Abstract
The invention relates to a method and an electronic switching circuit for a scalable communication interface between a first communication connection (16) having a first transmission cycle (17) of a first length, and a second communication connection (12) having a second transmission cycle (13) of a second length, comprising a receive list (5), (7), (15), (19) for the first transmission cycle and a send list (4), (6), (14), (18) for the second transmission cycle, a data telegram (2), (21), (22), (23), (24), (25), (26), (27), (28) received according to the receive list being associated with an element of the send list.

Electronic switching circuit for a scalable communication interface (103) between a first communication link (16) having a first transmission cycle (17) of a first length and a second communication link (12) having a second transmission cycle (13) with a second length, with a receive list (5, 7,15,19) for the first transmission cycle (11) and a send list (4, 6,14, 18) for the second transmission cycle (13), wherein a data message (20, 21, 22, 23, 24, 25, 26, 27, 28) received according to the receive list (5, 7,15, 19) is associated with an element of the send list (4, 6,14, 18).
Method for setting up a communication interface (103) between a first communication link (16) with a first transmission cycle (14) of a first length and a second communication link (12) with a second transmission cycle (13) of a second length, wherein the first (17) and the second transmission cycle (13) are preferably synchronized with each other, and wherein the first and the second length are preferably identical or an integer multiple of each other, with the following steps:
- receiving a data message (20-28) according to a receive list (5, 7, 15, 19) associated with the first transmission cycle (17),
- transmitting the data message (20-28) according to a send list (4, 6, 14, 18) associated with the second transmission cycle (13).
