I have an issue whereby I am getting a "Timed Out" message after about 10-12 hours of readings (taken every 30 sec). It happens regardless of the controller that I am reading from. When I redeploy, it works fine again (like it is waiting to be "manually" restarted). **My solution would be to put an Inject node that runs whenever a Timed Out message is detected** , **but where can I put an Inject Node if there are no wire connections on the Modbus Serial In node?** See my flow below which shows the message I get on one of the controllers (again, it happens on the other one, but it not depicted here).
