Ref.: IR14417 A 15.01.2018 Page 57/76
The communication cables must be shielded twisted pair. The signal pairs B1/B2 and
T1/T2 may not be exchanged; T1 connects to B1 and T2 connects to B2 of the next
module. The return signals (signal SI+-B) are only present if the hardware error detection
recognizes no error.
