10. Sub-network Monitor
10.1 General
The sub-network Monitor is intended to simplify configuration and troubleshooting of the sub-network.
Its main function is to display the data allocated for sub-network communication and detect if any area
has been allocated twice (i.e if a collision has occurred).
All configured nodes, and their transactions, are listed in the middle of the screen (B). Selecting and de-
selecting single transactions makes it possible to view any combination of allocated data.
Note: The sub-network monitor has a negative influence on the overall performance of the gateway.
Therefore the monitor functionality should be used with care.
10.2 Operation
A: Start Network & Stop Network Icons
These icons controls the sub-network activity. To stop all activity, click
on the red light. To start the sub-network again, click on the green light.
B: Nodes / Transactions
To view data blocks associated with a transaction, select the transaction in the list. The corre-
sponding data will then appear in the Monitor Section (C).
