This section provides some general guidelines for adding points to the Open Processor’s
database. These points monitor and/or control Trane equipment controller operation. Define
only the points necessary for your application.

The following points are required in order to start up the Open Processor:
x
Add the Metapoint (FLN3, Drop 30) for each Trane BCU. Refer to the
BCU
Mapping/Metapoints
section for detailed information regarding the Metapoint.
x
Any LAI
NOTE:
Ensure that the Trane representative has set the network (ARCNET) address of
the BCU to the same value as the device address of the BCU.

Point Termination Modules (PTMs) are interfaces between the field equipment and the Open
Processor. Field equipment includes equipment controllers that provide information to, or are
controlled or monitored by the Open Processor. PTMs can also be controlled by Controller
Modules.
PTMs gather information from sensors. Sensors are
input points
because they provide
information, or
input
to the Open Processor. Sensors may indicate the position of dampers,
valves and other equipment. Sensors may also measure input such as temperature, relative
humidity, flow and pressure.
PTMs control equipment such as motors, pumps, fans, valves, dampers, lights,
compressors, and so on. These equipment controllers are
output points
because they are
controlled with electrical or pneumatic command signals, or
output
from the Open Processor.
There are 14 types of PTMs. Each has one, two, or four points depending on its type. PTMs
can be added to the MBC/RBC enclosure if the system expands. For more information about
PTMs, refer to the
Siemens Building Technologies Modular Building Controller and Remote
Building Controller Owner’s Manual
(125-1992).
