You can connect the BIxx/FIxx to a SIMATIC S5 programmable controller
via the COM1/TTY interface port.

follows:
1. Switch off the BIxx/FIxx.
2. Plug the cable into the COM1/V.24 PLC interface port.
!
Caution
Risk of damage to the BIxx/FIxx!
The interface port may be damaged if you confuse the connections or use the
wrong connecting cables. Make sure the TTY cable of the BIxx/FIxx is
plugged into the COM1/TTY port and not into the LPT1 port.
Before plugging in the cables, you must discharge your body’s electrostatic
charge by briefly touching a grounded object (ESD guideline).
Use only the original cables to establish the connection to the programmable
controller.
The BIxx/FIxx and the programmable controller must be operated at the same
protective ground potential.
An adapter is available for connecting the programmable controller using
older standard cables.
