Hi all,
It's been a while, but I was working in another area, and not touching code...
I'm back... with troubles
I have a Signet 2536 square pulse flow meter connected directly to a Micrologix 1400.
I chose that PLC because of the HSC, although they are not needed. (The speed I'm sensing has a max input of 150Hz).
And my trouble is that I am not getting the inputs in the PLC.
I have connected the Signet with the 10ohm resistor, to the 24Vcc, and I am not reading the input in the PLC.
I checked another input with the same result.
I checked the Signet with an oscilloscope, and I am getting the signals from the instrument.
I checked the input of the PLC with 24Vcc directly and get it without problem...
Do anyone has any sugestion on what to test or what can the problem be?
Thanks in advance.
