How change the state of variable in AddIn Runtime service

[tsvoboda]

Hello ursulak and markclemens, 

thank you both, for your replies they were very helpful. At least i realized that set SPONT makes no sence and new options how to do it.
I would like to run the option in AddIn framework. 

But still struggle with to set state for no-internal variables. 

I tried many solutions i code like: 
variable.SetValue(variable.GetValue(0), newStatusInt, DateTime.Now.Minute, (Int16)DateTime.Now.Millisecond); -> This works me for internal variables
variable.StateString = "REVISION," + variable.StateString;
variable.StateString = "REVISION";
variable.StateString = "REV = 1"; -> accorgind https://forum.copadata.com/showthread.php?2884-Switch-limit-active-inactive-in-Realtime
variable.StateString = "REVISION = 1"; 

varialble.lowerState = newStatusInt; -> // Error: lowerState just get property
variable.set_StateValue(newStatusInt);  // Not suported in AddIns

Log results: 


Do you have any idea where could be problem?
Big thanks for your time. 

Best regards.

Hi,
I did this in an older project with VBA, not sure wether this works the same way as in AddIn, but did you try
variable.StatusString = "REVISION=1" //Remark: no blanks! same with REVISION=0
in AddIn it's probably .StateString

Hi everyone who participated on this problem,

thank you all for your replies and at this time we can mark this thread as [SOLVED]. 

This is result: 
Only way how to change a state of variable in AddIn is by use this method: 
variable.SetValue(variable.GetValue(0), newStatusInt, DateTime.Now.Minute, (Int16)DateTime.Now.Millisecond);

It works me too almost whole time, but i didnt notice it. I expected that the result would be seen immediately on next row of code, because 
the return value of method is Void, so we cant wait on result.
The set of state can be expected on next row in code just for Internal variables, but for others you should count with some time spacing. 

Once again thank you for help everyone. 
Best regards.

right. Thank you, now I understand your difficulties.

Just to complete explanation: the Internal driver is a pure memory access, the write to memory is then immediately the result in the variable; value of variable = memory content. The Internal driver is not an independent application (no separated exe), it is integrated in the Runtime. Other drivers are not "pure" memory access and they are separated applications. There is special routine for information exchange between zenon Runtime and driver: when RT writes (pokes) a value/status bit to the driver the variable in RT has still the previous value and status bits and only driver knows as well old as new. Then driver sends back to the RT the update of the variable. If driver didn't need to send this value to PLC (e.g. it is only update of status bit like REVISION), and the RT - drivers data exchange has low traffic, then I would expect the delay <=100ms.

The update of a variable is an event, so for check of result (if needed) - catch the events.

Hello, 

thank you Mr.ursulak for extra explanation. Now everything is clear to me. 

I found one extra problem. According the reply: 

Please activate the setting "Status/Timestamp for Variables of internal Driver" in the general project settings in the section "runtime settings".

This check box "Status/Timestamp for variables of internal Driver" is just in zenon 8.0 right? I did not find it in zenon 7.60. Is here some other solution in zenon 7.60? 

Best regards and thx for you time.

This check box is only available in zenon >= 8.00 and has an effect on the availability of status and timestamp information of the internal driver. It is a result of the changed licensing rules, that apply to zenon since version 8.00

For 7.60 this is not relevant for you.

In zenon 7.60 it is controlled without check-box, but only by project.INI entry. The ini file you can find when in zenon Editor you click on project name -> Ctrl+Alt+E -> \zenon\system\project.ini
...
[RT]
INTERNALDRIVERWITHSTATUS=1
…

value 1 there activates timestamps and status for internal variables (and counts then to license), value 0 - no timestamps, status; and the internal tags are "for free".

Thank you, for quite useful reply, but in 7.60 the attribute "INTERNALDRIVERWITHSTATUS" is not. 
There are just these: 

[RT]

DRIVER_HIDE=1

MULTITOUCH=0

TOUCHSCREEN=0

KEYBOARD_PERCENT=100

WITH_ACTION=1

LOCKED_KEYS=1

When i tried to add the attribute, it was removed by compilation of the project again. Please do you have other idea? 

Thank you for your cooperation 

[ursulak]

In zenon there are 2 project.ini files - is as well in Editor, as in Runtime, directories. The file from Editor directory overwrites the file in Runtime directory by each project compilation. So please update the ini file in Editor (Ctrl+Alt+E), not in the Runtime directory (Ctrl+Alt+R).

Hello COPA-DATA,

thank you very much for your help. Defining that parameter in project.ini has helped us, but

we got another problem. The problem is still related to the problem of changing the state of a variable using the method:

// 4. SWITCHING STATE

variable.SetValue(variable.GetValue(0), newStatusInt, DateTime.Now.Minute, (Int16)DateTime.Now.Millisecond);

Current status:
- it works for internal variables after checking “State / Timestamp for Intern Driver variables” option or after added the parameter to editor project.ini
- it also works for external variables, but only in simulation mode



- but it does not work for external variables with a real connection already

Right now I have no idea where the problem may be. If it is not necessary to take any action to confirm the writing of a new value via Driver or something similar. Please do you have any idea what the problem might be? Please, if you would like more information to help you to solve the problem, don't hesitate to tell me.

Best regards
