4.2 Digital Inputs
The Digital Inputs have software-parameterizable threshold voltages. The
voltage levels can be chosen between:
 CMOS/TTL compatible or
 standard industrial level according to IEC 61131-2 Type 1.
This can be done via the "internal supply mask" bits in the digital input section of
the FFS block of the Parameter Manager. The internal supply mask bits controls
the threshold relays and therefore they are also called internal supply relays. For
more information please see the F-FEM Parameter Manual and the block
diagram Fig. 14.
