Hello! How to read data from the controller? When recording, an error appears with the code: 4

Hi! This library doesn't implement read feature, only write. If you want get data from controller using this driver, you have to implement the block MSG in controller to send data to host. Error code 4 means 'PathSegmentError'. Maybe the driver couldn't locate the tag/symbol in PLC. Or the array type or size are different.
