We are currently interfacing with a non siemens FlexIO device (gsd file is attached - zipped). ·Parts of data blocks ·Memory bits ·Process-image partition (part process image) for inputs ·Process-image partition (part process image) for outputs
It has been suggested in another forum that I use RD_DPARM (SFC 54). I have tried this but cannot get the SFC to run without error (the errori get is 0x80D2 which eqautes to invalid LADDR). The LADDR I specified was the output address (546 [0x222]) shown in Q address field for the device (see attached pictures). I can also see an diagnostic address (0x3FFA), which I have tried, but that also gives the same error. So 2 questions. 1) Will RD_DPARMdo it for me? 2) If so, how do I get it to work. If not, how else can I read back the parameterisation data from the DP slave? AttachmentFieldMonitor.zip (483 Downloads) |

Hi, Normal you could read with SFC59 parameters and with SFC58 write parameters... But in the documentation of the I/O you are usingthey must describe this, so no Expert could give you the right answer. See the handbook System Software forS7-300/400 System andStandard Functionsfor more information about the SFC's. |
I hope that the answer will help, if you have still questions, don't hesitate to ask me. |
