Technology:
using SNMP in automation
The AutomationServer functions are now used in
almost all projects with Saia® PCD. This offers ma-
jor benefits for the system operators. Following the
success of the concept, the AutomationServer was
upgraded to include further standard technologies
from the world of IT such as an SNMP agent (Simple
Network Management Protocol).
AutomationServer
The successful concept is further developed
A lean automation device has to adjust to the operator and user’s existing operating
resources and ensure data exchange without a need for proprietary hardware or
software. In the Saia®PCD automation stations, this is ensured by the Automation
Server, which acts as a form of universal access to make all the data externally available.

HMI, control and management functions
are integrated into the automation device
The prefabricated objects and templates enable the
efficient use of the AutomationServer functions.
Appropriate automation functions are available for
all the server modules such as the web server, FTP
server and SMTP client. In addition to the standard
control and regulatory functions, HMI and manage-
ment functions can also be directly conducted in
the controller.
Examples in this regard include the integrated
alarm manager and the trending module. Alarms
are recorded and managed in the controller and
not in a PC-based management system. Process
data can be directly displayed in trend curves from
the controller and archived in Excel-compatible
CSV files on the large Flash memory modules. The
functions are realised quickly and easily with the
appropriate FBox function libraries. In addition
to the PLC functionality, the application objects
also contain the applicable web-HMI templates,
which can be displayed with a PC with a standard
browser or with the Saia®Micro-Browser web
panels. In many cases, this makes additional,
external PC-based SCADA systems redundant.
Furthermore, all data are always stored on-site in
the controller. No information is lost even if the com-
munication with the higher level PC system fails.

AutomationServer now also
available with an SNMP
agent for integration into
IT management systems.

Saia®PCD with AutomationServer
Optimum integration of the AutomationServer
combined with powerful control application
The AutomationServer offers vital automation device
functions, making it an integral part of all Saia® PCD
control systems. It incorporates common web and
IT technologies and forms the open interface to
the user and operator’s tools and platforms. How-
ever, the AutomationServer with Saia® PCD offers far
more than just an open interface. Specially adapted
automation functions and objects form the perfect
counterpart for control uses. Only with these can the
AutomationServer be optimally and seamlessly in-
tegrated into the Saia® PCD automation device and
efficiently used.
