System manual CECX / Bus link module CECX-B-CO
Data transfer time
The data transfer time is required to calculate the bus load. It also specified
how long the transfer of a single Bit takes.
Baud rate Data transfer time per Bit
125 kbit/s
8 s
250 kbit/s
4 s
500 kbit/s
2 s
800 kbit/s
1,25 s
1 Mbit/s
1 s
Address
The CAN-address (Node ID) is set via the two address switches in the
range from 1 (0x01) to 127 (0x7F) of the CECX-B-CO. The addresses 0x00
and 0x80 to 0xFF are invalid.
Example:
Node ID = 29 (Ox1C) ADRH: 1 ADRL: C
The firmware adopts the set address once during start-up of the CECX-B-
CO. It is not possible to change the address during operation.
Information
If the address setting is invalid, the communication with the CECX-B-CO is
disabled (Status LED illuminates red).
34.7.3 Creation of the default PDO mapping
In principle the Default PDO-Mapping contains a type-pure PDO-structure;
i.e. analog and digital data are not mixed in one PDO.
The Default PDO-Mapping is created according to the CANOpen specifica-
tions of the DS 401 2.0. Due to the type-purity the PDOs can also remain
unused and/or have omissions.
To establish a connection between the data objects mapped in the PDOs
and the IO-connections of the hardware, the K-Bus module mapping is
used.
Information
The CECX-B-CO sorts the modules on the bus in the following order:
1 CECX-E-6E-T-P2 2. CECX-A-4E4A-V 3. CECX-A-4E4A-A
4. CECX-A-4E-V 5. CECX-A-4A-V 6. CECX-E-4E-T-P1
7. CECX-D-16E 8. CECX-D-14A-2 9. CECX-D-8E8A-NP-2
10. CECX-D-6E8A-PN-2 11. CECX-C-2G2 12. CECX-C-2G1
CECX-II 34-14
