SIMATIC Library LPrintMark - Print Mark Acquisition with TO Measuring Input
Often in synchronous operations, the phase between the master axis and the slave axis is not the crucial factor. More the phase between the master axis and the product or rather the material that is transported via the slave axis is relevant.
Possible reasons for arising deviations between product and feeding axis are:
Slippage between product and axis
Wearing of rollers
Material faults or rather tolerances of the product
Intervention of machine operators
The blocks of the LPrintMark library are dedicated to support the user in acquiring these deviations or rather displacements by means of the technology object (TO) measuring input. The deviation is the calculated difference between an specified (expected) setpoint position and the measured value. The handling of the TO measuring input and the subsequent calculation of the present difference are the main features of the library blocks.
