Automation station functions
These freely programmable automation stations provide the infrastructure for the
provision and processing of system-specific and application-specific functions. In
addition to the control functions, the automation station also incorporates
convenient integrated management functions such as:
 Alarm management with alarm routing throughout the network. Management of
simple, basic and extended alarms, with safe transfer tracking and automatic
monitoring of alarm transmission
 Time schedules
 Trend
 Remote management function
 Access protection throughout the network, with individually definable user
profiles and categories
The automation stations are freely programmable in D-MAP programming
language. This involves the creation of plant operating programs through graphics-
based interconnection of function blocks and compounds held in libraries.
Communication is via Ethernet with the internationally standardized BACnet
protocol. Both peer-to-peer communications with other automation stations and
connection to the PXM20-E operator units are supported.
The devices communicate via an open LonTalk system in accordance with the
international standard BACnet protocol. Both peer-to-peer communications with
other automation stations and connections to the PXM20 operator units are
supported.
The devices communicate via the public telephone network in accordance with the
international standard BACnet protocol.
Automation station operation
There are various options for the operation of the PXC…U automation stations:
 Local PXM10 operator unit, connected via a PXA-C1 cable
 Network-compatible PXM20 operator unit (BACnet/LonTalk)
for operation of the local automation station or an automation station in a
network,; connected via PXA-C1 cable
 Network capable operator unit PXM20-E (BACnet / IP)
to operate an automation station in the network, connected to an Ethernet hub or
switch
 PX-WEB: Optional web server via PXA40-W... option module.
Allows operation with a web browser, a touch panel or a PDA.
The transfer of alarms via SMS or e-mail can be configured in the automation
station.
