Variables Exchange
Introduction
You can exchange variables with the XBT GT/GK HMI Controller range between
SoMachine and Vijeo-Designer by publishing them.
Controller and HMI Data Exchange
For variable exchange between the controller and HMI parts, perform the following
steps:
z Create variables in the controller part.
z Publish the variables by defining them as Symbols in the controller part. They
are now available in the HMI part as SoMachine variables.
Refer to SoMachine Single Variable Definition (see SoMachine, Programming
Guide) for additional information on how to publish variables.
Once symbols have been transferred toVijeo-Designer (the HMI part of your
application), it is usually not necessary to make the transfer every time you call
Vijeo-Designer. If you later add or modify symbols in your SoMachine application
after having initially transfered the symbols, you must again transfer symbols to
Vijeo-Designer.
Refer to SoMachine-HMI Data Exchange (see SoMachine, Programming Guide) for
additional information on how to exchange variables.
WARNING
UNINTENDED EQUIPMENT OPERATION
After adding or modifying symbols shared between the XBT GT/GK HMI Controller
and other controllers, you must:
z Update the Vijeo-Designer application,
z Download the updated application into the XBT GT/GK HMI Controller.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
