The Global Node Number
The Global Node Number (GNN) is an ID number to identify Jetter controllers
(e.g. controllers, bus nodes) within an Ethernet network.
The GNN within a network has to be unambiguous for each Jetter device.
The JetSym Hardware Manager automatically assigns the GNN during
configuration.
The value range of the GNN within a project is 000 ... 199.
The controller has always got GNN 000.
The Global Node Number is used in the following applications:
Register number for network registers
Identification of publications and subscriptions at cyclic data interchange
Identification of nodes at automatic network configuration (NetConsistency)
The following illustration shows networking of a possible JX3 system with a
JC-120MC and two JX3-BN-ETH.
GNN = 001
GNN = 002
GNN = 000
