SIMATIC 505-2571 Program Port Expander Manual

If you require hardware handshaking for flow control, you should refer to
the device documentation for information on connecting the RTS, CTS,
DCD, DTR, and DSR lines. The PPX:505-2571 RS–232 port is configured as
DTE. In addition, you should set the port DIP switch position 3 to ON
(see Table 2-1 and Figure 2-1).

NOTE: Most common operator interface devices do not use the hardware
handshaking lines; therefore, you do not need to connect them. If you DO
NOT use hardware handshaking you MUST set DIP switch 3 to OFF
(see Table 2-1 and Figure 2-1).

First turn on the base power supply. If the diagnostics on the PPX:505-2571
detect no problems, the ACTIVE indicator will illuminate. If the indicator
does not illuminate or exhibits a blinking pattern, the module has detected
a component failure. For information on viewing failed module status, refer
to your SIMATIC TISOFT Programming Reference Manual. See Chapter 4
of this manual for troubleshooting information.

Next, check that the module is configured in the memory of the PLC. To
view the PLC I/O configuration chart refer to your SIMATIC TISOFT
Programming Reference Manual. See Figure 2-3.
