Write options

This screen is accessed via the Controller | Write to the controller command. The lock and the password are independent of each others. Apart from the modifications authorised by the DISPLAY function blocks, the lock prevents the buttons on the front panel from having any other effect on the program. An optional password (number between 1 and 9999) chosen by the programmer provides read and modification protection of a program downloaded to the M2. After 5 unsuccessful attempts, the M2 starts an internal clock which does not allow a new password to be tested for a period of 30 minutes. A customer who has lost both the application chart and password can only execute the "Clear the contents of the controller" command.
