3.2.1 Serial interface
The subassembly features two serial interfaces of the RS232 standard. The
signals of the first serial interface are connected to the RS232 plug
connector, and those of the second interface to the free contacts of the CAN2
plug connector. There are no hardware handshake signals for the second
interface.
The PLC programming environment and that of the internal monitors is
operated with 115 kBaud via the "RS232 connector. A client−specific PLC
program can control both interfaces.
