SOI-to-PLC Communications Cable Requirements
For communications, a SIMATIC S5 programmable controller contains
a single programming port (which may also be used for point-to-point
communications, as supported by the S5 protocol). The programming
port is a female 15-pin D-sub connector configured as a serial digital 20
mA current loop interface. To communicate with the SOI, a special
cable is required to convert the 20 mA current loop serial data to the
RS-232 levels that can be interpreted by the SOI.
Using the SOI-260’s Optional Printer Port
The SOI-260's optional RS-232 printer port may be used to output
Printer Forms to a Printer or other serial device, such as a large ASCII
display unit.
The following configuration illustrates the cabling to be used.

ASCII Input
The SOI-260’s optional RS-232 printer port may also be used to accept
ASCII data from a variety of devices, including decoded bar code
scanners. The ASCII data can be entered directly from the device into a
standard data entry screen (configured using the SOI-SPS programming
software).
