Infinite loop in dp_fct

[nedzad]

Hello,

I'm having the following log-message in PVSS_II.log-file:

SysSarani:OA-OS2.A13.cmd.bit.b3:_dp_fct, EvDpManager::, handleDpFuncHL #1, check dp function

On this link I found the explanation for this message, but it seems that neither of those two mentioned reasons is causing the infinite loop in my case.

As I can see, all datapoint elements that refer to the same datapoint element in their dp functions are reporting this error, e.g. when dp-function at datapoint-element A reacts on changes at datapoint-element C, and dp-function at datapoint-element B also reacts on changes at datapoint-element C, both the dp-element A and dp-element B are reporting infinite loop.

Any help would be appreciated.

Best regards
Nedžad

Hello,

in the part of the log message you have copied to the posting I cannot see the information for an "infinite loop".
Can you please copy the complete content of the log message.

Sorry, here it is:

WCCILevent (0), 2017.05.04 11:05:35.889, PARAM,SEVERE, 92, DP functions: infinite loop found, DP: SysSarani:OA-OS2.A13.cmd.bit.b3:_dp_fct, EvDpManager::, handleDpFuncHL #1, check dp function

Most of the time the dp function is called several times with values with the same time stamp leading to the log message.
Did you check the value + timestamp for the dp elements which are triggering the dp function?

E.g. this can be done with a CTRL script doing a dpConnect for _online.._value and _online.._stime.
