System Configuration; System Pinning - Honeywell TotalPlant LCN System Installation

All LCN modules, hiway boxes, and peripheral devices require a unique system device address.

8.1 SYSTEM PINNING

There are no LCN module adjustments; however, the LCN I/O boards have an address
pack that must be characterized for the particular node it occupies on the LCN. This
normally is done for each system during factory test.
The address of the nodes in an LCN must start with "1" and be assigned in increasing
numerical order. In planning for future additions to the system, reserve a number or set of
numbers for that. All other addresses are assigned in the order of module placement.
Nodes can be added later during system expansion, and can be done so without changing
original assignments if gaps in the node numbering are placed to allow more node numbers
to be added later. At this time, a topology map should be initiated and maintained.
If the LCN I/O or K2LCN board is replaced on site, or if an additional module is added,
the new board or module (including the Universal Work Station) must be set up for the
node it will occupy; for example, Figures 8-1 and 8-2 show the location of the address
pack on the LCN I/O board and the K2LCN board, jumpered for an address of three (3).
The address pinning is logically ORed together if an LCN I/O board is used with a K2LCN
board. The address must be pinned only on the LCN I/O board and all jumpers removed from
the K2LCN board.
A Universal Station X node contains a WSI I/O board that is to be pinned as shown in
Figure 8-3. The WSI board has a Normal Shutdown switch that should be in the
NORMAL position. The SHUTDOWN position disables the Work Station Processor and
returns the node to a UNP personality.
An Application Module X node contains a WSI2 board that is to be pinned for used with an
HMPU processor or K2LCN processor. The WSI board has a Normal Shutdown switch
that should be in the NORMAL (to the right) position. The SHUTDOWN position disables
the Work Station Processor.
The Global User Station node number is configurable by software. Refer to Configuration
User's Guide, GU02-100.
