Modbus TCP hangs if one device is not reachable

Configuration
1

Hello,

sometimes, one of my modbus tcp devices loses network connectivity.
At this time, all of my sensors for other devices which are configured through modbus tcp are also not working. It seams that modbus completly get stucked.
Is this correct, or do i have a missed something in my configuration?

here are two modbus devices from my configuration.

modbus:
  - name: "Pluggit"
