Thank you Hopperpop for contribution, awesome work!
- Better support for nodes that operate at the same time
  - No more errors when all nodes try to connect to the PLC (Already connecting to the target)
  - Other nodes will wait for the result of the connection that the first node is creating
- If first connection to the PLC fails at startup, warning is shown instead of error
Old ads-client-connection is always disconnected (if possible) in handled manner when (re)connecting

[1.2.0] - 30.06.2021

Added

New node Connection Status that reports ADS connection status changes
- Automatically outputs latest connection status when changes detected
- Can also be read manually using input trigger
- Outputs true/false (ok/not ok) and connection info
New node Read Runtime State that implements ads-client library readPlcRuntimeState()
- Possible to read PLC status (run, stop) from Node-RED
New node Read System Manager State that implements ads-client library readSystemManagerState()
- Possible to read system manager status (run, config) from Node-RED
Updated ADS connection node
- Automatically tries to connect to the target PLC in the background
- Before the connection was retried only when reading/writing/subscribing
- Now automatically connects when possible -> supports the new Connection Status node
Updated Subscribe node
- Listens on connection state changes in a better way than before

[1.1.1] - 30.05.2021

Changed

Improved error handling (see pull request #8)
- Thank you Hopperpop for contribution!
Updated README
- Example how to configure and read value

[1.1.0] - 20.05.2021

Added

New node Invoke RPC Method that implements ads-client library invokeRpcMethod()
- Possible to call function block methods from Node-RED
- Thank you Hopperpop for contribution!

Changed

Subscribe node
- If connection is lost, status is updated
- If no notifications received in configured time after reconnection, the node will try resubscribe (new setting Resubscribe timeout [ms])
- ads-client should automatically resubscribe everything, but this is just in case
All nodes now have similar status shapes

[1.0.4] - 18.05.2021

Added

Name properties to all nodes (also connection config -> PLCs can be named)

Changed

Read Symbol and Write Symbol nodes no longer clear the input message. Instead it's passed onwards.
Added better support for error catching (Subscribe is still probably not working 100% with Catch nodes)
Node status messages are now shorter and more compact
