Hello dchartier, Thank you for responding. Please have a look on the Modbus specification of Elster Instromet Q.Sonic device. As I said earlier, I can not acces the float values on this device. Thanks in advance AttachmentInstomet_Modbus.pdf (913 Downloads) |

Hello Scott; I really wish I could have a look at the manual you suggest. But the search page you point to(once I corrected "mobus" to "modbus") returns an empty search summary; looking for the part number of the driver in the A&D Mall gives no response either. And the Siemens IT group (who develop non-standard drivers for A&D CPs) do not show anything on a Modbus ASCII driver. Even google gives up the ghost on this issue. Is this a third-party software package perhaps? Or do you have other info we could use to locate this product in Siemens' world? I have always been aware of the Modbus RTU drivers for Siemens, but never saw anything on Modbus ASCII; I'm just curious, of course. Just wanted to expand my awareness of communication channels available with S7 PLCs. Regards, Daniel Chartier |

I have attached the PDF file for the ASCII Master documentation. I have ried a search in the A&D mall and can't find it. That is no surprise. The right hand not knowing what the left hand is doing. If you do a search in service & support web site you will find the manual and the driver to load into Step 7. It took a long time convincing them this would be something they should develop. This site gives you the drivers. http://support.automation.siemens.com/WW/llisapi.dll?query=Modbus%20ASCII%20driver&func=cslib.cssearch&content=skm%2Fmain.asp&lang=en&siteid=cseus&objaction=cssearch&searchinprim=&nodeid99=&x=0&y=0 If you have any other questions please ask.
