Write a variable tag with control client

Nicolas Nehr over 1 year ago

Hi everyone !

Software : Citect SCADA 2015 V7.50

I have recently purchase a control client licence in order to write some DISK variables in a distant server from a client.

So using the computer setup wizard, I have configured the role.

Then in a script, I would like to use the function "TagWrite()" to write the DISK variable.

To use the function TagWrite, you need to be logged in.

But when I try to log (using Login() function), all the communications crashs (the displayed variable becomes #COM state).

Can you help me with this problem ? Thank you all

Does the user that you are login into have a password? I know in version 2020 forward passwords are required for security, so if one logs onto a system without a password, communications are cut off.

Yes the user does have a password. I didn't assigned any roles though.
But I did the exact same thing on a server and it worked fine, the login() function doesn't crash the com (except in this case I'm using a licence server and "Server and Control Client" role in the Computer Setup Wizard).
