8.3.1.11 Process data objects
The OGS 600 provides 4 transmit process data objects (TPDOs) and 1 receive process data
object (RPDO).
The TPDOs describe which objects are mapped to (integrated in) the TxPDO, and define
the access (synchronous/asynchronous) to these objects.
• TPDO1: Status, contrast, number of detected traces, 1st edge and 2nd edge
• TPDO2: 3rd to 6th edge
• TPDO3: 7th to 10th edge
• TPDO4: 11th and 12th edge
The communication parameters of the PDOs are determined via defined objects. Synchro-
nous or asynchronous access, a possible inhibit time for the PDO object in the CAN network
as well as an event timer are defined in these objects.
• TPDO1: object address 1800
h
• TPDO2: object address 1801
h
• TPDO3: object address 1802
h
• TPDO4: object address 1803

Asynchronous transfer is controlled by the event timer in the PDOx property objects 1800
h
to 1803
h
.
Synchronous transfer is initiated by a SYNC telegram (80
h
) sent from the master, as well as
by the PDOx property objects 1800
h
to 1803
