<strong>Sensor</strong><br />

A device which detects and relays a status or a measured<br />

quantity, e.g. sensors for distance measurement<br />

(inductive, capacitive, photoelectric, ultrasonic, etc.).<br />

Safety category (as defined in EN 954-1)<br />

Classification of safety-related components with respect<br />

to their resistance to error and behavior in case<br />

of error, which is achieved based on the structural arrangement<br />

of parts and/or their reliability.<br />

Slave<br />

Passive participant on the bus. It will only respond<br />

when addressed. Slaves are identified by their addresses.<br />

The factory setting for <strong>AS</strong>-<strong>Interface</strong> slaves is<br />

address 0.<br />

Message<br />

A message sent by the master, or a message sent in<br />

reply by a slave.<br />

Transfer rate<br />

Transfer speed of the bits on the bus line. Measured in<br />

bit/s = Baud (Bd).<br />

Cycle time<br />

Period of time until an addressed slave is addressed<br />

again. The cycle time is more significant than the<br />

transfer rate. The fewer slaves there are, the shorter<br />

the cycle time.<br />
