Q. What
are the main differences between XPANEL and SCADA communication?

 

 

A. Refer to the table below for advantages and
disadvantages.

 

 

 

 

 

Comm.

 

XPANEL

SCADA

Definition

 

 Communication
is based on

 Tag information entirely.

 

When an Xpanel
page is opened, every Tag on page gets involved in communication.

 

When a
page is closed, Tag does NOT get involved in communication. 

 

Tag registered
in Script, Alarm, Datalogging and DataServer features is always involved in
communication regardless of page status.

 

User can
define the communication blocks (at I/O Device) which are always involved in
communication.

 

Accordingly,
user must consider all Tag configuration before Comm. Setting and put them
into communication frame.

Advantages

 

Communication is
made without any specific Comm. Setting.

 

User simply registers
target device at   I/O Device.

 

 

User can define a
Comm. frame at I/O Device efficiently.

 

Without registering
any Tag, Comm. Block can only check the Comm. status.

Disadvant.

 

XpanelDesigner
creates its own algorithm based on Comm. frame, and this system cannot
control the Comm. traffic.

 

To run a
communication, there must be at least one Tag registered on Page, Script,
Alarm, Datalogging or DataServer feature.

 

 

 

Comm. Block must be
set up to run a communication.

 

 

If Comm. Block
setting is wrong, value in Tag might not be displayed properly.
