This chapter deals with the Network Database - how to define it, how it is

used and what each entry means.

Information about the devices on your network is stored in the Network

Database.

Each device has an entry in the database containing

everything PCNC needs to know in order to connect to it and process its

alert messages. Current status information received from the network

itself is also stored. The contents of the database are displayed in the

Network Inspector window.

Each device is identified, both internally and by PCNC, using a unique

Poll number. However, PCNC allows you to assign a unique name to

each device in the database. This could be its location eg 'Glasgow

Depot' or anything else that will make it obvious which device it is. Once

the device is defined in this way, PCNC refers to it by name rather than

by its Poll number, making network supervision much easier.

This database is stored within PCNC, but is saved periodically (at

intervals defined in PCNC.INI) to a disk file called PCNC.DAT. When

you exit the program, the latest version of the database is saved. When

you reload, PCNC automatically reads the database back from this file.

It is a good idea to keep a safe backup of this file to ensure that
