AS-i Bus

PLC Programming/Other Gateways

03/00

Software Setup

The AS-i bus is configured using PL7 Micro/Junior/Pro software. The utilities available are based on the

principle of simplicity:

• Management of profile tables, parameters, and data by the master (this management is transparent

to the user).

• Topological I/O addressing: each AS-i slave declared on the bus is assigned a topological address

on the bus by the user. This is transparent to the user.

• Each sensor/actuator on the AS-i bus is treated as an in-rack I/O by the Micro/Premium PLC.

AS-i Bus Configuration

All devices on the AS-i bus are configured implicitly using the following sequence of screens:

Declaration of the AS-i bus master module

• The TSXSAZ10 module is always inserted and

declared in position no. 4 on TSX37-10 or

TSX37-21/22 PLCs.

• The TSXSAY100 module is inserted into any

position on TSX57, TPMX57, or TPCX57 PLCs

(except the position reserved for processors and

power supply).

Configuration of the AS-i slave devices

Using the configuration screen, it is possible to

configure all the slave devices (1 to 31), i.e. all

248 I/O. Configuration for each device consists of

defining, according to case:

• Groupe Schneider AS-i devices. The user selects

the AS-i device catalog number from the various

product families. This selection determines the

AS-i profile and the parameters associated with the

device.

• Third party AS-i devices. The user can use PL7

Micro/Junior software to manage a “customized” list

of sensors/actuators of different brands. This list,

specifying the AS-i profile and parameters, is

compiled to meet the needs of the user.

The configuration screen is also used to:

• Associate a symbol with each AS-i input or output

(up to 32 characters)

• Define the default position of the actuators for all

devices (set to state 0 or maintained) should the

Micro/Premium PLC stop.

Programming

After configuration, the I/O connected on the AS-i bus are processed by the application program in the

same way as a PLC in-rack I/O, using either the address (e.g. I\4.0\16.2, input 2 of slave 16 of the

AS-i bus) or the associated symbol (e.g. Start_conveyor).
