6 Network Control Module 300 Series Technical Bulletin
• Intelligent Access Controller software integrates the IAC-600
access controller to the Metasys network, as well as supporting
XMs and HVAC ASCs (listed above) on the N2 Bus.
• As an alternative to the portable Network Terminal (NT),
Operator Terminal software connects a VT100 (or a Personal
Computer with VT100 emulation software) to the NCM. An NCM
with an Operator Terminal connected also supports NEUs,
Intelligent Lighting Controllers (ILCs), and HVAC Application
Specific Controllers (ASCs) (listed above).
In addition, an Operator Terminal connected to one NCM on the
N1 network can display, schedule, and control Fire, Access, or
S2 applications connected to other NCMs on the network.
The Migration Functionality builds pathways from the NCM to other
systems. While it can support any of the Standard Functionality
program sets described above, the advantage to Migration
Functionality is that it connects one of the following applications to
the Metasys system:
• S2 Migration software brings JC/85® field gear, object
information, and control directly into the Metasys system from the
JC/85 trunks.
• JC/85 Gateway allows Metasys object information to integrate
with the JC/85 Central Processing Unit (CPU). In the Gateway
application, the NCM serves as a high-level protocol translator,
making Metasys object information available to a JC/85 headend.
• The Network Port software lets you monitor and control the
Metasys system from a third-party host. The host computer can be
any of the many types that can communicate with an
ALLEN-BRADLEY® PLC-5® Programmable Logic Controller
(PLC-5 Family). The host, in turn, communicates with the
Network Port, which emulates some features of a
PLC-5 controller.
For complete information on the Network Port, refer to the Network
Port Technical Bulletin (LIT-6295050).
