The program is discontinuous after Siemens 802dsl is changed to semi-closed loop

What you want to ask is why the program is discontinuous after Siemens 802dsl is changed to semi-closed loop? The reason for this is the following：

1, control logic error: Siemens 802dsl will introduce errors and defects when changing the structure and logic of closed-loop control system, resulting in discontinuous program execution. Check the control logic of the system to confirm whether there are errors and logical contradictions.

2. Data transmission and sampling: There are anomalies and errors in the signal acquisition, transmission and processing of Siemens 802dsl, which leads to discontinuous program execution. Check the data transmission channel, sensor sampling and signal processing process to ensure the accuracy and continuity of data.
