Interface characteristics
INTERBUS interface
The INTERBUS interface physically corresponds to an RS422 interface. It is char-
acterized by the following features:
Protocol
·
Transmission of the INTERBUS protocol
Transmission rates
·
Transmission rates:
500 kbit/s with INTERBUS and
0 to 500 kbit/s with RS422 - systems
Cable connection
·
4-wire
Range of operation
·
Can be used for:
- bus operation (INTERBUS)
- point-to-point connection (RS422)
·
