The cycle is referred to as a scan cycle or scan. Under default conditions, all digital and analog I/O points are updated synchronously with the scan cycle using an internal memory area called the process image.

    PLC concepts made easy 4.2 Operating modes of the CPU This process provides consistent logic through the execution of the user instructions for a given cycle and prevents the flickering of physical output points that might change state multiple times in the process image output area. You can change the default behavior for a module by removing it from this automatic update of I/O.

    PLC concepts made easy 4.3 Memory areas, addressing and data types Memory areas, addressing and data types The CPU provides the following memory areas to store the user program, data, and configuration: ● Load memory is non-volatile storage for the user program, data and configuration. When a project is downloaded to the CPU, it is first stored in the Load memory area.
  • Page 34 PLC concepts made easy 4.3 Memory areas, addressing and data types Data types supported by S7-1200 Data types are used to specify both the size of a data element as well as how the data are to be interpreted. Each instruction parameter supports at least one data type, and some parameters support multiple data types.

  • Page 36 PLC concepts made easy 4.3 Memory areas, addressing and data types Each different memory location has a unique address. Your user program uses these addresses to access the information in the memory location. The figure shows how to access a bit (which is also called "byte.bit" addressing). In this example, the memory area and byte address (M = bit memory area, and 3 = byte 3) are followed by a period (".") to separate the bit address (bit 4).

    PLC concepts made easy 4.4 Execution of the user program Execution of the user program The CPU supports the following types of code blocks that allow you to create an efficient structure for your user program: ● An organization block (OB) is a code block that typically contains the main program logic. The OB responds to a specific event in the CPU and can interrupt the execution of the user program.
  • Page 38 PLC concepts made easy 4.4 Execution of the user program An OB within a priority group does not interrupt another OB within the same priority group. However, an event in priority group 2 will interrupt the execution of an OB in priority group 1, and an event in priority group 3 will interrupt the execution of any OB in either priority group 1 or 2.
