3BSE015969-600 A
Calculation of the ModuleBus delay for the configuration in
:
ModuleBus delay = (total delay in optical fiber) + 5 x (opto-to-opto delay in
TB820/TB820V2) + 2 x (delay in TB825) + (opto-to electrical delay in
TB820/TB820V2) = (4 x 15 + 3 x 1.5 + 1000) x 0.01 + 5 x 4 + 2 x 2.4 + 6.5 = 42 µs.
