Enabling and Disabling HSC0

I'm attempting to monitor the frequency of the pulse train in two ways: Using a high speed counter HSC0 to count pulses acros a set time period and also using an interrupt on each rising edge that compares to the time of the previous interrupt. HSC0 is set to interrupt 28 and the timer is on interrupt 0 as per the S7 manual. My question is this: The counter works fine, but interrupt 0 appears tonever be triggered even wheninterrupt 28 has been detached prior. In the attached code, T38 times 3 seconds then resets. At the end of each period, VD108 is compared to a set value which determines which measurment method to use. Currently if VD108 is <2000 then HSC0 counts correctly. If VD108 is >=2000,interrupt 0 is detached and interrupt 28 is attached. The interrupt subroutine runs a test code that toggles M2.6 with T32 connected simply to give an output. As the pulse train is relatively slow (200-300ms) and the maximum scan time is 3ms, I should be able to see M2.6 cycling and the timer running under program status correct?

It would be better to create a new post in the already existing thread and add your further information there. Best regards O_Moderator
