Tag types
RSView32 uses the following types of tags:
Tag Type of data stored
Analog Range of values.
These tags can represent variable states such as
temperature or the position of rotary controls.
Digital 0 or 1.
These tags can represent devices that can only be on or
off, such as switches, contacts, and relays.
String ASCII string, series of characters, or whole words
(maximum of 255 characters).
These tags can represent devices that use text, such as a
bar code scanner which uses an alphanumeric product
code.
System Information generated while the system is running,
including alarm information, communication status,
system time and date, and so on.
RSView32 creates system tags when it creates a project.
The system tags are stored in the folder called “system”
in the tag database. You cannot edit system tags. You can
use system tags anywhere you would use any other type
of tag.
