6.4.2.1 Activating and initializing
After switching on, the LEDs flash briefly one after the other: first the green one and then
the red one.
After this, the CANsync-Master option module is initialized. When doing this, the system
displays the following pattern:
Start of initialization H1 on, H2 off
Initialization running H1 and H2 on
End of initialization H1 on, H2 off
Initialization completed H1 and H2 off
This completes initialization of the CANsync-Master option module.
If an error occurred at initialization, LED H2 flashes.
To find out how to eliminate the cause of the error, refer to Z Finding and eliminating dis-
turbances – from page 35 onward.
6.4.2.2 Operation
After initializing the CANsync-Master option module, an application program on the
b maXX PLC can configure the option module.
Now, the CANsync-Master option module shows H1 = ON to indicate that is waiting to be
configured by the PLC. In the case of the b maXX PLC option module, we also refer to
configuration of the CANsync-Master option module as "initializing the CANsync-Master
adapter on the CANsync-Master option module for b maXX PLC".
For configuration, see the "b maXX PLC Operating Instructions", the "b maXX PLC Ap-
plication Manual" and the "CANsync Application Manual“.
After an application program on the b maXX PLC has configured the option module, the
LEDs have the following meanings:
H1 (green) shows message frames being received and sent to the CANsync-
Bus an.
H2 (red) is normally off and only flashes in the case of a fault.
