DVP-PLC Operation Manual 24 Transmission Type Description Remark 3～240 RxPDO To analogize on basis of transmission type 1 and 2 SYNCH Cycle TxPDO To analogize on basis of transmission type 1 and 2 254 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.
ASYNCH 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. 255 RxPDO Same as transmission type:
