how do I count 0's and 1's

[Bernd R.]

After converting boolean true/false to (0,1) I'd like to count the number of ones during data acquisition or if better the number of trues before the conversion. Everything I tried accepted a different type of data (string or waveform instead of word)

How about feed the boolean to a case loop selector and set a counter in the loop?

An option can be to create an array with the boolean results, convert the whole array into 0's and 1's and then sum the array.

See the attached VI.

Thank you Enrique, that works good. Just that I need to know the count with every consecutive, incoming value, not after the loop is finished. So a count in real time.

Well, you could use the Add Array Elements primitive on the Numeric
palette on the array of 0 and 1.

OK, see if the attach VI is of help.
