Global Keys
The
Global Keys
folder can be used to assign tasks to global keys. Global
keys are running cyclic for the whole project. The following tasks are available:
•
Press Task
(tasks executed while pressing the key)
•
Pressed Tasks
, (tasks executed while holding the key)
•
Released Tasks
(tasks executed while releasing the key)
Please note that when key tasks are assigned to screen keys the global keys
will not be executed, e.g. global key F1 = add 1 to D000, and screen key F1 =
subtract 1 from D000 then subtract 1 is active for this screen when pressing
F1.
Tasks
On the
Tasks
dialog the
Power On
tasks and
Global
tasks can be configured.
The
Power On
tasks are executed once the NQ-Series starts up. The
Global
tasks are executed every cycle of the program. The task list can contain more
than one command.
Global tasks that most common used are:
• Switch SCREEN from TAG (used when the PLC is responsible for screen
switching).
• Copy RTC to PLC (this copies the NQ-Series’ RTC data to assigned PLC
tags (7 sequential tags)).
If the program contains many global tasks it can influence the performance of
the NQ-Series.
Tags
The folder
Tags
shows all tags that can be used in the project. The folder
contains the following tags: system tags (default set), internal tags (NQ tags)
and PLC tags created by users.
Tags represent the addresses
(bit, byte, word, double word registers) that will
be used in a project.
