Introduction
The following example shows the information required to operate a AS-i field device on a 140 EIA 921 00 AS-i Master module using Control Expert.
An inductive proximity switch (type XS1) is connected as Slave 1 and Signal column (type XVB) as Slave 2.

Addresses and functions
The input signals for the AS-i field device shold be mapped in the input word area %IW101 to %IW113, the output command to the AS-i field device are found in words %MW 201 to %MW209.
The flashing light operational display for the inductive proximity switch should be deactivated.
Elements 2 and 3 of the signal column should be configured as flashing lights, the other elements as continuous lights.
Data transfer
You can transfer the following information from the data sheets for configuring the 140 EIA 921 00:

Data access
You can take the assignment of the AS-i field device I/O bits to the internal addresses in the Control Expert program from the inputs and outputs mapping table. Word 1 in the input mapping table corresponds to %IW101 and word 1 in the output mapping table corresponds to %MW201.
