Control IEC61850 function block

[gunhunter]

Hi sir
 I want to control SPC variable within zenon logic. I will use IEC61850_WRITE function. it explain that 

 
PATH 

         STRING

                        Path to data point (without "ServerName!")

 IF I set path = Bay431!BAY431System/PloGGIO1/SPCSO1/Oper.ctlVal[CO], your program said "main: (11,36): PloGGIO1: Unknown identifier "
so what can I do to resolve problem
Thank you

Hi sir 
if I use Inst_IEC61850_OPER1 ( TRUE, 5 , {Bay431!BAY431System/PloGGIO1/SPCSO1/Oper.ctlVal[CO]}, 1 , 1 );
with SERID =5, CHeck =1 (direct with normal security), value =true
is that true?
thank

Hi sir
Sorry, I need some infomations about my request "Inst_IEC61850_OPER1 ( TRUE, 5 , {Bay431!BAY431System/PloGGIO1/SPCSO1/Oper.ctlVal[CO]}, 1 , 1 );" to relay Not working
I config that SERID =5, CHeck =1 (direct with normal security), value =true? but Relay is not change value.
So what must I do to resolve that problem?
Thankyou

you are confusing the parameters of function block IEC61850_OPER. This FB is documented in Help:
IEC 61131-3 Programming Environment -> Fieldbus configuration -> IEC 61850 Client

In IEC61850_OPER:
- the input PATH is a STRING, not a variable reference. Thus, in your case would be probably 'BAY431System/PloGGIO1/SPCSO1/Oper.ctlVal[CO]' (and not "{Bay431!BAY431System/PloGGIO1/SPCSO1/Oper.ctlVal[CO]}"). Note: string expressions are delimited with ' char.
- the input CHECK has nothing to do with the Control Model. Using CHECK input you can define an additional parameter in the command informing the 850-sever if the command shall be performed with some interlocking checks. The list of possible Oper.Check are defined in the Standard: 0 - no check, 1 - interlock-check, 2- synchro-check, 3 - both checks.

The Control Model defines if commands are Direct or with Select, in normal or enhanced security. Using operate command you cannot force some Control Model like you (850-client) want. While giving the command the 850-client has no influence on the Control Model, as this is already defined in the 850-server (the server knows it and client has to perform like the server it has).
If you need to change the Control Model of the 850-server (assuming this 850-server allows it) you would have to write it before you send the commands.

additional tipp:
the function block IEC61850_OPER works in all Control Models automatically. When you use this FB then the IEC61850 Client driver first reads from 850-server what is the current Control Model and then executes the command accordingly. So, if current Control Model is not 1 ('direct, normal security') but 2 or 4 ('Select Before Operate ...') the driver will first send a suitable Select or SelectWithValue request and only by positive response from 850-server - as next the Operate request. And if Control Model is 0 ('no control possible') the driver will not send the command.

When you see that the relay is not executing the commands you sent from logic - check the outputs STATUS and RESULT of the function block.
