4.2.1
Ethernet network
ETHERNET 10/100/1000 Base T connection is the standard connection used on the Honeywell-
configured platform. An on-board dual NIC must be used for FTE configuration.
4.2.2
LCN cables
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 LCNP4e/LCNp4e2 board and the LCN
MAU is 2 meters in length.
4.2.3
LCN network
The connection to the LCN is made through a Local Control Network Processor (LCNP4e/LCNP4e2)
card. The LCNP4e/LCNP4e2 card is a Honeywell PWA that allows the TPS Operator Station to emulate
Universal Stations. This card provides the communication path for the Operator Station to other LCN
modules. The LCNP4e/LCNP4e2 consists of an LCNP4e/LCNP4e2 Card, a MAU cable and the LCN
MAU (Media Access Unit). The LCNP4e/LCNP4e2 card is a PCIe card and is located in PCI-ex8 slot 1.
The LCNP4e/LCNP4e2, MAU and MAU cable are required on Server Platform. The LCN node address
must be set to the address the customer wants. If the LCN address is not known then the node address
must 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 Honeywell server platform uses only a digital system clock. When the Dell
T320 platform is added to an existing system that contains nodes running analog clocks that system
must have at least two (2) KxLCN boards for analog/digital clock translation. The model number for the
LCNP4e/LCNP4e2 is TP-LCNP04.
4.2.4
LCN connections
The LCN Cable A and Cable B connections are made through a single cable from the LCNP4e /
LCNP4e2 board to the LCN Media Access Unit (MAU) contained in a metal housing. The following
illustrates a LCN MAU to LCN cabling.
