The happening frequency seems pretty random.

On my test yesterday, it happened a few times per hour. but when I try to repeat this today with the same pc and the same project, it doesn’t happen at all.

[JW]

Just check the scadacomm log of other projects, all project with similar settings.

most project detects a communication line disconnection every few days.
I disabled detailed log, so it only show disconnection but not the cause.
I believe they may have the same cause.

Hi, It’s fixed on my test.

[JW]

It’s fixed on version 5.8.2. Have a try.

[JW]

this bug is fixed by above update.

[JW]

Hi,

I found the difference.

Selecting “Input channels” the whole table then find and replace will not experience crash.

But selecting sub tables such as “[11]ADAM-6015 Server room” then find and replace will experience crash.

[JW]

yes, that’s the same actions I did.

I am going to try on another computer tomorrow and see what’s the result.

[JW]

Hi Mikhail,

I Found a way to reproduce this consistently using the DemoProject.en-GB.
1. goto input channel table [11]
2. find and replace
Column: Name
Find: t
Replace with: s_t
uncheck match whole cell.
3. the 1st time will be performed correctly
4. do the same find and replace again, Administrator app will crash.

[JW]

Sometimes when you change settings in role table or interface table, you will need to restart the IIS service for Windows or apache2 service for Linux to make it effective, instead of just restarting the scada server.

[JW]

Hi, I tried the auto login module with rapid scada 5.8.1 on both windows and linux. Neither of them work.

When try to use auto login URL, the web show only the following error message.

Application Error
An application error occurred. If it repeats often, please contact the support.
Details:
c:\SCADA\ScadaWeb\Login.aspx(19): error CS0103: The name ‘phrases’ does not exist in the current context

**note: the files in the link above are the configs that will trigger the issue, not the workaround.

[JW]

The picture you post is not visible.

Below are my experience and tips of sending command to external modbus device. Not sure is it the same issue you encountered.

When 1 trigger triggers and sends 2 commands to 1 same external device. the auto control module stops working will work at the beginning, but fail after a few events.

Then I set some delay to each command, then it seems ok as a work around.

my device comm setting, auto control setting and server log are attached in the following link.

never mind, just found it here…

I mean no matter what scale the user choose previously, e.g. fit to width, 50%zoom, or 100%zoom before he close the web, next time he opens scheme view again, it will be “fit to screen”. is it possible?

[JW]

The scale setting can be remember by browser, which is a nice solution.

However, sometimes I wanted to force the browser use “fit to screen” every time the user open a scheme view, is there a way to do it?

Because I usually use a very high-res map/cad drawings (e.g.6000×4000) as background image to allow user to zoom-in to see details. if it’s not “fit to screen” at the beginning, some user lost track of where they are looking at.
