Help directories have been developed as an aid in using the industrial terminal.

They list the several functions or instructions common to a single multipurpose

key such as the [SEARCH] or [FILE] key. A master help directory is also

available which lists the eight function and instruction directories for the

Mini-PLC-2/15 processor and the key sequence to access them. The master

help directory is displayed by pressing [HELP]. You can press the [HELP] key

any time during a multi-key sequence. The remaining keys in the sequence can

be pressed then without having to press [CANCEL COMMAND].
