Token Group ID
The Token Group ID is the numerical identifier for a token group.
Each token group must have its unique Token Group ID.
Protocol Mode
Choose either Normal or RAW protocol mode.
Normal
In Normal mode, software token passing is ON, meaning that access
to the Ethernet network is controlled via token passing. Only the
controller that holds the token is allowed to access the network.
This mode is recommended for networks with slow hubs to avoid
message collisions.
RAW
In RAW mode, software token passing is OFF. No token is created.
Ethernet access is coordinated by hardware only. The affiliated Link
Mode is TCS direct.
