Variable not defined (using pmon_query).

[NFedorenko]

Hello to all.

I need to get info about WinCC managers in my project.
I made a little script for a button:

Code: Select all

#uses "pmon"

main(mapping event)
{
  dyn_dyn_string res;
  pmon_query("MGRLIST:LIST", "localhost", 4999, res, true, true);
  DebugN(res);
}

But when I use it I got:
WCCOAui (1), 2019.01.21 11:52:04.059, CTRL, SEVERE, 176, Uncaught exception in thread started at main:
WCCOAui (1), 2019.01.21 11:52:04.058, CTRL, SEVERE, 73, Variable not defined,

2: main(mapping event = ([ 10 items ])) at [Module: _QuickTest_ Panel: dev\ManagerControl.xml Object: PUSH_BUTTON1 Script: Clicked]:6

What should I define, or what's wrong?

If you want to use the (internal) functions defined in pmon.ctl you have to ensure that the requirements for these functions are fulfilled.
As the functions in pmon.ctl are made for WinCC OA internal tasks there is no detailed documentation available.

Which information to you want use in your WinCC OA project?
Which version and patch are you using?

Thanks for your reply!

I need to get status of managers, start and stop them from ctrl-script, add\delete managers from ctrl-script.
Version - 3.15 p015

[leoknipp]

If you want to stop a process (connected to the Event Manager) you can write the manager ID to the dp element _Managers(_2).Exit. The manager ID you can get by using the function convManIdToInt().

There is no need to call a PMon function to stop a manager.
If the startup option "always" is set the PMon will start the manager again.

You can have a look at the script pmonWatchdog.ctl to see how the pmon_query() functions works.
This script can be used to stop a blocking manager, details can be found in ReadmeP013.txt.

Why do you want to add/delete managers during runtime?

Great!
But how can I start manager from ctrl-script?
I want to delete\add managers because of the information security solution.
If I can do that using WinCC OA console manualy, I think it's easy to do the same thing through ctrl script.

[leoknipp]

You can have a look at the CTRL scripts defined in the panel panels/projAdmin/console.pnl to see how a manager status can be modified.

You have to keep in mind that a project can be password protected.
In that case you would have to define the password in plain text in your script if you want to access the Process Monitor. Defining a password in plain text is not the best solution.

The log message show the information that variables are not defined.
If you want to use the (internal) functions defined in pmon.ctl you have to ensure that the requirements for these functions are fulfilled, e.g. all necessary variables are defined.

Did you have a look at the script pmonWatchdog.ctl to see which variables are defined for the pmon functions?

try using pmonWatchdog instead of pmon
