Today, the application requires that I use an S7-1500 instead of the S7-1200 and unfortunately there are problems. To read values from the PN/M-Bus LINK module in both cases I used RDREC (as in the manual) and in the case of the S7-1500 when trying to read there is an error and the block returns status 16#C080_B100. Can anyone help explain what this means?
