IM 353CAN - CANopen slave - Baud rate and module-ID
You have the option to specify the baud rate and the module-ID by setting
the address selector to 00 within a period of 10s after you have turned the
power on.
The selected settings are saved permanently in an EEPROM and can be
changed at any time by means of the procedure shown above.
• Set the address selector to 00 .
• Turn on the power to the CAN-Bus coupler.
The LEDs ER, RD, and BA will blink at a frequency of 1Hz. For a period
of 5s you can now enter the CAN baud rate by means of the address
selector:
Address selector CAN baud rate max. guar. bus distance
"00" 1Mbaud 25m
"01" 500kBaud 100m
"02" 250kBaud 250m
"03" 125kBaud 500m
"04" 100kBaud 600m
"05" 50kBaud 1000m
"06" 20kBaud 2500m
"07" 10kBaud 5000m
"08" 800kBaud 50m
After 5 seconds the selected CAN baud rate is saved in the EEPROM.
• LEDs ER and BA are turned off and the red RD-LED continues to blink.
At this point you have 5s to enter the required module-ID
• Define the module-ID in a range between 01...99 by means of the
address selection switch. Every module-ID may only exist once on the
bus. The module-ID must be defined before the bus coupler is turned
on.
The entered module-IDs are accepted when a period of 5s has expired
after which the bus coupler returns to the normal operating mode
(status: "Pre-Operational").
You can also modify the CAN baud rate by means of an SDO-Write
operation to the object "2001h". The entered value is used as the CAN
baud rate when the bus coupler has been RESET. This method is a most
convenient when you must change the CAN baud rate of all the bus
couplers of a system from a central CAN terminal. The bus couplers use
the programmed baud rate when the system has been RESET.
