The digital inputs are implemented as pnp which means that they are ac-
tive when voltage is applied to them. The inputs can be used to read buttons,
sensors or for communication with other PLC systems. The inputs are compliant
with all three types of digital inputs defined in IEC 61131-2 and EN 61131-2, which
means that they will work together with all types of digital outputs defined in the
same standards.
Technical specifications of the digital inputs are shown below.
