Functions
I/O assignment
Each module is functionally organized into groups of 8 channels. Each group of
channels can be assigned to a specific application task.
Reactivation of outputs
If a fault has caused an output to trip, the output can be reactivated if there is no
other fault on its terminals. The reactivation command, defined during configuration,
can be automatic (reactivation every 10 s) or controlled via the program.
Reactivation is carried out in groups of 8 channels. This function is accessible on
modules with DC transistor outputs. For modules with relay and triac outputs
protected by fuses, the same type of reactivation (automatic or via program) is
necessary after replacement of one or more fuses.
RUN/STOP command
An input can be configured to control the RUN/STOP changeover for the PLC.
This is taken into account on a rising edge. A STOP command via an input takes
priority over a RUN command via a terminal or a network command.
Output fallback
If the application switches to STOP, the outputs must be set to a state which is safe
for the application. This state, called the fallback position, is defined for each module
when its outputs are configured.
This configuration is used to select:
b
Fallback: the channels are set to 0 or 1 according to the defined fallback value
b
Maintain: the outputs maintain the state in which they were before the stop
occurred
Diagnostic functions
b
Module diagnostics: any exchange fault, preventing normal operation of an output
module or fast input module is indicated. Similarly, any internal module fault is
indicated.
b
Process diagnostics: sensor/preactuator voltage check, terminal block presence
check, short-circuit and overload check, sensor voltage check, preactuator voltage
check.
Specific functions of TSX DEY 16FK/DMY 28FK module inputs
b
Latching: enables particularly short pulses, with a duration shorter than the PLC
scan time, to be taken into account.
b
Event-triggered inputs: enables events to be taken into account and ensures they
are processed immediately (interrupt processing). These inputs are associated with
the event processing (EVTi) defined in configuration mode where: i = 0…31, 0…63
or 0…128 according to the type of Premium CPU.
b
Event processing can be triggered on a rising edge (0
1)
or a falling edge (1
0)
of
the associated input. Amasking/unmasking function for

inputs is available in online mode.
b
Programmable input filtering: the inputs are equipped with filtering which can be
configured for each channel. Inputs are filtered by a fixed analog filter which provides
a maximum immunity of 0.1 ms for filtering line interference and by a digital filter
which can be configured from 0.1 to 7.5 ms in increments of 0.5 ms.
Reflex and timer functions for the TSX DMY 28RFK module
These control system functions are used to create applications which require a faster
response time than the fast task or event processing (< 500
s). They are executed
in the module and are independent of the PLC task. They are programmed using
Unity Pro or PL7 Junior/Pro software in configuration mode.
Hot swap
Due to their integrated devices, the I/O modules (including application-specific
modules) are hot-swappable.
