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:
8 Byte * 8 Bit = 64 Bit * 2
s = 128
s
Overhead RxPDO2:
8 Byte * 8 Bit = 64 Bit * 2
s = 128
s
User data RxPDO2:
2 Byte * 8 Bit = 16 Bit * 2
s = 32
s
Overhead RxPDO3:
8 Byte * 8 Bit = 64 Bit * 2
s = 128
s
User data RxPDO3:
8 Byte * 8 Bit = 64 Bit * 2
s = 128
s
Overhead RxPDO4:
8 Byte * 8 Bit = 64 Bit * 2
s = 128
s
User data RxPDO4:
3 Byte * 8 Bit = 24 Bit * 2
s = 48

At a cycle time of 10 ms this corresponds with a bus load of 16.48%.
34.9.1.3 Calculation of the power consumption:
The CECX-B-CO makes 8.5 W available for add-on modules.
Add-on modules:
CECX-D-8E8A-NP-2: 0.4
W
CECX-D-8E8A-NP-2: 0.4
W
Total:
0.8 W < 8.5 W
34.9.1.4 Calculation of the bus load:
Determined:
Baud rate: 500 kBit Cycle time: 2 ms
Data volume:
