Hi, My first post so please be understanding! I have 12 Danfoss VLT 6000 series drives on one of my sites for the control of dry air cooler fans in a condenser water circuit. Communication is currently via the I/O terminals on the drive however I have been looking at changing this to Modbus communication. I weighed up Profibus and DeviceNet however dismissed them mainly due to the need to purchase additional interfaces for the drives. I have been looking at the MVI46-MCM Prosoft module for this application and am wondering if anyone has used this module specifically for communication with Danfoss drives and if so could they share their experiences? Any general feedback on this module would also be much appreciated. If this is successful I would be aiming at utilising this strategy across the entire site. Phil
