1.6.4 Digital Input Block (Digital Inputs)

The Blocks of the digital inputs allow to turn a signal available on the terminal strip into an internal signal. As
described before, the output of the Blocks is included in the lists for the selection of the different sources (src). The
Block function allows to invert the signal on the terminal strip.
For example, if the potential available on the terminal strip is +24V, and the inversion is disabled (not inverted)
the input state is 1 (one), standard configuration; if the inversion is enabled (inversion) the input state is 0 (null).
The Drive is supplied with 8 standard digital programmable inputs, referred as Std. The Drive ENABLE is
set on the Digital input 0; such condition can not be changed as it is performed via the hardware. Its function,
anyway, can be combined with a command signal in the sources of the other Blocks. For example, with the
Drive Enable it is possible to set at zero the Ramp output. In the list of the control signals for the Ramp control
Block from the Ramp funct src source, it is possible to connect to Ramp input = 0 the Digital Input 0 Enable
mon (the Drive enable set on Digital input 0).
During the Drive enabling phase, therefore, by making the ENABLE active, the Ramp output is set at zero. With
the expansion cards it is possible to obtain 12 expanded digital programmable inputs, referred as Exp with a
"X" suffix.
