Prizm_Controls Posted February 27, 2016 Report Posted February 27, 2016 Good Morning All, I have a NOM 212 00 card that I plan on using to talk to 3 Multilin 369's that are Daisy Chained on a 2 wire 485 network. Obviously I will need a 232 to 485 converter as the NOM card Modbus port only utilizes RS 232. I am fairly new to the Modicon world but not to Modbus. I am basically after what function blocks in Proworx 32 a person would use to set up that port and pick and choose registers. Would it be as simple as an MSTR instruction? or what about the XMIT instruction? Any help would be appreciated! Quote
Quant Posted February 29, 2016 Report Posted February 29, 2016 Hello, in case you are using Modbus Port on NOM212 you have RS232 and you need to use RS232-RS485 converter for NOM. For serial connection to have to use XXMIT block, in HELP you will find working example. MBP_MSTR is only for Ethernet or Modbus+ communication. Quote
