Dear Joe The system has been in use for half a year. There are also links to VFD Ok, I will check the noise. Thanks to JOE for your support.

Hello everyone I also encountered the same problem (causing customers' troubles) Is the communication cable too long? Is it the power cord of the device or the power cable of the HMI? The environment is too noisy? Is there usually a decibel that regulates the use environment? I changed Porter? How do I change it? Is there any other way to improve?
