Successful generation change at the automation level
Bustaffa
Cheese Factory
Italy
Saia® PCD6 controllers had to be replaced for the lat-
est generation following water damage at a cheese
factory in Italy. The requirement was to transfer the
applications program and the connection to the ex-
isting control system and renovate it without loss
of production. Owing to the compatibility between
generations of devices, the replacement work could
be carried out during operation, without stopping
production, and with minimal investment costs.

The PCD1.M2120 as BACnet controllers in air
conditioning units at Deutsche Telekom
The high-performance communication technology
at Deutsche Telekom has to be air conditioned round
the clock. To ensure the high availability of public tel-
ephone networks, all the relevant operating systems
and communications equipment are monitored.

Saia® PCD controllers record energy consumption
and control and regulate primary facilities. The in-
terfaces and various communication capabilities of
the new Saia® PCD1.M2120 were the deciding factor
when implementing a communications gateway. The
energy data is collected with the new plug-M-Bus
module and transmitted via fiber/WAN to the central
counting office.

Saia®PCD1.M2120 has been tested a thousand
times over in the field
The latest addition to Saia® PCD controllers, the
Saia® PCD1.M2120, sets new standards in the field of
small controllers. With USB and Ethernet as a stand-
ard communication interface, the large on-board
flash memory and the integrated automation server,
it provides small-scale control with unprecedented
functionality. In the year since its release, several
thousands of them are being used by customers in
a variety of projects. Owing to their compact and flat
design, they are used in the following applications:
in air conditioning equipment in small spaces, under
difficult environmental conditions in snow cannons,
in space control in a hospital, for controlling for cin-
ema projectors, in heat pumps, for building automa-
tion in a stadium, and in the control of solar and mu-
nicipal heating plants or as data managers and data
loggers for energy supply.
Saia®PCD1.M2160 with more memory
This CPU adds another device type to the young
Saia® PCD1.M2 family. This arose due to frequent
requests for even more onboard flash memory. The
CPU has 1MB flash memory for user programs, 1 MB
of SRAM for data blocks and texts and 128MB of on-
board flash memory for the data system. The fast CPU
combined with the large memory and integrated au-
tomation server makes it ideal for use as a data con-
centrator.
