TSX SAZ master module for AS-Interface bus
The TSX SAZ 10 AS-Interface bus module enables the TSX Micro PLC to act as the
AS-Interface bus master. In this way up to 31 sensor/actuator type devices may be
managed on the one AS-Interface bus. Up to 4 inputs and/or outputs can be
connected to each device, giving a maximum of 248 I/O on one segment.
The AS-Interface bus comprises a master station (TSX Micro PLC) and slave
stations. The TSX SAZ 10 module supports the AS-Interface M2 profile, interrogates
the device connected on the AS-Interface bus in turn and stores the data (state of
sensors/actuators, operational status of devices) in the PLC memory.
Communication management on the AS-Interface bus is completely transparent with
regard to the PLC application program.
An AS-Interface power supply for bus must be used for powering the various
components on the AS-Interface bus. Ideally this PSU should be situated nearest to
the stations with the largest current demands.
See page 2/51, Phaseo power supplies.
The TSX SAZ 10 AS-Interface bus master is a half-format module designed to slot
into the basic configurations of TSX 37 10/21/22 TSX Micro PLCs, in position 4 (one
TSX SAZ 10 module per configuration) (1).
The front panel comprises:
1 An opening with locating device for routing AS-Interface bus ribbon or round cable
(to be connected to a terminal block inside the module).
2 Four indicator lamps:
v RUN: the module is active,
v ERR: module fault or bus connection fault,
v COM: AS-Interface bus communication is active,
v AS-Interface: bus configuration error.
3 A pushbutton to transfer the AS-Interface bus display to the PLC front panel.
The TSX Micro PLC centralised display block enables the display of the status of all
the I/O channels, and the diagnostics for devices on the AS-Interface bus (present,
missing, faulty, not conforming to the configuration):
1 Device number.
2 Control pushbutton for accessing the various operating modes of the display
block.
3 State of the 4 device inputs.
4 State of the 4 device outputs.
(1) When the TSX SAZ 10 module is in position 4, the upper position 3 can only receive a
TSX A
p Z pppp analogue or TSX CTZ ppp counter half-format module.
