1)
When you switch on LOGO! 24CE/24CEo, LOGO! DM8 24 or LOGO! DM16 24, the CPU sends
signal 1 to the digital outputs for about 50 μs. Take this into account, especially when using
devices that react to short pulses.
2)
The maximum switching rate is only dependent on the switching program's cycle time.
