My problems START/STOP inverter, change frequency inverter, read frequency, error inverter from HMI. I have read manual, settings all parameter need for communication Modbus. But i don't know holding register for start/stop. I've trial value 047F for address 40001, 400001, 40002, 400002, 40003, 400003, 40004, 400004, 40005, 400005 but i can't run inverter. When i trial 403020 ( This is parameter 302. If parameter=0 stop, = 7 start. But i think that it wrong address. Please help me for holding register address VLT 2800. Thanks! _________________ vz Back to top sask Junior 2 Joined: 16 Aug 2016 Posts: 24 Posted: 29/05/2017 09:22    Post subject: Re: MODBUS FOR S7 1200 venza wrote: Hi everyone I have plc s7 1200 (1214C-DC/DC/DC), module RS 485 communication vs DANFOSS VLT 2800 via MODBUS.

Registers are as Code: 50000 Input data: Frequency converter control word register (CTW).    ex: 047C hex = Start / 043C hex = Ramp stop    50010 Input data: Bus reference register (REF).       100% = 4000 hex / 16384 dec    ... ...                   50200 Output data: Frequency converter status word register (STW).                   50210 Output data: Frequency converter main actual value register (MAV).       Take a look a complete description [URL=https://userscloud.com/ioknlih6ypwh]DanfossFC102.rar - 1.0 MB[/URL] Back to top venza Junior Joined: 24 Nov 2015 Posts: 3 Posted: 30/05/2017 15:40    Post subject: Hi Sack! Thank You reply!. Danfoss FC102 i have finished operation good. But Danfoss VLT 2800 different vs FC 102. I have tried address 50000& 50010 with value 047C unsuccessful. _________________ vz Back to top sask Junior 2 Joined: 16 Aug 2016 Posts: 24 Posted: 30/05/2017 16:29    Post subject: venza wrote: Hi Sack!
