Specifying Other Tags

It is good practice to enter all of the tags (variables) before you start programming. If you enter a rung with undefined tags, errors will be reported. At that point, you can enter new tags into the program and clear the verify errors.

In a similar manner as done for the I/O tags, type in tags for a few timers, counters, and booleans.

For timers, the data type is TIMER.
For counters, the data type is COUNTER.
For booleans, the data type is BOOL

Now the processor channel information must be specified.
