The invention discloses a programming method for batch processing of analog input signals based on a SIEMENS PLC controller. The programming method comprises the following steps: creating a user-defined PLC data type in a TIA Portal project tree; creating a data block, and establishing an array in the data block by taking a PLC data type as an element type; creating a function block, declaring a one-dimensional array of which form parameters are PLC data types in an interface area of the function block, and declaring a loop index variable, an intermediate conversion variable and an alarm temporary storage variable in a temporary variable area of the function block; executing cyclic batch processing logic in a program area of the function block; and calling the function block in the main program, and transmitting an array in the data block as an actual parameter through a pointer so as to complete batch processing of all analog input signals. The program structure is simple and clear, signal information is easy to search for field system maintenance personnel, the fault processing time is shortened, the system maintenance efficiency is improved, and the effect is remarkable.

The present disclosure provides a memory device and an operating method thereof. The operation method comprises the following steps of: receiving a writer mode instruction to operate the memory device to carry out data loading and programming parallel operation through system control logic; receiving and writing a plurality of word data to the memory buffer through the system control logic during a data loading period of the data loading and programming parallel operation; and reading the word data from the memory buffer and programming the word data to the memory array during a data programming period of the data loading and programming parallel operation, in which the data programming period and the data loading period are partially overlapped. The memory device and the operating method thereof can effectively reduce the time of system code programming.
