Real-time based programming
Nano PLCs with 16 or 24 I/O integrate 16 user-definable
real-time clocks which can be used to :
i
Control the outputs directly (opening and closing electrical
circuits) or act on the user program according to the time
(month, day, hour and minute).
i
Program time setpoints which can be modified via an
operator panel or calculated by the program.
i
Program event time-stamping or perform time
calculations.
Analogue I/O
The Nano PLC is designed for simple process control
applications (level, temperature, flow rate control, etc) with
speed controller or servo-valve control.
TSX AEN/ASN modules are used with Nano PLCs to
process 1 analogue input and 1 analogue output respec-
tively :
i
The input module, 0/10 V - 10/+ 10 V or 4/20 mA is
connected to the
a
24 V input %I0.0 of the PLC and is
configured in frequency meter mode.
i
The output module, 0/10 V - 10/+ 10 V or 4/20 mA uses
the pulse width modulation transistor output %Q0.0.
Analogue processing is also possible using three
TSX 07 32/33
ii
28 bases which consist of 1 analogue
input 0-10 V.
High-speed processing applications
On a base PLC or peer PLC, each of the first 6 inputs (%I0.0
to %I0.5) can be assigned to the latching function after
configuration. This function is used to take account of input
pulses with short durations, 100
μ
s minimum.
Nano PLCs include standard functions which are easy to
set up and can be used for adaptation to control systems
requiring counting capacity or short response times :
i
Fast counter (maximum frequency 10 kHz)
i
Fast up/down counter (maximum frequency 1 kHz)
i
Frequency meter (maximum frequency 10 kHz)
Sensors which are used on the up/down counter inputs
(%I0.0 and %I0.3) must have solid state outputs.
2 reflex outputs (%Q0.1 and %Q0.2) are controlled directly
by the fast counter (without waiting for outputs to be
updated at the end of the scan) according to a matrix
predefined during configuration.
Pulse outputs
After configuration, the first output %Q0.0 (if it is a transistor
output) of the Nano PLC can be used with :
i
The
PWM
software function, as a pulse width modulation
output at a predefined frequency of up to 4.9 kHz
designed for use in applications with light or sound
intensity control (dimmer function).
i
The
PULSE
software function, as a pulse generator
output of up to 4.9 kHz designed for use for controlling
stepper motors.
