6.2.21.3 Task setting and synchronous fieldbus operation
For the influences of the task setting on the fieldbus operation please also read the
manual ma_dr_x6_fbs_phb_20191938_en.
The minimum value for synchronous fieldbus operation is dependent on is22.
The changeover of the basic process time has the following effects on the synchro-
nous PDOs:
i
➢ The minimum value for synchronous fieldbus operation is equal
to the cycle time of the middle interrupt level (the task "mid irq)
Value is22
mid irq = minimum

Further allowed values for the sync interval are multiples of "mid irq“. With is22 = 0,
multiples of 500µs, i.e. 1ms, 1.5ms etc.
