PXC Modular Expansion Module
The PXC Modular Expansion Module (see Figure 4)
provides the hardware connection for Field Level
Network (FLN) devices.
Using the Triple RS-485 Expansion Module, the PXC
Modular supports one RS-485 network of BACnet
MS/TP devices (see Figure 5). With the Expansion
Module the PXC Modular can also provide wireless
FLN support.

Modular Control Panels with
Application Flexibility
The PXC Modular is a high performance controller
with extensive flexibility. It can be customized with the
exact hardware and program for the application. As a
result, the user only purchases what is needed.
For example, in monitoring applications, the control
panel can be customized with the number and type of
points to match the sensor devices. For monitoring
and controlling a large number of (on-off) fans or
motors, more digital points can be added (see Figure
6).

and TX I/O Modules.
Alternately, if no local point control is required, the
PXC Modular can be used to monitor and control
Field Level Network devices using the Expansion
Module (see Figure 7).

Of course, the PXC Modular can be used for both
direct point monitoring and control and as a system
controller for Field Level Network devices (see
Figure 8).

Power Supply, and TX-I/O Modules.
In a stand-alone configuration, the PXC Modular can
fulfill all requirements of a supervisory network
coordinator by managing operation schedules and
alarms and communicating for the connected
devices.
The control program for each field panel is
customized to exactly match the application. Proven
Powers Process Control Language (PPCL), a
“BASIC” type programming language, provides direct
digital control and energy management sequences to
precisely control equipment and optimize energy
usage.
Available Options
Launch Pad
Siemens Launch Pad provides easy access to the
applications required for configuring, monitoring, and
controlling the Building Automation System. It allows
you to deploy the Application MC tool to a field panel,
load licenses, add shortcuts to other applications, and
access user documentation.
