50.51 FBA B timelevel sel Selects the communication time levels.
In general, lower time levels of read/write services reduce
CPU load. The table below shows the time levels of the
read/write services for cyclic high and cyclic low data with
each parameter setting.
* Cyclic high data consists of fieldbus Status word, Act1
and Act2.
** Cyclic low data consists of the parameter data mapped
to parameter groups
55 FBA B data in and 56 FBA B data
out , and acyclic data.
Control word, Ref1 and Ref2 are handled as interrupts
generated on receipt of cyclic high messages.
