  • Page 275: Determining The Cycle Time

    Determining the cycle time The program cycle is the complete execution of the circuit program, that is, primarily the reading in of the inputs, the processing of the circuit program and the subsequent reading out of the outputs. The cycle time is the time required to execute a circuit program once in full.

  • Page 276

    Determining the cycle time Explanation The inverted flag block changes its output signal at each program execution. Thus, one logic level (high or low) width is exactly equivalent to the length of one cycle. Hence, a period lasts 2 cycles. The threshold trigger indicates the ratio of periods per 2 seconds, which results in the ratio of cycles per second.

  • Page 277: Logo! Without Display ("logo! Pure")

    Creating a circuit program without operator panel There are two ways to create a circuit program for a LOGO! without display: ● You create the circuit program with LOGO!Soft Comfort on your PC and then download it to LOGO!. ● You download the circuit program from a LOGO! memory card or combined memory/battery card (Page 227) to your LOGO! without display.

  • Page 278

    LOGO! is in RUN mode. Reading current data LOGO!Soft Comfort provides an online test for reading the current data of all functions while the system is in RUN. If your LOGO! without display holds a protected memory card or combined memory/battery card, you cannot read the current data unless you enter the correct password (Page 229) for the circuit program.
