    Getting started with LOGO! The LOGO! system offers you many solutions such as for small domestic installations, simple automation tasks, and even complex engineering tasks involving its integration into a bus system (e.g. communication module AS inter- face). Note LOGO! Basic may only be equipped with expansion mod- ules of the same voltage class.

  • Page 311: B Determining The Cycle Time

    B 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 read- ing out of the outputs. The cycle time is the time required to execute a circuit program once in full.
