Hello gre_m; You should have a look at the following FAQ: http://support.automation.siemens.com/WW/view/en/11646774 The second part discusses SFC14/15 limits, whic seem to be 128 bytes (per call of SFC, you can doyour 240 bytes over 2 cycles). They also propose a different solution using process images, see if it helps. regards, Daniel Chartier |
