9.3.4 Glitch-Free Power Up and Power Down

Communication on the bus that already exist between a master node and slave node in an RS485 network must not be disturbed when a new node is swapped in or out of the network. No glitches on the bus occur when the device is:

  • Hot plugged into the network in an unpowered state
  • Hot plugged into the network in a powered state and disabled state
  • Powered up or powered down in a disabled state when already connected to the bus

The ISO1500 device does not cause any false data toggling on the bus when powered up or powered down in a disabled state with supply ramp rates from 100 µs to 10 ms.
