For any project, you must define the Tag database first. Tag is a register or coil which is used in
your application. Tags can be defined by using either Edit-Tag database menu or Tag tool. A
tagname can be assigned to each tag and the tag can be referred to by it's name subsequently,
making it very convenient to use. Tag database can be accessed from anywhere in the software.
It is advised to define all the registers/coils you will be using in your project ahead of time.
Once the Tag database is defined, assign the STR and the LED register. This can be done using
Edit-Setup menu or by clicking on the PLC-NT2S A link on the Toolstation. Use a bit addressable
register as the LED register so that each LED can be easily controlled.
H
ow are function keys configured?
To define the global task for the keys :
The NT2S A has 6 keys that can be assigned user definable functions by using the pull down
menu of Edit-Function keys or by clicking on the NT2S A key tool on the tool station.
The dialogue shows the function keys along with the user assignable legends. Click on the key
you wish to define, select the tag on which the key operates on and the action. Depending on
what type of tag ( bit or register ) is selected, only actions that can be performed on that tag will
be enabled.
DO NOT USE THE FUNCTION BUTTONS
FOR EMERGENCY STOP APPLICATIONS!
It is advised that separate switches be used
outside the PLC for ANY emergency stops.
