Chapter 1: Getting Started
Since a Timer is a structure it has predefined elements associated with it. Elements such as
.Acc (accumulated time), .Done (the completion bit) and .Timing (the timer is enabled and

of Do-more Designer will display all applicable bit (boolean) selections available for that
structure. Selecting the .Done option, as seen below, will assign this element to the contact
and the contact name will be T1.Done.
This feature works for all structures including: timers, counters, PID loops and strings.
Many system data types such as, $Main and $FirstScan, as well as user-created devices like
ECOM, CTRIO, or SERIO modules can also use this feature. See the Do-more Designer

checkmark in the upper left corner. Either

dialog seen here. Select the third option to

contact (C1) and select OK.
