Viewing this table for parameter setting:
First, determine the value of 2: BAUDRATE. Then, set the other parameters according to the set baud rate.
NOTE
For multiple master communication, satisfy the following conditions:
- The value set for 1:FDL ADD for a master station is not used as
another master station number.
- The same values are set for bus parameters 2 to 11 for all master
stations.
- When a larger value is set for T SET, T SL is larger than T ID1.
(T ID1 = 33 + 2 + 2 × T SET + T QUI)
