Serial interface
The subassembly features two serial interfaces of RS232 standard. The can
be used for operating the PLC development environment, as monitor
interfaces and as client−specific PLC interface.
The signals are directed to 10−pole pin contact strips P1 and P2 and can be
connected via ribbon cables to the D−Sub plug connectors fitted to the card
slots or the PC housing openings.
The PLC programming environment can be operated at P1 with 115 kBaud
or via P2 with 38 kBaud. The monitor is actuated via P1.
A client−specific PLC program can operate both interfaces.
A standard null modem cable can be used to connect a PC. The handshake
cables (RTS, CTS) must be wired.
)
Note!
Use shielded cables and connector shells from metal or
metallised plastic for connecting the serial interfaces. The cable
shield must be connected conductively to both sides of the
connector shell.
