System manual CECX / Bus link module CECX-B-CO
The PDO is set together of one data overhead (addressing, object num-
bers,...) with 8 Byte and the user data specified above. The data transfer
time is 2
s per Bit. (For further information: see the chapter "Baud-rates-
and address settings")
Overhead RxPDO1:
8 Byte * 8 Bit = 64 Bit * 2
s = 128
s
User data RxPDO1:
2 Byte * 8 Bit = 16 Bit * 2
s = 32
s
Overhead TxPDO1:
8 Byte * 8 Bit = 64 Bit * 2
s = 128
s
User data TxPDO1:
2 Byte * 8 Bit = 16 Bit * 2
s = 32
s
Overhead Sync-Signal:
8 Byte * 8 Bit = 64 Bit * 2
s = 128
s
Total: 448
s
At a cycle time of 2 ms this corresponds with a bus load of approx. 25%.
34.10 Object directory
All communication objects and all application objects are grouped together
in the object directory. In the CANOpen device model the object directory
forms the link between the application and the CANOpen communication
unit.
Each entry in the object directory represents an object and is identified by a
16-bit index. An index in turn can contain up to 256 sub-indices. This en-
ables the differentiation of 254 element up to 65536 * independent of the
"11-bit identifiers". (The sub-indices 0 and 255 cannot be freely used.)
In profiles the assignment of communication and device objects to a re-
spective index is precisely defined; this means that with the object directory
a unique interface is defined between the application and communication
toward the outside.
For example, every CANOpen node in the network knows that at index
1017h the heartbeat interval is located, and every node or configuration
program has access to it for reading or writing.
The object directory contains all objects that exist independent of the K-Bus
configuration, but whose properties are partly dependent on the K-Bus con-
figuration.
In addition, every type of supported K-Bus module contains a set of objects,
which will only be displayed in case a corresponding K-Bus module exists.
