PCD web server
All Saia
®
PCD3 controllers and Saia
®
PCD3 RIOs come with an integrated web server
as standard:
●
Web browser as a tool for commissioning, support and visualization:
Access to the Saia
®
web server is via standard web browsers such as Internet
Explorer or Netscape Navigator. This makes the web browser, which can be
operated intuitively by anyone, the standard tool for commissioning, service,
support and visualization of machines, units and installations. The user can
retrieve pre-defined device and system-specific HTML pages, giving access to
all data on controllers and RIOs. Graphical elements (images, diagrams etc.) as
well as text documents (operating and repair manuals) can also be integrated
into the HTML pages, to provide a personalized user interface
●
General access to any desired interfaces and networks:
Access to the web server is available not only via Ethernet TCP/IP, but also via
cost-effective standard serial interfaces (RS232, RS485, modem etc.) and via
Profibus networks, throughout the system and at different levels in the network.
This makes it economical to use web technology to operate and monitor even
the smallest applications.
●
The Saia
®
PCD web server is integrated into all products:
Having a web server integrated as standard eliminates the cost of run-time
licenses or additional modules. In all new Saia
®
PCD3 controllers and the
Saia
®
PCD3 RIOs, the web server is already included in the base units, at no
extra cost.

General technical details
Supply (external and internal)
Supply voltage
24V DC ±20% smoothed or
19V AC ±15% full-wave rectified (18 VDC)
Power consumption
1)
PCD3: typically 15 W for 64 I/Os
Capacity of internal
5V bus
2)
PCD3: 600 mA
Capacity of internal
+V bus (16..24V)
2)
PCD3: 100 mA
1) The loads on the outputs are generally more significant for sizing the feed than the internal power leakage within
the controller
2) When planning PCD2 systems, it is essential to check that the two internal feeds are not overloaded. This check
is especially important where analogue, counter and motion control modules are used, as these may consume a
lot of power.
Atmospheric conditions
Ambient temperature
Mounting on vertical surface with vertically aligned connection
terminals: 0..+55 °C
In all other mounting positions, a reduced temperature range of
0..+40 °C applies
Storage temperature
-20...+85 °C (DIN 40040, class HS)
Relative humidity
30...95% without condensation (DIN 40040, class F)
