The code supplied by the transponder has a sequence of 24 bits in which 16 bits are
coded. The data and a status byte are output via the CAN-Bus. Transponders can
also be programmed via the CAN-Bus. The serial interface, that is also available, can
be used for logging and for configuration via the internal monitor program (see chap
-
ter 9 on page 49).
The Node-ID (see section 7.2 on page 37) and the CAN transmission rate (see sec
-
tion 9.4.3.3 on page 55) must be set.
The measured values of the system (transponder code and status) are transmitted
via a so-called TPDO. Commands such as switching off the transmitter and deleting
the last transponder code are transmitted via an RPDO. SDOs or the monitor pro
-
gram (see section 9.4.3 on page 54) are used for parametrization of the communi
-
cation parameters. The CAN identifiers are derived from the node address (1..127).
7.1 Definitions CAN and CANopen®
The CAN or CANopen® configuration is structured according to ISO 11898 or EN
50325-4. Important terms and abbreviations are explained in this section as small
assistance. For further information, you can consult the standards or go to
http://www.can-cia.org/en/standardization/technical-documents/
and download the technical specifications of the CANopen® standards after a free
registration. For devices that support CANopen®, EDS (Electronic Data Sheet) files
can be downloaded from the Götting website (see section 7.11 on page 46). The
complete configuration is stored in these files. CANopen® Magic from PEAK System
is an example of a program that can be used to access EDS files:
Note that not every device supports every operating mode. Götting devices normally
support operating modes 1 to 240 and 255.
