AS-i protected mode
At a Glance The AS-i protected operating mode is the mode generally used for an application which is running.
It is assumed that the TSX SAY 100 module is configured in PL7.
This: l continually checks that the list of detected slaves is the same as the list of expected slaves.
l monitors the power supply.
In this mode, a slave will only be activated if it has been declared in the configuration and been detected.

At a Glance The Wiring test mode, particularly useful when starting new installations, is used to display on the front panel of the TSX SAY 100 module: l l l expected and detected slaves, unexpected and non-detected slaves, expected and non-detected slaves, or unexpected and detected slaves.
For each slave present on the bus, this mode can also be used to display the state of I/O bits.
Note: LDS and LAS lists, as well as slave adjustment parameters, cannot be accessed in this mode.
Access conditions l l
The wiring test mode is an AS-i function which can be accessed when: l the TSX SAY 100 module is in non-configured mode.
This mode is obtained when: l the TSX SAY 100 module has not been declared in the application, l the PLC processor is missing.
each device has a unique address,

251
AS-i operation
AS-I offline operating mode
At a Glance The AS-i offline mode is an advanced operating mode which can be used in debugging or maintenance.
Note: To use it, you must be thoroughly familiar with AS-i communication.
Principle
Procedure
When offline mode is engaged, the module first resets all the present slaves to zero and stops exchanges on the bus.
During offline mode, the I/O image in the module is frozen in the state that is was in when the offline mode started.
On module output, if the list of present slaves (LPS) is the same as the list of detected slaves (LDS), the system restarts. If this is not the case, a fault is generated and you must refer to diagnostics mode or go back to the configuration.
The offline operating mode can be accessed either: l l from PL7 application software by acting on bits 0 and 1 of the word %MWxy.0.24, automatically when an AS-i power supply fault is detected.
Remember: Bit 7 of word %MWxy.0.24 set on 1 indicates that the AS-i bus is in
offline mode.

TLX DS 57 PL7 xx
AS-i operation
AS-i data exchange off operating mode
At a Glance The AS-i data exchange off mode is an advanced operating mode which can be used in debugging or maintenance.
Note: To use it, you must be thoroughly familiar with AS-i communication.
Principle
Procedure
When the offline data exchange mode is engaged, exchanges on the bus continue to function, but data is not longer refreshed.
The data exchange off operating mode can be accessed from PL7 application software by acting on bits 2 and 3 of the %MWxy.0.3 word.
Remember: Bit 8 of word %MWxy.0.3 set on 1 indicates that the AS-i bus is in data
exchange off mode.

AS-i scanning time
AS-i response time
Example
The AS-i bus is independently managed by the master. This exchanges data on each cycle with each slave device configured on the bus (in ascending order of slave address number).
t scanning time represents the exchange time between the master and n slaves (31 maximum).
Either: l l t = 156 micro seconds x (n+2), if n < 31, t = 156 micro seconds x (n+1), if n = 31.
Thus the scanning time cannot exceed 5 ms.
T response time represents the AS-i cycle time.
l l l
This includes: the bus scanning time, the update of the AS-I module internal memory, the PLC cycle.
The table below shows three examples of T response time for a PLC task lasting 10 ms, 30 ms, and 60 ms.
This T time is for a bus loaded with 31 slaves operating normally with no link faults.

Introduction to the AS-i V2 Bus
Introduction
AS-i V2 Bus
The AS-i Bus (Actuator Sensor-Interface) allows the interconnection on a single cable of sensor devices/actuators at the lowest level of automation.
These sensors/actuators will be defined in the documentation as slave devices.
To implement the AS-i application you need to define the physical context of the application into which it will integrated (rack, power supply, processor, modules, ASi slave devices connected to the bus) then ensure its software implementation.
l l
This second aspect will be carried out from the different PL7 editors: either in local mode, or in connected mode; in this case the modification is limited to certain parameters.
l l l l
The coupler TSX SAY 1000 integrates the functions AS-i V2.
The AS-i bus then allows: up to 62 standard and/or extended address slaves, up to 248 inputs and 186 outputs, up to 124 analog values integrated in the master AS-i, a cycle time of 10ms maximum.

AS-i V2 Bus
Architecture of TSX SAY 1000 Module
At a Glance The TSX SAY 1000 module operates according to the master/slave mode. The master only controls exchanges on the bus.
The AS-i standard sets several operating levels offered by the master: l Profile M0 and M0e - Minimum Master: the master only puts forward the configuration of slaves connected to the bus on power-up, and only input/output exchanges.
Profile M1 and M1e - Full Master: this profile covers all the operating functions set l l by the AS-i standard,
Profile M2 and M2e - Reduced Master: this profile corresponds to profile M0 operating functions with a slave-parametering option.
The master profiles with an "e" support extended profiles.
Note: The TSX SAY 1000 module has an M2e profile, with the additional option of reading slave and slave channel diagnostics information.
The module includes data fields which are used to manage the lists of slaves and I/
O data images. This information is stored in a volatile memory.

At a Glance
Precautions of
Use
The TSX SAY 1000 module supports AS-i security devices on its bus. The addresses of these devices can be configured by PL7 software.
The AS-i security product consists of a Monitor and one or more slaves. The bus master sees these devices as standard address slaves, but with a special profile.
There is a Security Module family on the Configuration Screen (See How to define
a slave device on the AS-i V2 bus, p. 274).
Input/Output objects from these devices should not be used in the application program, as their values are not significant.
The diagnostics information on the Security Monitor may, however, be utilized by the
DFB supplied with this product.

Automatic replacement of a faulty AS-i V2 slave
Principle When a slave has been declared faulty, it can be automatically replaced with a slave of the same type.
This happens without the AS-i V2 bus having to stop, and without requiring any manipulation since the configuration mode's Automatic addressing utility is active
(see How to modify the general parameters of an AS-i V2 slave: Automatic
Two options are available: l The replacement slave is programmed with the same address using the pocket programmer, and has the same profile and sub-profile as the faulty slave. It is thus automatically inserted into the list of detected slaves (LDS) and into the list of active slaves (LAS), l The replacement slave is blank (address 0 (A), new slave) and has the same profile as the faulty slave. It will automatically assume the address of the replaced slave, and will then be inserted into the list of detected slaves (LDS) and into the list of active slaves (LAS).

How to insert a slave device into an existing AS-i V2 configuration.
At a Glance
Procedure
It is possible to insert a device into an existing AS-i V2 configuration without having to use the pocket programmer.
This operation is possible once: l the configuration mode's Automatic addressing utility is active (See How to modify the general parameters of an AS-i V2 slave: Automatic addressing, l l l l
a single slave is absent in the physical configuration, the slave which is to be inserted is specified in the PL7 configuration, the slave has the profile and sub-profile expected by the configuration, the slave has the address 0 (A).
The AS-i V2 module will therefore automatically assign to the slave the value predefined in the configuration.
The following table shows the procedure for making the automatic insertion of a new slave effective.

Step
1
Action
Add the new slave in the configuration screen in local mode.
Carry out a configuration transfer to the PLC in connected mode.
Physically link the new slave with address 0 (A) to the AS-i V2 bus.
Note: An application can be modified by carrying out the above manipulation as many times as necessary.
