I don’t think it’s the values in DB6 which are the source of the problem, I think it’s the sheer size of the load memory taken by FB6/DB6 that’s causing the problem. Once I delete FB6/DB6 from ONLINE and re-download them, CPU seems to be suddenly relieved from whatever burden it was suffering from and returns to normal operation after a restart. I am dealing with about 8 more CPU 412-1DP with exactly the same program yet half the size (fewer PID controllers). They don’t have this particular problem. Scan cycle as shown in the attachment is between 7 and 11 ms. Work memory is about 91 percent after compressing (almost no change). There is problem with firmware version which I need to correct in the hardware (ironically when I once generated Sdata for Ver 3.1 the CPU went into stop and could not be restarted under any condition, thus I downloaded the old Sdata).

Hello,
Even if you succeed in opening this block, it wouldn't help you, without the source i think it's verry hard to read. There is no need to open it, the block is well documentated in the Help and manuals So put your energy in reading instead of trying to open protected blocks. Regards, Marcjan |
Problem solved? |
