Controller settings
(Please also note the specifications in the system manual of the controller).
Setting sequence:
1. Set CAN bus node address to value 1 (C0350 = 1).
2. Address for CAN3−IN and CAN3−OUT is to be determined by C0350
(C0353/3 = 0).
3. Set CAN bus baud rate to 500 kBit/s (C0351 = 0).
4. Set CAN bus master operation (C0352 = 1).
5. Set cycle time for cyclic process data transfer (C0356/3 > 0).
6. Change process output words in CAN3−OUT to digital output signals
(C0864/3 = 1).
7. Save set parameters (C0003 = 1).
8. Activate CAN reset node (C0358 = 1).
( Stop!
When status information is sent from the terminal extension, the
entire byte is read into the controller, including the status
information of the digital outputs.
ƒ In the example, the input states are read via
CAN3−IN.B0 ... CAN3−IN.B5 and the output states via CAN3−IN.B6
and CAN3−IN.B7.
ƒ Check the internal links of the input signals CAN3−IN.B6 and
CAN3−IN.B7 at the controller. Set outputs (HIGH level) of the
terminal extension may trigger uncontrolled actions on the
controller.
