Hi! The reserved word 'return' is not accepted when call the method, and this aborted.

##Server
t.add_method :MethodX,
            inputarg1: OPCUA::TYPES::INT32 do |node, inputarg1|
            p "Argument: #{inputarg1}"
            return inputarg1 + 1
end

##Client
p node.call 1

What I do wrong? tnks

I have defined the following code

at = server.types.add_object_type(:ActualType).tap{ |t|
    t.add_variable :JointPositions
    t.add_variable :JointVelocities
    t.add_variable :JointCurrents
  }

  rt = server.types.add_object_type(:RobotType).tap{ |r|
    r.add_object :Actual, at, OPCUA::MANDATORY

When i connect to the server with UA Expert all nodes of the type were instantiated twice. Once with a numeric random NodeId and once with the string NodeId.

When i manifest the ActualType after instantiation of the RobotType everthing works.

Hi,

I used the following example code for connecting to a OPCUA server:

require 'opcua/client'
client = OPCUA::Client.new("opc.tcp://192.168.1.50:4840")
client.subscription_interval = 100 # default 500

while true do

  if (node = client.get 2, 3)  # get node from nodeid
    #p node
    p node.value
  else
    p 'invalid nodeid'
  end
  
  sleep(2)

end

Somehow you need to set the node ID instead of the string as given in de example.
I run for testing a python opcua server with intergers and strings.
When I use the ID for the string variable the node.value changes to this value but when I use the ID for a interger variable then it gives back 'nil'.

Do you know what I am doing wrong?

Thanks in advance! @etm

support for opc ua arrays

When execute, show this error:
`require_relative': cannot load such file -- /home/user/opcua-smart/lib/opcua/client.so (LoadError)

how fix this error?

When defining two types like:

server.add_namespace "https://centurio.work/ur10"

  tt = server.types.add_object_type(:TargetType).tap{ |t|
    t.add_variable :JointPositions
  }
  #causes errors, because both Jointpositions got the same nodeid
  at = server.types.add_object_type(:ActualType).tap{ |t|
    t.add_variable :JointPositions
  }

i get an error

AddNodes: Node could not add the new node to the nodestore with error code BadNodeIdExists

because both JointPositions nodes got the same Nodeid.

Hi,

I am trying to use this gem on my raspberry Pi 4 with smashing dashboard but when I run "smashing start" I get the following error:

bundler: failed to load command: thin (/usr/local/bin/thin)

My .rb file looks like the following:

#require_relative '../lib/opcua/client'
#require opcua/client

client = OPCUA::Client.new("opc.tcp://192.168.1.50:4840")
client.subscription_interval = 100

if (node = client.get 2, 'Pressure')
p node
p node.value
else
p 'invalid nodeid'
end

When I run "ldconfig -p | grep libopen6" I get this:
libopen62541.so.1 (libc6,hard-float) => /usr/local/lib/libopen62541.so.1
libopen62541.so (libc6,hard-float) => /usr/local/lib/libopen62541.so

Hoppefully you can help me.

Thanks in advance!!

Hello,
I'm trying to use the gem, I have compiled and installed the open62541 library in my environment.
When I try to install the gem got:

_Installing opcua 0.21 with native extensions

I saw that the file not found is not in the include dir, but after manually adding it from the project legacy folder I've got the same error.

What am I doing wrong?

Thanks

Nicolò :)

Provide method for deleting nodes in address space. This is required for dynamic construction of the address space.
