15.1 PG Functions on the SINEC L2 Bus
The PG functions on the SINEC-L2 Bus allow you to obtain, monitor and
configure stations (CPs, CPUs) in the network topology from a central PG.
A link from a PG to the required station is known as a path. Using this path,
all the normal programming functions can be executed as if a direct
point-to-point link existed. The selected devices or CPs on the path are
known as nodes.
There are basically two ways of configuring a path.
The PG has only one AS 511 interface:
☞
If the end point is an S5-95U with a SINEC L2 interface and
there is no other station on the bus, it may not be possible to
establish the path on the PG interface.
