3.1.2.5 Node Address

The node address (decimal) is determined using two rotary switches on the

electronic module.

Fig. 3-5: Setting the node address gxxxx08x

The binary significance of the individual DIP switches increases according to

the switch number, i.e. the module ID 1 is set by DIP1 = ON, the module ID 8

by DIP4 = ON, etc.

The binary value (2

–2

) of the dip switches increases from switch 1 to switch

8, a logic 1 being represented by “ON“.

default setting

Node addresses between 0 and 127 can be set.

If an invalid address is set, the coupler adopts the address that has been

assigned via Set_Slave_Address. This address is stored in the power fail safe

EEPROM. The default address is 126.

The node address is saved in the Fieldbus Coupler after switching on the

device (initialization phase). Adjustments of the switch have no effect during

operation.
