Definition of communication
Saia PCD® systems offer appropriate communication protocols to connect related building systems throughout the automation pyramid. The
greater the number of expandable communication interfaces, the more flexible and sustainable the automation system.
System selection
Communication re-
quirements as to the
number and type of
interfaces are largely
met by PCD2 and
PCD3 systems.
The PCD1, PCD2
and PCD3 have data
memory and file
systems.
In combination with
the «Device family»
selection, a choice
is made for the
Saia PCD3 system
family.
Description:
Two stage partial air conditioning system with
plate heat exchanger, air heater and air cooler.
Ventilation with manual/emergency operation. A
control cabinet is to be provided for the installation
of electrical and automation technology.
Controller:
TFlexible, modular and expandable controller
Interfaces:
TBasic interfaces – Ethernet / USB energy
measurement M-Bus; expandability option
Expansion reserve:
TAt least 20 % expansion reserve
Data:
TRecording/storage of operational data

Operating data is recorded/stored
on optional flashmemory (e.g.
PCD7.R551M04) according to CPUmodel.
Data is managed via the integral file
system.
An M-Bus connection to the meters of
various manufacturers can be integrated
into Saia PCD® systems via an external
gateway or with an integral interface
module. Integrated implementation
saves costs and wiring.
