Is the same as

The second module 11e sets t [1] of the cycle T as a communication time zone, and sets the remaining time zone as a transfer time zone. The third module 11e sets t [2] of the cycle T as a communication time zone, and sets the remaining time zone as a transfer time zone. The same applies to the fourth to n-th modules.
