13.2.2Active/Passive State
The α series can be switched from an Active to a Passive state on the AS-interface network by changing the state on the N01 Control Icon. In the Active State, N01=0, communication is possible over the network. This icon can be found in the “Out” Menu next to the AS-interface “Link Out” icon.
When multiple α series are added to a network, each slave must be given an address. In order to address the slaves from the Master station, only one unaddressed slave can be active at any one time. Once a slave has an address, another passive slave can be turned to an active state to receive its address.
Please refer to the α and α2 series Programming Manuals, the AL/AL2-ASl-BD Hardware Manual and the manual for the AS-interface Network Master Controller.
