Suppose there are stations 2 and 10 in the network as the primary station, and the highest address (the station 10) is set to 15. For station 2, the so-called address gap is the range of 3 to 9; for station 10, the address gap is the range of 11 to the highest site 15, and also includes stations 0 and 1.
The tokens are transmitted between the primary stations in the network communication, and the communication activities on the entire network are separately controlled in a time-sharing manner. All the primary stations on the network will not join the token delivery ring at the same time, so it is necessary for a master station holding the token to periodically check whether there is a new primary station joining the site higher than itself. The refresh factor refers to checking the high site address after the token is obtained several times.
If the address gap factor 3 is set for station 2, an address in the address gap is checked when the token is received for the third time at station 2 to see if a new master station has joined.
Setting a larger factor will improve the performance of the network (because of unnecessary site inspections), but it will affect the speed at which new masters join. The following settings will improve the performance of the network:
1) Set the highest address closest to the actual highest site
2) Make all the master addresses consecutively arranged so that the new master detection in the address gap is no longer performed.
