Zaakceptowana odpowiedźI suggest you check the following items:
Is the communication panel cable reliably connected?
2. Hardware malfunction, communication chip damage (possibly on the motherboard or panel side)
3. The memory file of the motherboard is damaged, and the system cannot find the correct data, resulting in this prompt. Exclude by formatting and re downloading









I have resolved the issue caused by the failure to connect the numerical multi controller and HMI. Thank you
