CM - PROFIBUS V. 1.6
23.6.17
Identical with protocol "Layer 2 11Bit" (see chapter 14.3.2) However there are additional configu-
rations possible on the fieldbus side:
Fieldbus trigger byte (i.e. fieldbus data exchange = On Trigger), fieldbus length byte and swap
word.
Die Scriptdurchlaufzeit erhöht sich da zusätzliche Routinen durchlaufen werden.
14.3.4 Universal (L2 11Bit) with COB-ID used
Additional configurations are possible:
Up to 16 COB-ID’s can be configured to which the CAN interface can react to.
All others are filtered (not processed).
If the value “0000” is displayed in the first entry „(CM) COB-ID used(1/16)” it will also be reacted
to messages with COB-ID NULL
If in one of the other entries „(CM) COB-ID used(2…16/16)“ the value is NULL, it is considered
the end of the list and all subsequent entries will not be processed.
Example:
In this example only the COB-ID´s „0000“ (hex), „0181“ (hex), „0201“ (hex) and „0080“ (hex) are
processed, i.e. transferred to the fieldbus.
14.3.5 Universal (L2 11/29Bit)
A maximum of 13 Byte of data are displayed on the fieldbus side (1 Byte frame info, 4 Byte COB-
ID, 8 Byte payload).
Additional configurations on the fieldbus side are possible:
Fieldbus trigger byte (i.e. data exchange = On Trigger), fieldbus length byte and Swap word.
Data display on the fieldbus side (SPS receives CAN) „11 Bit Mode“:
