hello every one,

mehul from india.
reqd. help for solve prob. - S7-200 step7,
prob statement : how to convert digital pulse from proximity to rpm in ladder logic.
 
If you have one pulse for each rotation, just count how many pulses you get in 1 minute. That is RPM
 
an even easier way is to buy a digital to analogue converter and feed the result into the PLC via a 4-20mA signal.

Can get these that fit on your din rail.
