In your case better use trial version of this (just to try with S7-400 PLC PN).Download (register before go to download). Please post your result here. I used thia with CPU317-2 PN/DP and this works but I can't find information about S7-400 PLC. regards

I suppose that it works, but it doesn't exist an official release. In thenext version (at thebeginning of the next year) this product should be released for400 PN CPUsas well. Wüstenräuber

In this version the additional function codes 1, 2, 4, 5, 6 and 15 (conformance class 1) are supported and it is released for 400 PN CPUs as well. The current manual is downloadable here soon (if the date of change is newer than today ) and in this posting. Wüstenräuber Attachment Modbus TCP PN_CPU English.pdf (1979 Downloads)
