Response and Listerner limited to 1000 variables #87

Closed thecalle closed 4 years ago

thecalle commented 5 years ago

I'm submitting an unexpected behaviour.

Current behaviour: IIoT OPC UA Browse2Listener example scenario. Connect to OPC-UA server exposing 4000 variables, Response gives 1000 variables, Listener subscribes to 1000 variables.

Expected behaviour: Connect to server exposing 4000 variables, Response gives 4000 variables, Listener subscribes to 4000 variables.

Environment: I am using just the Node-RED package and got node-opcua installed with it.

Device : Raspbian: GNU/Linux 9

thecalle commented 5 years ago

Browsing also (using magnifing button) is limited to 1000!

biancode commented 5 years ago

Hi, check your server settings! We use 10k nodes in other projects.

thecalle commented 5 years ago

Hi Klaus. I connect to the same server using UaExpert Windows client and I get about 4K varibles under Tags. Node-red browser stops exactly at 999.

v3.8.0 of the package? Please, Francesco, could you take a screenshot of the sever limits from UAExpert and push it here or send it by E-Mail!

thecalle commented 5 years ago

Hi Klaus.

I checked the parameter you suggested. The MaxNodesPerBrowse is set to

All the parameters in Operation Limits are set to the same value.

Francesco.

anthrogan commented 5 years ago

I have experienced similar with only returning 1000 tags, and ultimately bringing the opc server down (WinCC... Again! I can't confirm max nodes per browse either with wincc as the server does not expose this)

biancode commented 5 years ago

How can I reproduce this use case?

biancode commented 5 years ago

browse is restricted now from node-opcua and it will provide the browse next in a next step end of the month march 2019

erossignon commented 5 years ago

@biancode browse will limit the number of returned node to 1000 and will set a continuous point in the response if more than 1000 nodes exists. To get all the node , one shall call browseNext repeatedaly until continous point becomes null.

biancode commented 5 years ago

@erossignon you said it is not possible to call browseNext for now last time. Is it possible now and from which version of node-opcua, please?

erossignon commented 5 years ago

on the client side, OPCUACLient#browseNext can be used since a long time and shall be available in v0.7.0. version 2.0.0 will add further enhancements and browseNext support in the server and in the client crawler.

biancode commented 4 years ago

browseNext works

biancode commented 4 years ago

6kNodesFlowBrowse.json.zip

needs v3.11.3 or above

biancode commented 4 years ago

fixed with v3.12.0 - but the listener itself is also limited by the server how many items to be monitored at the same server
