| according to the following equation and entered: |
| l2_ttr = 9000 * [number of active |
| 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.
