarism in any specific module, then rather than hoping and guessing, you should ask for guidance from the member of staff who delivers that module.

Our overall advice is straightforward; by all means discuss how best to answer questions or complete tasks with your colleagues, but when it comes to actually writing your answers - DO IT ALONE!

What happens if you get caught?
