Master modules for AS-Interface bus

The AS-Interface bus is configured using PL7 Micro/Junior/Pro software. The

services offered are based on the principle of simplicity:

b Management of profile tables, parameters and data by the master (this

management is transparent to the user).

b Topological I/O addressing: each AS-Interface slave declared on the bus is

assigned a topological address on the bus. This is transparent to the user.

b Each sensor/actuator for the AS-Interface bus interfaces is treated as an in-rack

I/O by the TSX Micro/Premium PLC.

All devices on the AS-Interface bus are configured implicitly using the following

sequence of screens:

b Declaration of the AS-Interface bus master module

v The TSX SAZ 10 module is always inserted and declared

in position no. 4 on

TSX 37 10/21/22 TSX Micro automation platforms.

v TSX SAY 100/1000 modules can be inserted into any position on

TSX/PCX 57 Premium

automation platforms (except positions reserved for

processors and power supplies).

b Configuration of AS-Interface slave devices

Using the configuration screen, it is possible to configure all the slave devices

corresponding to all interface I/Os on the AS-Interface bus. Depending on its type,

the configuration for each device consists of defining, as appropriate:

v Schneider Electric AS-Interface devices.

The user selects the AS-Interface device catalog reference from the various discrete,

analog, or safety interfaces listed. This selection

automatically determines the

AS-Interface profile and the parameters

associated with each interface.

v Third-party AS-Interface device.

The user can use PL7 Micro/Junior software to manage a “customized” list of

sensors/actuators of different brands. This list, specifying the AS-Interface profile

and parameters, is compiled to meet the needs of the user.

After configuration, the I/Os connected on the AS-Interface bus are processed by the

application program in the same way as an in-rack I/O of the PLC, using either the

address (e.g. %I\4.0\16.2, input 2 of slave 16 of the AS-Interface bus), or the

associated symbol (e.g. Start_conveyor).

PL7 Junior/Pro software has an integrated function block library containing the

specific diagnostic DFBs for AS-Interface bus. Its check for the appearance of any

error on the AS-Interface (bus or slaves).
