50.12
FBA CYCLE TIME
(see above)
Selects the fieldbus communication speed. The default selection is
. Lowering the speed
reduces the CPU load.
The table below shows the read/write intervals for cyclic and cyclic low data with each parameter
setting.
*Cyclic data consists of fieldbus CW and SW, Ref1 and Ref2, and Act1 and Act2.
**Cyclic low data consists of the parameter data mapped to parameter groups
(0)
