You can also program it on yourcomputer with the easySoft 7 programming software program (this option can also beused for base devices without a display).For example, you can:l Connect N/O and N/C contacts in series and in parallell Connect output relays and markers.l Define outputs as coils, impulse relays, risingor falling edge-triggered relays or as latching relays.l ...You can use the function blocks to run arithmetic functions, compare values, count up,count down, etc. All the function blocks available are provided in a list → Section "Func-tion blocks", page 166If you wish to wire a easyE4 device via your PC, i.e. create a circuit diagram, use theeasySoft 7→ Section "Programming software easySoft 7", page 28.20 easyE4 11/18 MN050009 EN www.eaton.com
