6.5.3.1 Global Network Parameters
In this screen you can modify the bus parameters for the whole network.
The screen is divided into three logical areas, as follows:
➣
Cumulative topology data
➣
Bus parameters
➣
Bus parameter data.
The first two areas contain information for calculating the default bus
parameter values. With F1 <Calculate>, you can obtain these default
values. The modified parameters are entered in the local databases with the
Network -> Network Matching function.
Select Edit -> Global network parameters to call the COM screen. The
screen has the following layout:
