menu command to activate online access.

Note
To operate several diagnostic connections at the same time, you can start STE
P 7
special diagnostics more than once.
You can also start STEP
7 special diagnostics twice with an online connection to the
same CP; this can, for example, be useful if you want to monitor the diagnostic buffer at
the same time as running diagnostic funct
ions on a connection.
Requirement: You have an online connection available via the LAN (ISO or TCP/IP) on
the one hand and an online connection via the communication (K) bus on the other
(alternatively via the CPU or via PG channel routing via a further CP
).
