6.5.2.1 LEDs CANopen slave for b maXX PLC
Switch on and
initialization
After switching on the LEDs are lightning for a short time in sequence H4 (red), H3
(green), H2 (red), H1 (green).
Then the option module CANopen slave is initialized.
Following pattern is displayed:
Start of initialization: H1 on, H2 to H4 off
End of initialization: H3 on, H1, H3, H4 off
Initializing finished: H1 to H4 off
The basis initialization of the option module CANopen slave is finished.
If the initialization was not done without error then the LEDs H2 and H4 are blinking syn-
chronously.
In this case refer to ZError detection and trouble shooting– from page 39 for further infor-
mation.
Commissioning After initialization of the option module CANopen slave an application program on the
b
maXX PLC can configure it.
The option module CANopen slave displays with LED H1 to H4 off, that it is waiting for
PLC configuration.
In the manual to the b maXX PLC this configuration is called „Initialization CANopen slave
on the option module CANopen slave for b maXX PLC“, also.
Further information see „Application handbook b maXX PLC“ and „Application handbook
CANopen slave for b maXX PLC“.
After configuration of the option module via the application program on the b maXX PLC
the LEDs H1 and H2 correspond with the CiA specification DR303-3. LEDs H3 and H4
are reserved.
H1 single flash CANopen slave is in state STOPPED
H1 blinking CANopen slave is in state PRE-OPERATIONAL
H1 on CANopen slave is in state OPERATIONAL
single flash: ca. 200 ms on, then ca. 1000 ms off
blinking: ca. 200 ms on, then ca. 200 ms off
H2 (red) is normally off, otherwise an error occurred,
see ZError detection and trouble shooting– from page 39 for trouble shooting.
