Create new folder in OPC UA Server #249

Closed NicolaiWrt closed 3 years ago

NicolaiWrt commented 3 years ago

Hello Mika,

I have problems with the setFolder-Command. I created two more Objects under Equipment, there should be also some new variables. Therefore I send a setFolder-Command to the Server Node, but the next variable is also written in VendorName. OPCUATree grafik

How can I create the new Variable under my new objects? (Megomat 1 and 2) Here my Code: [{"id":"5aede970.315ee","type":"tab","label":"Flow 1","disabled":false,"info":""},{"id":"99b874a5.e4e818","type":"OpcUa-Server","z":"5aede970.315ee","port":"53880","name":"","endpoint":"UA/SimpleNodeRedServer","autoAcceptUnknownCertificate":true,"registerToDiscovery":false,"maxNodesPerBrowse":0,"maxNodesPerHistoryReadData":0,"maxNodesPerHistoryReadEvents":0,"maxNodesPerHistoryUpdateData":0,"maxNodesPerRead":0,"maxNodesPerWrite":0,"maxNodesPerMethodCall":0,"maxNodesPerRegisterNodes":0,"maxNodesPerNodeManagement":0,"maxMonitoredItemsPerCall":0,"maxNodesPerHistoryUpdateEvents":0,"maxNodesPerTranslateBrowsePathsToNodeIds":0,"x":300,"y":420,"wires":[["4a6897b1.d2d7a8"]]},{"id":"feb0639e.10e988","type":"inject","z":"5aede970.315ee","name":"{ \"opcuaCommand\": \"addEquipment\", \"nodeName\": \"Megomat 1\" }","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"{ \"opcuaCommand\": \"addEquipment\", \"nodeName\": \"Megomat\" }","payloadType":"json","x":320,"y":40,"wires":[["99b874a5.e4e818"]]},{"id":"4a6897b1.d2d7a8","type":"debug","z":"5aede970.315ee","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":470,"y":420,"wires":[]},{"id":"e4eba1d0.42dc98","type":"inject","z":"5aede970.315ee","name":"{ \"opcuaCommand\": \"setFolder\" } \"Megomat 1\"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"\"ns=1;s=Megomat1\"","payload":"{ \"opcuaCommand\": \"setFolder\" }","payloadType":"json","x":260,"y":160,"wires":[["99b874a5.e4e818"]]},{"id":"d546a956.fddca8","type":"inject","z":"5aede970.315ee","name":"{ \"opcuaCommand\": \"addEquipment\", \"nodeName\": \"Megomat 2\" }","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"{ \"opcuaCommand\": \"addEquipment\", \"nodeName\": \"Megomat\" }","payloadType":"json","x":320,"y":80,"wires":[["99b874a5.e4e818"]]},{"id":"60eb41fc.5cb61","type":"inject","z":"5aede970.315ee","name":"{ \"opcuaCommand\": \"addVariable\" } ns=1;s=Test\";datatype=Int32","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"ns=1;s=Test\";datatype=Int32","payload":"{ \"opcuaCommand\": \"addVariable\" }","payloadType":"json","x":310,"y":120,"wires":[["99b874a5.e4e818"]]},{"id":"6d6fb9ae.36f908","type":"inject","z":"5aede970.315ee","name":"{ \"opcuaCommand\": \"addVariable\" } ns=1;s=Test_Value\";datatype=Int32","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"ns=1;s=Test_Value\";datatype=Int32","payload":"{ \"opcuaCommand\": \"addVariable\" }","payloadType":"json","x":330,"y":200,"wires":[["99b874a5.e4e818"]]}]

Hey Mika,

thanks for your fast answer. I try to import your code, but NodeRed gives me an error. grafik I use NodeRed on Windows 10.

Another thing: Do you have a manuall for writing data to the server?

Thanks in advance. Best regards

Nicolai

Copy & paste have removed something. Rename SERVER.txt SERVER.json

SERVER.txt

Writing depends on your nodeId & type, you can use UaExpert or client node with node-red.

mikakaraila commented 3 years ago

Just a final screenshot: change value with UaExpert and subscription will show value on node-red:

Hi everyone,

if you wanted to create a tree structure with folders like :

Folder 1: subfolder1_child_1 subfolder1_child_2

Folder 2: subfolder2_child_1 subfolder2_child_2

how should I do?

mikakaraila commented 1 year ago

Trial & error or use addFolder / setFolder by default addFolder will set new folder as parent folder.

Look example from OPCUA-TEST-NODES.json
