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).

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
Modules (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.
Global Information Access
The HMI port supports operator devices, such as a
local user interface or simple CRT terminal, and a
phone modem for dial-in service capability. Devices
connected to the operator terminal port gain global
information access.
Multiple Operator Access
Multiple operators can access the network
simultaneously. Multiple operator access ensures that
alarms are reported to an alarm printer while an
operator accesses information from a local terminal.
When using the Ethernet TCP/IP ALN option, multiple
operators may also access the controller through
concurrent Telnet sessions and/or local operator
terminal ports.
Menu Prompted, English Language
Operator Interface
The PXC Modular field panel includes a simple, yet
powerful menu driven English Language Operator
Interface that provides, among other things:
• Point monitoring and display
• Point commanding
• Historical trend collection and display for
multiple points
• Equipment scheduling
• Program editing and modification via Powers
Process Control Language (PPCL)
• Alarm reporting and acknowledgment
• Continual display of dynamic information
