Hello Recently I changed machine from using IPC (VISControl) to using HMI Schneider HMIET6600 The machine is S7-300 CPU315-2DP. I have uploaded the project from the PLC. I have connected the PLC and HMI HMI can read the status of input and output and also DB. But when i try to change value of M70.0 from 0 to 1 using HMI or modify value Simatic manager. And then It flips back to origin value 0. Even though I have checked in the cross reference there is no Write.only Read. But when i try another address M150.0 which is not used in PLC. The HMI can change the value I tried to using DB address. it stills the same. Is there some sort of clear value of address even in the cross reference there is no Write? if anyone want to see the project here is attached Thank you for your help AttachmentCtn3_an.zip (116 Downloads) |
