Examples of Physical Inputs:
Digital Input Analog Input
9.1.1. Analog I/O
Concerning Analog I/O, some
settings are available:
Type:
depending on the model of
TB
OX
LT2
there may have different types of signal available (1..5V;
4..20mA; 0..10V, ...)
By default, Analog Inputs are configured as 0..10V inputs, to prevent damaging the
hardware if it is cabled before it is programmed.
4..20mA input stage is not protected against over voltage.
Scaling: the I/O can be scaled to real value by defining a MIN (corresponding to the smallest signal)
and a MAX (corresponding to the highest signal). The resolution defines the number of steps
of the scale (MAX – MIN / RESOLUTION).
