11. BMX EHC 0800 Functionalities BMX EHC 0800 Module Operation in One Shot Counter Mode At a Glance Using the one shot counter mode allows you to quantify a group of parts Basic Principle In this mode activating the synchronization function starts the counter which starting from a value defined by the user in the adjust screen preset value decreases with every pulse applied to the IN A input until it reaches the value O Downcounting is made possible when the enable function is activated The counting register is thus updated every 5 ms 74 100000000318 07 2012 BMX EHC 0800 Functionalities Operation IN A input pulses IN AUX input valid syncbit force enablebit Counter value User defined value preset value Operation of the counter The trend diagram illustrates the one shot counter mode process F i dol In the trend diagram above we can see that the counter starts downcounting at the IN AUX input s rising edge The counter loads the value defined by the user and decrements the counting register with every pulse applied to the IN A input When the register is set to O the counter awaits a new signal from the IN AUX input The IN A input pulses have no effect on the register value as long as the counter is set to 0 The force enable command must be at the high level during the counti
