WCCILevent (0), 2020.06.17 10:27:46.908, PARAM,SEVERE, 92, DP functions: infinite loop found, DP: System1:Pump1.status.counter:_dp_fct, EvDpManager::, handleDpFuncHL #1, check dp function


Log-message with symbolic names:

WCCILevent (0), <TIMESTAMP>, PARAM,SEVERE, 92, DP functions: infinite loop found, DP: <DP-Name>:_dp_fct, EvDpManager::, handleDpFuncHL #1, check dp function


This log-message can have 2 reasons:
1) An infinite loop is configured, e.g. dp-function at datapoint-element A reacts on changes at datapoint-element B, at dp-element B a dp-function is configured which refers to dp-element A.

2) The dp-function was called with the same time-stamp at the input-variables more than 25 times.
In this case please check the configuration of the dp-elements which are used as input-variables.
