This function adds a new SCRIPT task definition during runtime. If this function is invoked with the same source item ID and module ID multiple times, multiple tasks will be invoked when the source item is changed. The execution of the tasks is in reverse order (the last added as first – the first added as last).
For example:
| Code Block |
|---|
nxa.AddScriptTask("NETx\\VAR\\Numeric\\Item001", "NETx\\VAR\\Numeric\\Item002", true, true, true, 0, "nxa.LogInfo(\"1\")", 1001)
nxa.AddScriptTask("NETx\\VAR\\Numeric\\Item001", "NETx\\VAR\\Numeric\\Item002", true, true, true, 0, "nxa.LogInfo(\"2\")", 1001)
nxa.AddScriptTask("NETx\\VAR\\Numeric\\Item001", "NETx\\VAR\\Numeric\\Item002", true, true, true, 0, "nxa.LogInfo(\"3\")", 1001) |
If item NETx\VAR\Numeric\Item001 is changed, the following system log entries will appear:
| Code Block |
|---|
3
2
1 |
The following code will delete all 3 tasks:
| Code Block |
|---|
nxa.RemoveScriptTask("NETx\\VAR\\Numeric\\Item001", 1001) |
