| Display all communication events |
Display device request and response in device folders.
If disabled then only errors are displayed. |
| Cache Data |
Enable device cache. The cache time is half the group
update rate. When multiple OPC clients or groups are
requesting the same data, turning the cache on can help
in reducing the traffic from the PLC. |
| Strict OPC RemoveGroup |
If disabled, the bForce parameter to IOPCServer::RemoveGroup call is
ignored. Some OPC clients incorrectly set the bForce parameter to
true, which causes the group to be deleted unconditionally even if
references (interfaces) to the group still exists, subsequent use of
such interface will result in an access violation.
If disabled, calls to IOPCServer::AddGroup with duplicated group
name, will cause that group and its items to be removed first.
|
| Shutdown when last OPC Client disconnects |
If IOServer is started by an external OPC client, IOServer will automatically shutdown when the last external OPC client releases it.
If this option is cleared, IOServer will not shutdown when the last
external OPC releases it. If IOServer is started manually by a user, IOServer can only be shutdown manually by a user. |
| Maximum System Time Offset |
IOServer uses the high
resolution timer (sub uS resolution) to keep track of time. IOServer
will synchronize its internal clock to the OS clock if the time
difference between the clocks is greater than the Maximum System Time
Offset. Use a value of 0 to stop IOServer from synchronizing its
internal clock. The message "System Time Offset" will be
logged to the ios.log file whenever IOServer clock is synchronized. |
| Keep last communication events |
Only the last "Trace List Height" number of
lines will be displayed in the Board->Port and Board->Port->Device folder. |
| Group Update Interval |
Use this default value for the group update interval if the user
creates a group with zero group update time. |
| SOE Interval |
Sleep for this interval after each advise to OPC
clients. A non zero value will slow down the performance of IOServer. |
| Max DNP3 Point Index |
Maximum DNP3 Index for all DNP3 Objects |
| Process Priority |
Run IOServer at Normal, High or Real Time process
Priority. Running IOServer at High or Real Time priority is not
recommended |
| Log File |
The location of the log file (Please send zip version
of log files, and .io configuration file when reporting
communication problems). The supplied readlog.exe can be
used to monitor the log file. |
| Keep Last N Daily Log Files |
The current log file is ios.log, the previous day log
file is ios.log1 and the last log file is ios.log6 (for N
equal to 7). Set to 0 to disable logging. A new log file is also
generated when file size exceed 100M. |
| Write Interval |
How often to flush the log data to disk. IOServer will buffer
up to 16K of data or when the write interval have expired. Using a
value of 0 will cause higher CPU usage. |
| SOE File Path |
DNP3/Kingfisher/Courier SOE log files directory path. Log files will be
created under this directory. Leave this field blank to stop IOServer from
generating daily SOE files. If a non-directory name is used, then all
SOE will be written to that file. |
| Communication Logging |
Log all communication events to the log file and port folders.
| Disabled |
Only errors are logged |
| Enabled |
All communication events are logged. |
| Auto |
Logging is individually controlled by the
"Log Communication" option in each port. |
|
| OPC Server Log Level |

and ios.log to ios.log1. Where N is the number of log files to keep. |
| Log OPC Read Call back |
Enable logging of Read Call back to OPC clients. |
