Lcn Network; Lcn Cables; Lcn Connections - Honeywell PE SC1430 Planning, Installation And Service Manual

LCN network

The connection to the LCN is made through a Local Control Network Processor
(LCNP4M) card. This card is a Honeywell card that allows the TPS Operator Station to
emulate Universal Stations. This card provides the communication path for the server to
other LCN modules. The LCNP4M consists of an LCNP4M card, a MAU cable, and the
LCN MAU (Media Access Unit). The LCNP4M card is a three quarter length PCI card
that consumes PCI-X slot 5. The LCNP4M, MAU, and MAU cable are required to
connect to the LCN Network.
The LCN node address should be set to the address the customer requires. If the LCN
address is not known, the node address should be set to zero (0). Setting the address to
zero (0) allows the node to be connected to the LCN without the risk of an address
conflict with some other node. This is consistent with the current LCN standard
procedure.
The server platform uses a digital system clock. When the server platform is added to an
existing system that contains node running analog clocks, that system must have at least
two (2) KxLCN boards for analog/digital conversion.
Note: LCNP4M card cannot be replaced with an LCNP4 card. The LCNP4M (model
number TP-LCNP02-100) is required.

LCN cables

Tower Unit
The two cables and T-connectors (and terminators, if applicable) must be located
underneath (the future location) of the unit, with an additional loop, 1 meter in length
(with a T-connector), to be routed into the rear of the platform where the connection is
made to the LCN MAU. The cable between the LCNP4M board and the LCN MAU is 2
meters in length.
Cabinet Mounted Server
The two LCN cables and with T-connectors (and terminators, if applicable) are routed
vertically inside the left rear corner of the cabinet (when viewed from the rear door) near
the vertical cable duct where the connection is made to the LCN MAU. The cable
between the LCNP4M board and the LCN MAU is 2 meters in length.
Refer to LCN System Installation, Subsection 3.6 for the rules and techniques of
installing an LCN cable system.

LCN onnections
The LCN Cable A and Cable B connections are made through a single cable from the
LCNP4M board to the LCN Media Access Unit (MAU) contained in a metal housing.
