Hi,

I have  an FM350-1. I have two pulses and I want to get the time between two successive edges of pulse 1 and pulse 2. it seems that it can give the time between two edges in one channel(DI). It is worth noting that I have this order code:

6ES7350-1AH02-0AE0

 The same problem, but I am looking for a solution, so I use different ideas. this leads to different problems.

the main problem is reading fast data with a slow plc cpu.

 Hello,

for me this is not correct, if you call your FC of the counter in OB35 with "5ms cycle time" even if a slow CPU 

should be able to do your job , try to do everything in this OB , if I remember correctly the FC0 requires approximately 0.85 ms to execute.

Please have a look the difference to call OB1 and OB3x
