I set the MI 12 to 500 and it worked fine for 1000 Hz, then i set MI to 10 kHz and it went well but the voltage decreased from +24 V to +5 V, after that i tried to set MI 20 kHz and it stuck at 10 kHz.
Which is the highest frequency for these PLC's outputs ? (i assume is 1,500 Hz because it's pnp)
i ask because i need to work in the range of 10 kHz to 50 kHz, Do i need to change the plc or this plc can work at this range?
