16.1 PTP network connection
The functions described in this section (software installation/update) require a
network connection to an external computer (PG/PC) which contains an en-
abled network access directory.
If the SINUMERIK 840Di sl is not part of a larger network (WAN, LAN), a simple
PTP (peer–to–peer) connection via Ethernet and TCP/IP can be established for
service applications.
16.1.1 Establishing a network connection
For the network link, the PCU 50.3 is connected with the external computer di-
rectly via a crossed Ethernet cable (twisted pair crossed 10baseT/100baseTX
Ethernet cable).
