VarTrend for Operators

[NikolayLevchenko]

Hi,

We need to allow operators to create their own trends. I am quite happy to use the ETM-standard VT panel as it has everything we need (create new trend, add pens, set up colours, lines, etc.)

There is one major problem I've encountered though.
Judging by the code in the trend panel, I thought I have to give operators permission bit 3 (which I can live with). But as it turns out I have to give operators permission bit 4 (default system permission for dpCreate), otherwise, trend panel can't even create new datapoint for the trend.

I don't feel very comfortable giving operators permission bit 4 as it would allow dp's creation and deletion(!). It seems VERY strange to me that operators have to effectively have Admin access to be able to create trends.

Am I missing something? Is there some other (proper) way of using VT?

Any ideas?

Hi Nikolay,
I have encountered the same problem. My solution was creating specific internal datapoints(for example: _VarTrend_Operator1 to _VarTrend_Operator20) for the Operator Trend with some specific name before the Runtime.
In my panel, when Operator click "create" a Trend, this means some Trend settings are saved in the internal Datapoit(which is already avaliable) and this Operator Trend is visible.

I hope it helps.

I just checked the CTRL code and I have seen that the panel for the VarTrend configuration is creating the datapoints.
To get it fixed in a future version I have forwarded this information to our developers with a suggestion how to solve it.
