9. easyE4 inside9.7 NET network9.7 NET networkThe NET functionality via Ethernet was created in order to simplify communicationsbetween easyE4 base devices while simultaneously ensuring that it would be possibleto import existing easy800 projects.A NET group can be made up of up to eight easyE4 base devices. Within the group, theeasyE4 base devices can communicate with each other. If, however, you want devicesto be able to communicate across groups, you will need to use a coordinator devicethat allows the easyE4 base devices from the various groups to communicate witheach other via Modbus.Ten NET groups (groups 1 through 10) can be run on a single Ethernet network at onetime (this is the equivalent of 80 easyE4 base devices).Ethernet network↑ ↑ ↑ ↑ ↑ ↑ ↑Module Module Module Stations… Module Module ModuleNET-ID 1 NET-ID… NET-ID 8 NET-ID… NET-ID 1 NET-ID… NET-ID 8NET group 1 NET group… NET group 10The following list shows the operands that can be used within a group by every device:l (n = NET-ID 1 .. 8)l n SN 01 - 32 [Bit]l n RN 01 - 32 [Bit]l PT 01 - 32 (PUT) [double word]l GT 01 – 32 (GET) double word]l n N 01 - 512[ Bit]l n NB 01 - 64 [Byte]l n NW 01 - 32 [Byte]l n ND 01 - 16 [double word]l Synchronize clock (settings)ExamplesStation 1 sending a bit to station 2NET-ID1 NET-ID 22 SN 15 ￫ 1 RN 015Station 3 sending a double word to station 8 via PT16NET-ID1 NET-ID 2PT16 ￫ GT 01ParameterNET-ID 1PT 16easyE4 11/18 MN050009 EN www.eaton.com 513
