Tqui
The quiet time is the time a modulator needs after recognizing a send frame to switch from
send to receive.
0 t_bit <= Tqui <= MIN(31 t_bit, Min. Tsdr - 1)
Gap Factor
The Gap Factor determines how many token rounds occur before a new active node (master)
can be added to the token ring.
1 <= Gap Factor <= 100
Retry Limit
The Retry Limits determines the number of attemps (repeated message frames) allowed to
access a node.
1 <= Retry Limit <= 15
HSA
All active nodes (masters) scan the network continuously up to the HSA (highest station
address). HSA must be set at minimum to the highest profibus address (master or slave)
connected to the network.
0 <= HSA <= 126
Delta_Ttr
This value can be set for multi master networks with the selected profile Multi Master. Delta
Ttr is added to the calculated Ttr to increase the Ttr for using multiple masters in a network.
