We are using a S7-200 and are writing in Microwin.To use the hsc counters we initialise the SMB47(hsc 1) at value F8. In our interrupt we write C0 and increase the preset value each time with 4.We do the same for the other direction but now we are writing -4; its working but we have a little time delay while we are counting. Is there anybody who knows this problem or is there anybody who can help??
