4.11.2  Operation modes process data channel 
  The transmit/receive behavior can be time controlled or controlled via a SYNC tele-
gram. The behavior can be parameterized for each PDO channel. 
  Tx-PDO’s can work time controlled or SYNC controlled. A time controlled TxPDO
transmits its data at the interval of time set. A SYNC controlled TxPDO transmits its
data after the arrival of a SYNC telegram. 
  RxPDO’s in the time controlled settin
g
 forward the received data to the application
immediately. If an RxPDO has been defined as SYNC controlled, its forwards its re-
ceived data to the application after the arrival of a SYNC telegram.

  Operation mode  Function 
  0 -Not Active  No data are sent. 
  1 -Controlled by time  In the cycle of the adjusted time interval the data 
are sent. 
  2 -Controlled by SYNC  To arrival of a SYNC telegram the data are sent.

The setting of the operation mode is done via the following parameters: 
RxPDO1 Function 936, RxPDO2 Function 937 und RxPDO3 Function 938 
  Operation mode  Function 
  0 -Controlled by time  The received data are passed on immediately. 
  1 -Controlled by SYNC  After arrival of a SYNC tele

are passed on. 
  Note:  In the "controlled by time” operation mode, there is a polling of the re-
ceived data with the trigger cycle of Ta = 1 ms.
