Development tools
It can be developed in various
tools
EMPLOYMENT OF THE SPECIAL
BIT
The special Bit tool. Said tool
consists of a discrete pulse
generator (logical "0" or logical
"1") and has the function of
energizing and de-energizing the
contact it represents with a fixed
time interval, which can be 1
second or 1 minute .
CALL FUNCTION
In what refers to the "Call
Function" tool, it helps to
structure and reduce our program,
since it encapsulates within a set
called Function a series of
instructions that perform a
specific task and this Function is
invoked whenever necessary, Its
implementation is explained in the
development of the following
example.
IDE4PLC
The IDE4PLC software is the
reference implementation of the
design proposed in “Software and
hardware design of a
programmable logic controller
(PLC) and its programming
environment”
• Possibility of offering a version
control system.
I / O Amount:
One of the most common
classifications of PLCs refers
directly to the number of inputs
and outputs (I / O or I / O) of a
PLC and tells us that a PLC is
considered a micro PLC when
they are less than 64 E / S, small
when they have less than 256 I /
O, medium when they have less
than 1024 I / O and large when
they have more than 1024 I / O.
