Hi
I am fairly new to PLC programming and I am self learning. I have written a simple program to detect and store the RPM and ultimately the frequency, of a conveyor in memory for use in the process later on.
but when i simulate the program the maths doesnt seem to work. I know the simulator doesnt simulate the SPD function so I wrote and integer to D0 memory location so the maths could function, but nothing happens I dont see any integers stored in any other memory locations.
I have attached a screen shot of my ladder, i am using a Mitsubishi FX1S and GX Works 2
I guess im missing something quite simple
