Fast digital signals are not detected in the controller
I have the prolem that, some signals form operator button are not detected in the controller, if the operator touch the button realy fast. I read the signals in a 10ms task in the controller. I can see the LED on the DI-Card but the signal is not reaching the controller. The IO-Card is connected to the controller over profibus.
Does anybody has similar problem whith fast digital signals?
Used Hardware secification:
Controller: AC800PEC (task 10ms)
Profibus: CI854 (Baudrate: 1.5M)
