Caution
Risk of damage to the device!
The interface port may be damaged if you confuse the connections or use the
wrong connecting cables. Make sure the TTY cable of the PC 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 PC and the programmable controller must be operated at the same protective
ground potential.
Connecting the SIMATIC PC via an Adapter
An adapter is available for connecting the programmable controller using older
standard cables.
