ssc_addKPINodes()

The function adds a plant model node of the type CNS_NODETYPE_KPI and links it to the KPI instance.

Synopsis

void ssc_addKPINodes(string node, string kpiName, string kpiDPName);

Parameters


Parameters	Description
node	A plant model node to which the KPI node is added.
kpiName	KPI name is used to generate a CNS node name.
kpiDpName	The KPI instance DP to be linked to the node.

Return Value

Description

The function adds a plant model node of the type CNS_NODETYPE_KPI and links it to a KPI instance. KPI instances are created for KPI definitions.

Example

The function adds a plant model node "Drive3" of the type CNS_NODETYPE_KPI to the plant model and links it to a KPI instance "kpi__Electric_Power0". The plant model node "Drive3" is added to the structure node "Hall1" (see figure further below). The KPI definition "Electric_Power" was created via the function ssc_defineKPI(). The instance "kpi__Electric_Power0" is an instance of the KPI definition "Electric_Power".

main()
{
  string node= "System1.Plant:Hall1";
  string kpiName = "Drive3";
  string kpiDPName = "kpi__Electric_Power0";
  ssc_addKPINodes(node,kpiName,kpiDPName);
  if(""==kpiName)
  {
    DebugN("Enter a name for the node");
  }
  dyn_errClass errors = getLastError();
  if(dynlen(errors)>0)
  {
    DebugN(errors);
  }
  else
  DebugN("Node:",kpiName, "was added and linked to the KPI instance DP
  ", kpiDPName);
}
