Uint32 - Quick Client shows values but Tag browser does not

Ignition Early Access
1

Version: 8.0.2-rc1 (b2019052016)

Quick client shows good data. The Tag browser shows bad data of the tags created from the same OPC server that shows good data in the browser quick client.

What am I doing wrong?

Quick Client:
Read completed. [MyOPCDevice]ns=4;i=106
Status: Good
Value: [1]
Quality: Good
Timestamp: 7/24/19, 11:04:30 AM EDT

Read completed. [MyOPCDevice]ns=4;i=103
Status: Good
Value: [2019, 7, 22, 11, 1, 40]
Quality: Good
Timestamp: 7/24/19, 11:07:04 AM EDT

Designer - Tag browser - OPC Server:
“tags”: [
{
“valueSource”: “opc”,
“opcItemPath”: “ns\u003d4;i\u003d103”,
“dataType”: “Int8”,
“name”: “Alarm_Date_Time”,
“tagType”: “AtomicTag”,
“opcServer”: “MyOPCDevice”
},
{
“valueSource”: “opc”,
“opcItemPath”: “ns\u003d4;i\u003d106”,
“dataType”: “Int8”,
“name”: “ComPort”,
“tagType”: “AtomicTag”,
“opcServer”: “MyOPCDevice”
}
]

In the tag browser I have dragged the OPC tree from OPC browser to the Tags folder.

Screen shows type Long with with a value of Red Circled Exclamation Point ‘!’ Bad_Stale

It might be worth getting onto at least the 8.0.2 release version, if not 8.0.3-rc.

What device are you connected to? Do you happen to know if it’s a nano profile device or something like that?

It is a nano server type device. We can read/write to object attributes values and execute call methods with freeopcua(GitHub - FreeOpcUa/opcua-client-gui: OPC-UA GUI Client ), and many other commercial clients. We REALLY want to find a way to use this with Ignition. :slight_smile:

If it doesn’t support subscriptions (common for nano profile) then all you need to do is make a new Tag Group that is in OPC Read Mode and make sure all the tags that belong to this device are in that group.
