Syntax | |
| 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 | 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. |
