Dear All How i can read a double word in 30000 series address in modbus communication in TIA V13 advance Runtime. Actually i am communicating with a Energy meter on Modicon Modbus RTU protolcol in TIA V13 advance. There are addresses in 30000 series .i.e. input registers. Now my issue is that the address which required single word length is communicating but those who required 2 word are not communicating. Kindly tell how i can use 2 words length in Input register series. Kindly check attachment for energy meter manual for reference. ------------------------------------------------------------------------------------------ AttachmentL&T Vega Multifunction meter.pdf (315 Downloads) |

What do you by "not communicating" exactly?
I also noted that some values are sent as 3 registers (48-bits). I have never, ever seen this before and I have no idea hoe they have been encoded as the manual fails to mention it. |
Programming today is the race between software engineers building bigger and better idiot proof programs, and the universe producing bigger and better idiots. |
