+ With S7-1200/S7-1500, how do you measure the time of a program section or the complete program cycle at runtime? (2014-02-11) [87668055]
Description Measuring runtimes with the 'RUNTIME' instruction Using the 'RUNTIME' instruction you measure the runtime of the complete program, single blocks or the command sequences. You can call this instruction in SCL (S7-1200/S7-1500) and in STL (S7-1500). The following example (Fig. 01) shows the calculation of the runtime of the 'TimeDelay' [FC2] function for an S7-1500. The call of the first instruction (CALL RUNTIME) sets the starting point for measuring runtime ...
