Process data transfer

Transmission type

Process data objects can be transmitted in an event-controlled or time-controlled manner.

Event-controlled: The PDO is sent when a special device-internal event has occurred,

for instance when the data contents of the TPDO have changed or when a transmission

cycle time has elapsed.

Synchronous: A TPDO (or RPDO) is transmitted (or received) after the device has

received a sync telegram (with the identifier 0x80).

Cyclic: The transmission of PDOs takes place at fixed time intervals after the

transmission cycle time has elapsed.

The following table shows that combinations of the different transmission methods by

means of logic operations (AND, OR) are also possible:

The communication parameters of each PDO (e.g. transmission mode and cycle time) can

be set freely and independently of the settings of other PDOs:

Tip!
The setting can also be made via the following CANopen objects:

Description

0

The PDO is transmitted on an event-controlled basis with every sync (e.g. when a bit change

occurs in the PDO).

1 ... 240

Sync (with response)

• Selection n = 1: The PDO is transmitted with every sync.

• Selection 1 < n ≤ 240: The PDO is transmitted with every nth sync.

254, 255

Event-controlled (with mask) with cyclic overlay

If this value is entered, the PDO is transmitted in an event-controlled or cyclic manner.

(Note: Currently the values "254" and "255" have the same meaning.)

Cyclic overlay is given if a cycle time is set for the respective PDO. In this case, cyclic

transmission takes place in addition to event-controlled transmission (e.g. when a bit

change occurs in the PDO).
