6.5.3 Network Parameters
If you do not make entries in the network parameter screens, the COM
automatically enters the default values.
The network parameters are fundamental to the functioning of the whole
network and the individual stations. When configuring the network
parameters the following distinction is made:
➣
configuring global network parameters
➣
configuring local network parameters.
The "Global network parameters" screen allows you to edit the bus
parameters belonging to a network. These bus parameters are stored in a
file with the extension ".BPB". The screen can only be selected in the
OFFLINE mode. The edited parameters can be included in all the OFFLINE
databases belonging to the network using the function Network -> Network
Matching. The network matching ensures the consistency of the network.
The "Local network parameters" screen allows you to edit station-oriented
bus parameters. Local editing is useful for optimization.
☞
Remember that any input that is not compatible with the
network can reduce the performance of your network.
The parameters are only adopted on the CP during system start-up; i.e.
during the transition from the STOP to the RUN mode or after power up.
Parameters can therefore only be modified with the CP in the STOP mode.
