ETSNZ Discovering more than 9 devices over two FDM128's

You will be able to view and discover devices over two FDM128's if the devices have a firmware version of 6.4.2. 
If using a FDM128 with a firmware version of 6.3.4 it would be adviseable to upgrade to the latest version. 
If this is not possible it can be done by discovering the devices in two stages.
Disconnect approximately half of the devices from the ULP/Modbus line and discover on one FDM.
Stage 2:
Disconnect these devices and reconnect remaining devices and discover these on the second device. 
Reconnect all devices and all devices will be viewable across the two FDM128 displays.
