Posted 18 Sep 2021 Hello Everybody, I continued to work on project this morning but I seem to be plagued with the "PLC No Response" error. This error will only come up when I assign a PLC address to a particular object. I have followed the steps in the post(https://forums.mrplc.com/index.php?/topic/39885-nb-designer-hmi-plc-no-response-error-solved/) to try and clear the error but am having no luck. In the screenshot I have assigned the large "Start Process" as a bit button with the write address being W50.00. When the button is pressed it should trigger a bit in the PLC but this is when the error appears. During this test I am connected to the PLC and in run mode with the PLC and HMI address assigned correctly. I have read and followed the section in the manual regarding "PLC No Response" but still no positive results. I just want to check that there is nothing I have done at a programmer end that could cause these issues. I am happy to provide files. Thanks, Ryan Share this post Link to post Share on other sites
Posted 20 Sep 2021 What communication method are you using? Ethernet or Serial? sharing both the PLC and HMI will be helpful Share this post Link to post Share on other sites

Keep in mind this code is still a work in progress so not everything will be assigned correctly. Tray Dryer.cxp Tray Dryer PROLEC.nbp Share this post Link to post Share on other sites
Posted 21 Sep 2021 So the NB designer needs a whole bunch of files to go with it. I can't open just the .nbp file. However - I think I see the problem in the PLC. PLC Settings -> Built-in Ethernet -> FINS Node No. : This should be the last octet of your IP ( 1 in your case) In the NB since I can't open the project I'll just show you the settings(see attached). Your IPs may vary but remember the last octet of the IP is the station number. Share this post Link to post Share on other sites
