Parameter

Meaning

 

 

Syntax

[192.11.2.34S7-300 Station (1)]

 

AbortConnectionAfter =0

 

 

Purpose

The parameter specifies whether and after what

 

waiting time OPC terminates an unused

 

connection.

 

 

Default

0

 

 

Possible Values

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.

 

 

Relationship between the Set Protocol-specific

Since the SIMATIC NET OPC Server can use

Cycle Times

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).

 

 

Example

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.
