Modification of the internal values by program
The TSX DMY 28 RFK module reuses the language objects of standard discrete modules (see the Language objects associated with the discrete specific
It does however have two explicit exchange objects, specific to the reflex outputs, l l which enable the internal values of the function blocks to be modified (e.g.: th1, th2 for a 2 threshold counter).
These objects are as follows:
%MWxy.i.4 which contains the first internal value of the function block,
%MWxy.i.5 which contains the second internal value of the function block,
Other than the standard instructions (see Explicit exchange language objects
associated with module TSX DMY 28 RFK , p. 197), the TSX DMY 28 RFK module
also uses a specific instruction MOD_PARAM (Modify parameters) which enables the parameters associated with a single channel to be modified.
Syntax: MOD_PARAM %CHxy.i (no., value1 , value2 , 0) where: l l i = 16 or 24 (index of the first channel of a group of 8 channels), no. = 0 to7 (index of the channel in the group of channels).
Example:
Modification of parameters of channel 18 (value 01 = 10 ms (100 x 0.1 ms) , value
2 = 500 ms (5000 x 0.1 ms))
MOD_PARAM %CHxy.16 (2, 100 , 5000 , 0)

AS-i Bus
Presentation of the AS-i Bus
At a Glance 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, supply, processor, modules, AS-i 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.

AS-i Bus
Architecture of the TSX SAY 100 module
At a Glance The TSX SAY 100 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 - Minimum Master: the master only puts forward the configuration of l slaves connected to the bus on power-up and input/output exchanges.
Profile M1 - Full Master: this profile covers all the operating functions set by the
AS-i standard, l Profile M2 - Reduced Master: this profile corresponds to profile M0 operating functions with a slave-parametering option.
Note: The TSX SAY 100 module has an M2 profile, with the additional option of reading slave 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.

AS-i bus configuration
How to modify AS-i slave general parameters: Automatic addressing
At a Glance Each slave on the AS-i bus must be assigned (via configuration) a unique physical address. This must be the same as the one declared in PL7.
PL7 software offers an automatic slave addressing utility so that an AS-i console does not have to be used.
The automatic addressing utility, which can be accessed via PL7, is used for: l l replacing a faulty slave (See
inserting a new slave (See How to insert a slave device into an existing AS-i
Automatic replacement of a faulty AS-i slave,
Note: A new configuration with automatic addressing will not be accepted if one or more slaves with a 0 address are on the bus. In this case, the Configuration refused by module message appears.
Procedure The table below shows the procedure for setting the Automatic addressing parameter.
Step

How to modify AS-i slave general parameters: Fallback mode
At a Glance This parameter sets the fallback mode which slave outputs take on while switching to STOP mode or if there is a PLC fault.
Possible modes are: l Fallback to 0: AS-i slave outputs which are present on the bus are set to 0 (%Q l objects are not modified),
Maintain state: AS-i slave outputs remain in the state they were before STOP mode was engaged.
Note: The fallback mode for slaves which do not have a watchdog (AS-i bus monitoring function) is not guaranteed in case of an AS-i bus fault, or AS-i power supply failure. For slaves with a watchdog, the fallback position is preset within the device.
Procedure The table below shows the procedure for setting the Fallback mode assigned to slave device outputs.
Step

Action
Access the AS-i communication module’s configuration screen.
Click on the Fallback to 0 / Maintain state check-box found in the General

How to access functionality in the module diagnostics and channel diagnostics for an AS-i device
At a Glance
Procedure for accessing the module diagnostics
The functions of the module or channel diagnostics display the current errors in which are classed according to their category: l internal errors (internal software errors, communication error with the processor, configuration, parametering or command error), l l external errors(slave device failed, AS-i supply switched off, terminal error, difference between physical configuration and PL7 configuration), other errors (module absent or switched off).
A faulty module becomes apparent when certain lights change to red, such as: l in the configuration editor at rack level: l the module position light, l in the configuration editor at module level: l the lights RUN, ERR and I/O, l the light DIAG.
A faulty channel becomes apparent when certain lights change to red, such as: l in the configuration editor at rack level: l l the module position light, in the configuration editor at channel level: l the light DIAG.

Automatic replacement of a faulty AS-i 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 bus having to stop, and without any particular manipulation since the configuration mode Automatic addressing utility is active
(see
How to modify AS-i slave general parameters: Automatic addressing, p. 219).
Two options are available: l The replacement slave is programmed with the same address using the pocket programmer, and has the same profile as the faulty slave. It will then be automatically inserted into the list of detected slaves (LDS) and list of active slaves (LAS).
l the replacement slave is blank (address 0, 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 the list of active slaves (LAS).

How to insert a slave device into an existing AS-i configuration.
At a Glance
Procedure
It is possible to insert a device into an existing AS-i configuration without having to use the pocket programmer.
This operation is possible as soon as: l the service Automatic addressing of the configuration mode is active (See How
to modify AS-i slave general parameters: Automatic addressing, p. 219),
l l l l a single slave is absent in the physical configuration, the slave which is to be inserted is projected in the PL7 configuration, the slave has the profile expected by the configuration, the slave has the address 0.
Therefore the AS-i interface card will automatically assign to the slave the value predefined in the configuration.
The following table presents 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.
Do a configuration transfer to the PLC in connected mode.
Physically link the new slave with address 0 to the AS-i bus.
Note: It is possible to modify an application by carrying out the above manipulation as many times as necessary.
