B Description of the PROFINET Configuration File
[192.11.2.34|S7-300 Station (1)]
AbortConnectionAfter =0
The parameter specifies whether and after what
waiting time OPC terminates an unused
connection.
0
0 – the OPC server does not terminate the
connection automatically (except when it is closed
down).
Higher than 0 – is interpreted as milliseconds, the
OPC Server terminates the connection as soon as
the connection is no longer used for this period of
time.
Since the SIMATIC NET OPC Server can use
variables of different protocols at the same time,
the maximum update rate of the OPC server is the
highest value set for the scan cycle time for the
active protocols (those for which connections are
configured).
A scan cycle time of 100 ms is configured for
PROFInet. No other protocol is being used. 100 ms
is used by the OPC server as the minimum update
interval. The S7 protocol is now added and the
scan cycle time configured for this protocol is 500
ms. Result: The OPC Server now uses the value
500 ms as the minimum update interval for all
protocols.
