Dear Team,
I am trying to write a BIT having variable tree of "@Branch01.Bit02" with IEC 61850 ICD file provided by a Customer.
With IED SCOUT, this tag is able to change 0 or 1 successfully.
But with PcVue, I am facing the below error in Event Viewer.
2023/07/27,16:26:42.313,5,I,,1,,1,IEC61850,ERROR,'Network01/LINE1_BCU','Branch01.Bit02','LINE1_BCULD_ASHIDA/RLGGIO7$CO$SPCSO4$Oper$ctlVal',Data write response: Object-access-denied
[The PcVue version am using is 16.0.2]

Hi Mansoor,
In such cases, the best way is to compare with Wireshark pcvue and iedscout. Check the frames when working and when not working.
By the way, according to the error message, I guess you can't force directly the attribute. Did you map the PcVue variable to the Object or to the attribute?

Hi Nico,
You are right, I have map on attribute.
But When I try map on Object, it is not browsing the CDC, even I tried entering SPC manually, the communication not working with Object mapping.

So I guess you must solve this point first
--> Wireshark is our friend!

Dear Nico,
After selecting Data Object and Member path as "LINE1_BCULD_ASHIDA/RLGGIO2$CO$SPCSO1" (It shall not to be till leaf), it automatically taken SPC as CommonDataClass.
My mistake was I have assigned something like this till leaf, "LINE1_BCULD_ASHIDA/RLGGIO7$CO$SPCSO3$Oper$origin"
Thankyou Nico 🙂

Hello Mansoor,
I suggest you to read the chapter Linking a variable to an IEC 61850 data object or data attribute>How to map a variable for control. It explains the way to configure a 61850 PcVue variable.
You will see that you have to link to the ST functional constraint and not the CO.
Hope it helps.
