[ctrl]

Settings for the Control Manager

[ctrl] ctrlDLL

Type
string
This config entry loads a CtrlExtension DLL. First, the DLL is searched in <proj_path>/bin. If it does not exist there, it will be searched in the <wincc_oa_path>/bin. This entry can only be set in the [ui] or the [ctrl] section. If a DLL should be used by the UI and CTRL, this must be loaded in both sections. The number of DLLs to be load is not limited.

Note: It is recommended to load a CtrlExtention DLL directly from the Ctrl script using the #uses statement.

[ctrl] minWorkInterval

Type
int
Default
1
Range
>= 0
Minimal time in seconds the CTRL Manger waits between two work() calls.

[ctrl] queryRDBdirect

Type
bool
Default
0
Range
0|1
Indicates the mode of database read queries:
  • 0 = Standard CTRL read functions (dpGet...()) via the WinCC OA Event Manager and the WinCC OA Data Manager.
  • 1 = The standard CTRL read functions (dpGet...()) are redirected to directly contact the database server.

Note that the two required CTRL extensions must also be loaded in order to be able to use the RDB read functions.

Can be used in [ui] and [ctrl] sections.

CtrlDLL = "CtrlRDBArchive"
CtrlDLL = "CtrlRDBCompr"

CAUTION: If you use queryRDBdirect = 1 and query DPEs using the event screen, enter the DPEs or *.* for the query. Otherwise the event screen does not show the DPEs.
