Re: Data logger and scheduler

At first localize the problem.
What goes wrong, recording data into database table, reading data from the database or recording into into external drive?
If You reduce period of data logging from 1 to 60 sec what happens?
Do You use the original database or created Your own?

Re: Data logger and scheduler

Check the "Max Number of Logged Rows" in the Data Logger's property.
If number of record made is bigger, the oldest record will be deleted and replaced with the current data.
The default value is 500. If bigger value inserted, an appropriate warning appeared after compilation.

Re: Adding a new table in the general Database.db using scri

Probably, yes. I will google it.
You can add a table to the Database.db with Data Logger.
And You can add an external SQLite database to USB or SD card.
The database errors are not being noticed by iX Developer. Use: try, catch (SQLiteException ).

Re: Debug Tools

Thank You Russ C. for the answer.
I read the reference manual. Not much information is there about debugging. I have Visual Studio 2013 installed. An extra manual (probably, from a third party) would be helpful to learn this option.

Debug Tools

Dear colleagues,
Who used Debug tool in iX-Developer, a nice picture of a ladybird in the "Project" page next to "Simulate" button?
How can it be used? Is it effective and useful? Where to find a proper manual?

Re: How to insert values to the "Time" column of Data Logger

I found solution. After backing up the internal database to USB memory, it was opened with SQLite Expert and the field "Time" type was changed from datetime to nvarchar.
But, how to insert data to fields with SQL type "datetime" is not yet clear.

How to insert values to the "Time" column of Data Logger

My task is to move a Data Logger from internal HMI memory (X2Pro) to USB or SD. I made backup of existing database on USB and wrote a script to make records. It works, but there is a problem with the field "Time". It has format DateTime.
How to insert a value into this column?

Re: Getting IP address from system

Thank You Adam for the link, it is very interesting information. Original task was to check, if the HMI configured as OPC server or client. But, it is not clear, how to check by script, if a controller (OPC client) active or not. Anyway, the problem is solved, because we know now what IP address is ...
