Special Hardware Requirements:
Within the scope of the indicated sample system, the following actuator-sensor interface (AS-i) components are used:

For a minimum configuration, at least the components listed under item 1 to item 4 are needed. These components may also be connected with a single round cable.
The interface modules as well as the control device SIGNUM are connected by means of the AS-interface profile cable.
The addressing device is used for setting the slave address.

The slave addresses listed below are used for the sample system. The factory setting for the slaves address is 0. For operation, it has to be set to a value between 1 and 31.

Note! Starting with STEP 7-Micro/WIN Version 3.2.1, a AS-i Wizard was added. As a result, the new wizard now provides an easier method of programming this task than is shown here. Functions of the sample system: Redkey turns the red light on the signal column on/off. Green key turns the green light on the signal column on/off. Active AS-interface sensor 1 turns the flashing light on the signal column on/off. Active AS-interface sensor 2 turns the sensing element on the signal column on/off. Conventional sensor on the IP 65 user module turns the light on the control device on/off. Photoelectric barrier on the IP 20 414Q slave switches all four outputs of the IP 65 4A slave on/off.
