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).
