Title: Inputs scan time..
Post by: shyampras on January 02, 2007, 10:46:20 AM

Hi,

What is the minimum (ON->OFF or OFF->ON) time required for the inputs to be recognised by the PLCs of E10+ series.

It depend on the program length plus I/O scan time. E10+ logic scan time is about 20 microsecond per step. For 200 step program, the scan time is about  4ms. I/O scan time is less than 1ms. So total scan time is less than 5ms. The input pulse must be longer than the total scan time in order to be guaranteed to recognize.
