Communication
DP/MPI/PPI
RS 422/485
Connecting the PLC to a Basic Panel PN
CAUTION
Data network security for communication via Ethernet
End users are themselves responsible for ensuring security of their data network in
Ethernet-based communication, such as PROFINET IO, HTTP, Sm@rtAccess,
Sm@rtService and OPC, since operation of the device cannot be guaranteed if the device
is subject to targeted attacks resulting in overload, for example.

Meaning
No RTS signal on connector, for data exchange between
the SIMATIC PLC and the HMI device
(factory state)
RTS signal on pin 4, same as PLC,
for example, for commissioning
RTS signal on pin 9, same as for a programming device,
for example, for commissioning
RS-422/485 interface is active, for example, for
connecting PLCs of other manufacturers
Basic Panels PN can be connected to
the following SIMATIC PLCs:
