505–2571 Module Description
1-2 SIMATIC 505-2571 Program Port Expander Manual
The
PPX:505-2571 Program Port Expander Module is a member of the
communication family of I/O modules for the Series 505 programmable
controllers. The PPX:505-2571 is a single-wide, Special Function module
that provides four additional communications ports that function like the
program port provided on the CPU front panel.
Ports 1 and 2 have an electrical interface that is a subset of RS–232C using
a male DB9 connector
. Ports 3 and 4 provide an RS–422 electrical interface
using a female DB9 connector. Both interfaces have been chosen to match
the programming ports provided on the SIMATIC 545 programmable
controller
. Thus, commonly used cables can be used with the PPX:505-2571.
The ports may be configured to support baud rates of 1200, 2400, 9600, and
19,200. All four ports may be used simultaneously with a combined
aggregate baud rate of 38,400 baud (for example, all four ports at 9600
baud). The PPX:505-2571 has two communication indicators for each port,
one for transmit and one for receive. These indicators light when
communications activity is taking place.
The red ”Active” indicator is used to indicate module status. The indicator is
illuminated when the module is functioning properly
. See the
troubleshooting section for additional details.
