Magelis HMI to Danfoss FC102 Modbus

Hi, I want to connect a Schneider Magelis HMIS5T to a Danfoss FC102 via Modbus to display some values and just having some issues with the addressing. The Vijeo software allows for the Modbus driver to use addressing as 40001 + the offset. So if I am looking at DC Bus voltage parameter 16-29 I would assume address would be 40001 + 1629 = 41630. I've also seen suggestions it should be 16.29*1000 + 40001 = 56291 but this takes it outside the range 40001-49999. I'm not too good on this sort of thing but any assistance would be appreciated.

All Modbus data is organized in coils and holding registers. You are correct with the address 41630.

Hi, I have managed to access read parameters okay using the drives PCD read / write configuration which is simple enough to do from the Magelis in Vijeo Designer. If you understand what I mean so far, then my next problem is finding out how to send a drive start command using Vijeo as the control word needs several bits of a 16 bit string as 1 (e.g. coil 2,3,4,5, 6 and 10) before the drive can start. I cant seem to find out how to write this sort of command using the Variable options available in Vijeo Designer. The drive is seen in Vijeo Designer as a Modbus RTU Equipment device. Thanks in advance for any tips.

count hex code of bits and send control word same way than you readed words from drive

Thanks for your help I worked it out. Command is an integer so needed to create the variable that way. To start the drive, needed to send a control word from the switch in decimal. Therefore needed to convert the binary bits to decimal. Anyway it works so happy!
