24.7 The Tags Button

On the Resource Information page is a Tags button. Selecting this button will display a list of general
purpose tags defined under the Isagraf5.Values node in the database. The values of these tags are
updated dynamically. New values for these tags can be assigned from this menu.
These tags are designed for use within ISaGRAF programs. They can be used for updating the status and
controlling set points of algorithms. They can also be added to a DNP or Modbus points list, thereby allowing
remote access to ISaGRAF functionality. The values of these tags can be read and controlled via the low-
level functions blocks defined in a previous section.

24.8 The Params Button

On the Resource Information page is also a Params button. Selecting this button will display a list of
configuration tags defined under the Isagraf5.Parameters node in the database. The values of these
tags are updated dynamically. The values of these parameters can be changed from this menu itself.
These tags are designed to be used as configuration parameters within ISaGRAF programs. They can be
modified via the Advanced screen by navigating to IsaGRAF5->Parameters, and will persist in non-
volatile memory. They can also be added to a DNP or Modbus points list, thereby allowing remote
configuration of ISaGRAF functionality. For increased readability and ease in understanding during
programming, ISaGRAF parameter descriptions can be renamed. These descriptions will be displayed in the
information screen. The renaming can be done via the Information screen or via the Advanced menu.
They can also be added to a DNP or Modbus points list, thereby allowing remote access to ISaGRAF
functionality.

24.9 Disabling ISaGRAF Resources

The user can disable ISaGRAF resources via the Info page. See section 5.4.3.8

Backing Up ISaGRAF Resources

All ISaGRAF resource and symbol information is downloaded to the /var/config/isagraf5 directory on
the MultiSmart. These files are all backed up to an SD card or USB whenever a full backup of the MultiSmart
configuration is performed. This is done by navigating to:
Restoring a saved configuration will also restore any ISaGRAF resource files.
It is also possible to restore only the ISaGRAF configuration files from an SD card or USB. This is especially
useful for deploying new ISaGRAF resources to existing devices. For example, if resources are compiled
and downloaded to one device, and then backup up onto USB, these files can then be transferred to other
devices via this functionality. This is done by navigating to:
