2.5 Connecting the inputs
The inputs of the easy800 devices switch electronically. Once you have
connected a contact via an input terminal, you can reuse it as a contact in
your circuit diagram as often as you like.
Connect the contacts, for example pushbuttons or switches, to the input
terminals of the easy800 device. This does not apply to EASY802-DC-SWD
as it does not have any input terminals. easy800-SWD devices primarily use
SmartWire-DT for wiring.

When using special function blocks, certain inputs are permanently assigned
to these function blocks and cannot be used for any other purpose. The
relevant function block description describes which inputs are affected.
Example: With the “high-speed counter” function block, the device inputs
I1 - I4 are connected directly on one function block.
You can increase the number of inputs of the easy800 standard by using an
expansion unit. The inputs of the EASY4..-DC-.E and EASY6..-DC-.E digital
expansion units are detected by the easy800 standard automatically -
without any configuration.
The universal EASY4..-DC-ME expansion units allow you to process both
digital and analog values. The digital inputs of these expansion units are
detected by the easy800 standard automatically - without any configuration.
The analog inputs/outputs must normally be configured.
