● Up to 52 physical I/Os
● Integration of up to 5 subsystems, such as Modbus, M-bus, with up to 400
data points
PX Open
PX Open system controllers let you integrate third-party devices via Modbus,
M-Bus, KNX and other protocols. System functions, such as alarm
management, time schedules, trend data storage and flexible programming are
available.
Web interfaces and touch panels
The various operator units cover all the various requirements in terms of
location and function.
PXG3.W100-1 and PXG3.W200-1 web interface
The BACnet/ IP Web interface permits local and remote operation of Desigo
primary and room automation stations as well as third-party BACnet/IP
devices. The products PXG3.W100-1 and PXG3.W200-1 vary in functionality as
well as permissible system limits.
Use:
● Remote access to the plant
● Local operation using third-party devices
PXM30-1, PXM40-1, and PXM50-1 touch panels
The TCP/IP touch panels are used on projects that require multiple touch
panels or third-party devices to operate the same system data. The central web
interface PXG3.Wx00-1 can connect multiple devices.
Use:
● Multiple touch panels on a plant room, conference room, open office
spaces, etc.
● A touch panel in the plant room for on-site operation, remote access via
third-party devices
PXM30-E, PXM40-E, and PXM50-E touch panels
The BACnet/IP touch panels can be connected directly to the BACnet network.
No additional devices required to operate the Desigo system.
In addition, the BACnet/IP touch panel also includes a web interface for remote
operation using a standard web browser on third-party devices. The
functionality of the web interface essentially matches the functionality of the
PXG3.W100-1, differing only in the permissible system limits. The integrated
web access increases the competitiveness of Desigo on smaller projects since
there are no additional costs and installation effort.
Use:
● Very small projects: One touch panel for on-site operation of a primary
plant. Remote access occurs directly via the integrated web interface on the
touch panel.
● Large project with multiple, decentralized touch panels. The central, cross-
building operation takes place on Desigo CC.
