7.2.3.4 Serial interfaces
Use
External units can be connected to the AC31 system via
the serial interfaces. The interfaces are independent of
each other. They can be managed via freely definable
protocols.
Scope of functions
The four serial interfaces can be configured independently
of each other in the following scope of functions:
·
Data format 7 or 8 bits
·
Even, odd or no parity
·
Discrete baud rates
from 300 Bd to 19200 Bd for COM3 and COM 4 and
from 300 Bd to 9600 Bd for COM5 and COM6
·
Automatic processing of the SW handshake
(XON/XOFF)
·
Automatic processing of the HW handshake
(RTS/CTS)
· Error detection
(parity, framing, overrun, break)
Serial interfaces COM3, COM4
Interface standard
– EIA RS-232 or
– EIA RS-422 or
– EIA RS-485
Both interfaces can be run independently of each other in
one of the interface standards each. Selection is by choos-
ing the corresponding interface signals.
Modes
– Programming and test mode
– Application mode
COM3 can be used as a programming and test interface.
Electrical isolation
Both interfaces are electrically isolated.
Connection
Connection is via a 15-pole D-SUB connector (female).
