Jay Anthony Posted February 17, 2013 Report Posted February 17, 2013 This one stumped me for a while until I read the data sheet. "Use stand-alone with an EJ1C-EDUA-NFLK End Unit to connect RS-485 serially to MX2 AC Drives, E5?N Temperature Controllers, and other Modbus devices for a low cost gateway to PROFINET on Ethernet cable." Be sure to download all references found in the datasheet. EJ1N-HFU-ETN_DataSheet.pdf EJ1N-HFU-ETN_InstructionSheet.pdf
ChinthanaW Posted February 17, 2013 Author Report Posted February 17, 2013 Thank you Jay. I think it taking necessarily power from the end unit. - Chinthana
