Hello Duris_I and William_B I have attached some pictures of the program running . As you may see, the COMM_Load runs with no error. The Master is still giving me the 8180 (invalid port ID or error with Comm_load instruction). I also included a picture of the CM1241 rs232 comm module, as you can see the LED lights for Tx and Rx dont blink at all while the program is running. Regarding the hardware as William_B suggest, I made the Null modem connections shown in picture. But I am still getting the error. I am not sure whether is my code that is poorly written or maybe the CM1241 it self. Are there programs written to test the CM1241? I want to make sure is functioning properly. Note: I am running the code I poster previously Thanks again for the support Gentlemen Attachmentmodbus_Error.pdf (487 Downloads) |

Hi. Sad.. it is sad to hear that the users' forum is not of help for your case. I am sorry about that. I suggest you take the next step. Come in contact with the official Siemens Support: https://support.industry.siemens.com/my/ww/en/requests#requests You will fill out some information and have the opportunity to state your problem. Make sure you include the hardware part numbers and the software versions and licensing you use. The first response from Siemens Support will quote pieces from the manual. The first response is rarely helpful to those of us who has done their homework. There is no way to bypass this first response. Be respectful and reply.. you can add your program for them with this reply. On average Siemens Support is better than what I have seen from others. If all goes well, you should have an answer in a few days. I ask you to return to the users' forum and inform us what the findings were. Good luck. w |

Agree with William, but let me say 'sad' also, because still don't know answer about COM settings on PC side application from you Ygor, also if you really had .DONE status ON checked, not depended that Status 16#0000. If you really didn't execute that MB_LOAD instruction, you still probably have 16#0000. Sry, but this is simply waste of time, we simply can't again and again ask and answers aren't here. Also if we take your TIA version, you didn't specify what kind of SP or updates you have, or not? Good luck. Last addition: look at that pdf, maybe this can be also helpful to you. modbusRTU with Delta Temp controller |
