7.2.2 Connection via the AMO module
Connections fibre-optical interface, Rx and Tx, 820 nm, BFOC/2.5
Protocol semi-duplex
Max. line length
•
2000 m / 1.25 miles for glass fibre 62.5/125 µm

For exclusive utilisation of
AME
modules at the bus.
This value could be smaller depending on the used Modbus master and further modules at the bus.
If more then 32 devices at the bus are needed, RS485 repeaters which support bit retiming have to be used.
