What's purpose of the FAST INPUT MODULE EL1202 | 2-channel digital input terminal 24 V DC, TON/TOFF 1 µs
If the maximum PLC Cycle is 50 µs and there is no option hardware interrupt.??https://www.eng-tips.com/threadminder.cfm?pid=791
I've been working more than 5 years with SIEMENS PLC-s...
I am calculating power factor from samples of voltage and current. Calculation is done by multiplying voltage and current samples. What Im struggling is sign. I have read it is possibleto determine sign with JK negative triggered flip flop method. I found how exactlly JK flip flop works but...
Thx guys on quick response. I will also think about more ideas too. Frequency is variable, I mean I am measuring it with PLL, It can be different than 60Hz.
I mean I should be able to measure at least from 20-75Hz
Hello guys. I got AI card which takes samples every 50micro sec. My PLC cycle is 1ms which means I get every ms array of 20samples. I am measuring 3 voltages and 3 currents. Phase values. My goal is to have correct and quick as possible measurement. I am measuring frequency with PLL method and...
