Unfortunately we do not have such a server available in the lab. Could you please add a few code lines and give it a try.

Add in Line 44 after PublishHelper.Execute(…):
var TotalNumberOfDataChanges = PublishHelper.CurrentDataChanges[0].MonitoredItems.length;
while (PublishHelper.Response.MoreNotifications == true) {
PublishHelper.Execute();
TotalNumberOfDataChanges += PublishHelper.CurrentDataChanges[0].MonitoredItems.length;
}
…

Line 53:
Change "PublishHelper.CurrentDataChanges[0].MonitoredItems.length" to "TotalNumberOfDataChanges"

…

Same needs to be done in Line 141:
TotalNumberOfDataChanges = PublishHelper.CurrentDataChanges[0].MonitoredItems.length;
while (PublishHelper.Response.MoreNotifications == true) {
PublishHelper.Execute();
TotalNumberOfDataChanges += PublishHelper.CurrentDataChanges[0].MonitoredItems.length;
}
…
And in Line 147 change "PublishHelper.CurrentDataChanges[0].MonitoredItems.length" to "TotalNumberOfDataChanges"

Please do let me know if this worked out well as I can't test the scripts without a server.

I made the modifications to test "Monitored Item Services - Monitor Basic - 18". The test now got some other errors.
On line 132 in 018.js 10 items are written. 5 are ok but 5 gets the following errors:

• Invalid data-type '0' (Null). Value is unchanged.
• Write().Response.Results[X] is not good: BadTypeMismatch (0x80740000)

Let me know if I should make any other modifications.

The message about the DataType being Null should only happen, when the Value Attribute of the UaNode is set to NULL.
Could you try to initialize the values in the server with an apropriate value set and see if you're still having troubles?

Apply the fix
