Normally a HART-module (AI with HART capabiltys) have a headvalue and most of the time some or more sidevalues that are not transfered in the normal Profibus DP telegram. I have found that it is possible to read this values with SFC59, but what Records have to be given up, where can i find for different measuring the values that are behind this head-value?

The Send commands dataset numberhave to be 10, 14, 18, 22, 26, 30 and 34 for the first channel (0), this are the actual values for the 4 predefined dynamic variables. Reading channel0 is done with the commands 12, 16, 20, 24, 28, 32 and 36 there you get back the information. Here you have to look if the reading is alout. The Send commands dataset numberhave to be 50, 54, 58, 62, 66, 70 and 74 for the second channel (1), this are the actual values for the 4 predefined dynamic variables. Reading channel 1 is done with the commands 52, 56, 60, 64, 68, 72 and 76 there you get back the information. Here you have to look if the reading is alout. The readback can be seen in the loadaddress + 9 in the first bit, for the 2nd channel it is loadaddress + 15 in the first bit. The data that is send have to be a array of 3 bytes, the data that have to be read have to be a array of 240 byte. The senddata have to be set with 40h, 3, 0 for the different channels and clients, the Record Number for SFC58 have to be the mentioned commands for the send above. The receivedata have to be for the Record Number for SFC59 always Ch to check if the command is written and the channel can be written or not. For reading the records you need the Record Numbers as mentioned above for the chaneel where you have written the data to.
	I hope that the answer will help, if you have still questions, don't hesitate to ask me. All the best, Late Never say never, think in solutions, not in trouble......
