SYNCH Cycle
RxPDO
When there is any change for RxPDO, RxPDO data is
transmitted to slave and the PxPDO that slave receives is
valid immediately. When there is no change for RxPDO,
master does not send RxPDO data to slave.
254
TxPDO
When Event timer and inhibit timer are both 0, TxPDO data
is transmitted to master after TXPDO data changes and
the data that master receives will be invalid immediately;
when TxPDO data does not change, slave does not send
out TxPDO data to master.
When neither of Event timer and inhibit timer are 0, slave
sends out TxPDO data to master once every a period of
Event timer. After TxPDO data is sent out once, no TxPDO
data is allowed to be sent out within the period of inhibit
timer and when TxPDO data changes, TxPDO data is
transmitted to master at once and the data that master
receives will be valid immediately.
