WARNING
This equipment generates, uses, and can radiate radio frequency energy and if not installed and used in accordance
with the instructions manual, may cause interference to radio communications. It has been tested and found to
comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules. These limits are designed to
provide reasonable protection against such interference when operated in a commercial environment. Operation of
this equipment in a residential area is likely to cause interference in which case users at their own expense will be
required to take whatever measures may be required to correct the interference.
SERVICE STATEMENT
Control devices are combined to make a system. Each control device is mechanical in nature and all mechanical
components must be regularly serviced to optimize their operation. All Landis & Staefa, Inc. branch offices and
authorized distributors offer Technical Support Programs that will ensure your continuous, trouble-free system
performance.

This manual should be used in conjunction with the System 600 APOGEE Field Panel User’s
Manual (125-3000). This manual describes the Operator Interface Program used to
communicate with the Open Processor and other System 600 APOGEE field panels.
In addition to reading this owner's manual, you should also become familiar with the
following technical documents. Each document has been written to help you get the most
use out of your Open Processor.
xPowers Process Control Language (PPCL) User's Manual (125-1896). This manual
describes PPCL, the language used to write the control programs for the Open
Processor.
xSystem 600 APOGEE Field Panel User's Quick Reference Guide (125-3001). This
guide is a pocket version of the Field Panel User's Manual written for experienced
users of the operator interface. It contains a listing of the operator interface prompt
strings and the keystrokes an operator needs to access the functions.
These manuals, along with information about other Siemens Building Technologies products,
services, and technical training classes, can be obtained from your local Siemens Building
Technologies representative.

Through the floor level network, the Open Processor establishes communication with and
gathers information about the Trane equipment it monitors and controls. Updated information
received from the Trane network is stored into a standard System 600 APOGEE point type.
The Open Processor also executes control programs, handles operator commands and
requests, and makes control management decisions.

The Open Processor samples the Trane network inputs, or points, for information and stores
numerical representations of these values. The Open Processor then takes the required
action; that is, it either adds current information to the history file or sends an alarm message
to the proper location.

The Open Processor continuously executes a user-defined set of instructions called the
control program. This program uses the most recent point values and the most recent clock
time. The control program performs the following functions:
xEvaluates control strategies.
xUses an internal calendar and time clock for time-based functions.
xUpdates point values, and commands field points according to the program results.
xSends alarms, messages, or reports to proper terminal locations as needed.

An operator can issue commands or requests to the Open Processor using an operator
terminal and the operator interface program that resides in the Open Processor. Reference
