Cascade connection
SMO S40
F2050 (one or more) can communicate with control module
(SMO S40), by connecting the terminal block for communic-
ation (AA23-X4:1, 2, 3) in F2050 to the terminal block for
communication in SMO S40, AA100:X9-4(A), -5(B), -6(GND).

Addressing via cascade connection
On the communication board (AA23-S3), the communication
address is selected for F2050 to the control module. The
default address for F2050 is 1. In a cascade connection, all
F2050 must have a unique address. The address is coded
in binary.
