4.8 - Signal Diagram of Progressive Counter (Example at I/O 1)
When configuring a digital input as a progressive counter the e.bloxx constantly monitor the digital input for a signal
variation. If a negative signal edge (1 -> 0) occurs at the input, the current result is increased by 1.
The range of values of the counter is from approx. -2,1 billion up to +2,1 billion (32 bit). The values can be reset to zero
via the bus or via a digital input of the e.bloxx.
The progressive counter is possible with the inputs (I/O 1 ... I/O 4). The maximal counting frequency is 400 kHz.
Notice:
After a voltage cut-off all counters are reset to zero.
