Tags are addressed to look at reports brcbA02 and urcbA02. Both reports are open and are not being utilized by another device.
All tags connected to the reports are displaying: "Uncertain_InitialValue("The value is an initial value for a variable that normally receives its value from another variable.")"
Good morning sir. I have the same problem right now. I added a new IEC61850 device to my ignition gateway and try to verify the connection with the OPC quick client but it keep appearing the message "Uncertain_InitialValue("The value is an initial value for a variable that normally receives its value from another variable.")" when I try to read a variable inside a report.
I found that when I chose to use REPORT1, even though I confirmed my packets using Wireshark, no data appeared. However, when I chose REPORT6, the data could be received normally.
I have also raised some questions about 61850. You can refer to this post:
