A/B slaves for expanding the address space to 62 slaves in an AS-Interface network
Adapter is a passive device in a ControlNet with respect to cyclic data traffic.
It cannot independently establish a cyclic connection to another node but acyclic connections are always possible.
Analog module for transmitting up to 24 bit analog values utilizing a sequential data transfer
AS-Interface power supply for supplying the whole system with
power while concurrently decoupling
the data
AT drive telegram, each slave sends its AT during the corresponding time slot
Bit strobe Multi/Broadcast I/O data exchange
Bootup Node start-up sequence
CIP (Control and Information Protocol) describes the means of addressing in order to create a connection to a communication object in a ControlNet node.
Consumer device that receives data
Consumer/ Producer describes the process for characterizing and addressing data within a ControlNet system.
