2018-09-21 02:54:40 Error compiling the source code of the formulas:

Hi,
This message means that there is a problem in a formula of input channel. You should fix the formula and restart the Server service.
See line 571 in C:\SCADA\ScadaServer\Log\CalcEngine.cs to find out what is the formula is incorrect.

Users of the Guest role can view all. If you don’t want it, create your own custom role and apply it to the user named “guest”.

[Mikhail]

Hi,

You should research what the services do when they not respond.
Check logs of Server and Webstation.

Hi Josef,

Other approach that may be easy to understand:
1. Install Automatic Control Module and create triggers that will raise commands on your conditions. There are delays and deadbands available.

2. Create an output channel and use SetVal() function to change a corresponding input channel.

1. Try to delete WebSettings.xml.bak manually.

If it doesn’t help:
2. You should open properties of the C:\SCADA\ScadaWeb\config\ folder and allow read/write access to a user that is written in C:\SCADA\ScadaWeb\log\ScadaWeb.log
I often provide access for all users, but this is not secure.
Apply changes recursively.

Hi,

Have you tried the above advice?
What is written in C:\SCADA\ScadaServer\Log\ScadaServerSvc.log ?

[Mikhail]

This is not necessary to add admin and guest to the Rights table. These roles are standard.

The screenshots are clear. I didn’t catch what goes wrong? ))

[Mikhail]

Writing issue: use Matrikon OPC to compare. If it works, the cause is related to the particular OPC.

[Mikhail]

I need to restart the computer to use again the server

Try restarting Communicator service.

1. Please open Administrator, open the Channel types table and find the descriptions.

2. What is the context?
In most cases, tag means variable in SCADA.

3. Yes

Try unblocking PlgSchExtraComp.dll
Example

[Mikhail]

Hi Phachakorn,

Does ‘C:\SCADA\ScadaWeb\bin\PlgSchExtraComp.dll’ file exist?
What is the installation directory of Rapid SCADA? I suppose C:\SCADA\

Note: Because your company purchased Extended support subscription, you also can solve issues by email or ticket tracker which is faster than forum. It’s up to you.

> Tag value has been passed to OPC server. Name: PLC1.Generic.sensor-nivel-bajo-tanque-principal

The above line says that the command is sent.
What OPC server do you use?
Can you try sending commands to Matrikon OPC for testing reason?
What communication protocol is used by the PLC?

[Mikhail]

Hi,

Could you provide screenshots of the settings and of the web app?
