1P 265 Sample Applications and Programming Aids13.1.2 Sample Program with Parameter InterchangeSample application for case b):1P 265 control of a subprocess with parameter interchange between 1P 265 and CPU.If data (such as preset values for timers, counters or simple bit information) is to be interchangedbetween 1P 265 and CPU, it must be linked into the 1P 265 user program as input parameters (CPUto IP) or output parameters (IP to CPU).Sample application: Synchronizing a paper feederProblem definitionOn an assembly line, a strip of paper and a strip of cardboard are transported next to one anotheron a conveyor belt in a continuous process. Prerequisite for high-quality postprocessing is thesynchronism of the two strips (the front edges of the strips must always be exactly aligned). Evenminor deviations require a transport adjustment.Figure 13-4. Process: Synchronizing a Paper FeederEWA 4NEB 812 6130-02a 13-7
