5. Now set the node address with the coding switch for the module. You have
five seconds for this.
– Each node address must be assigned only once.
6. The set node address will be accepted after 5 seconds.
– LED RD goes off.
– The module changes to the pre−operational mode.
)
Note!
l
The node address can be changed any time with the coding
switch. The setting is accepted after switching on the supply
voltage.
l
After switching on the supply voltage, the modular system
needs approx. 10 s for initialisation. During this time, the
modules cannot be parameterised.
