PQ-Link communication opto-isolated serial link connector
22 Filter unit address selector (3 Left most DIP switches with ABB Logo at top
left side) and CAN bus termination (Right hand DIP switch):
Symbols used: L: low – H: high
Address 1: Position of the 3 switches starting from left: L L L
Address 2: Position of the 3 switches starting from left: H L L
Address 3: Position of the 3 switches starting from left: L H L
Address 4: Position of the 3 switches starting from left: H H L
Address 5: Position of the 3 switches starting from left: L L H
Address 6: Position of the 3 switches starting from left: H L H
Address 7: Position of the 3 switches starting from left: L H H
Address 8: Position of the 3 switches starting from left: H H H
Note: In a multi-master arrangement, the master which is operational and
which has the lowest address controls the system.
The default address setting is L L L
