BRIDGE CS-L2

 

 

according to the following equation and entered:

 

l2_ttr = 9000 * [number of active PROFIBUS-TM stations].

 

Note: The factor 9000 in the equation only applies to a baud

 

rate of 1.5 MBaud.

All bus parameters are matched to a transmission rate of 1.5 MBaud.

Optimization requires detailed knowledge of the PROFIBUS standard, Part 1, DIN 19245. Selection of a different transmission rate is illegal, and may result in faulty functioning.
