Technical support / Can use 10KHz square pulse for intr input?
« on: June 23, 2002, 05:23:44 PM »
I have a question that relates to time period used by instructions of tmx100. How long is a TBASIC instruction?
My problem is scan 20 digital input in 10ms to realize the edge from OFF to ON of each input (like a custom counter)
Because the timers of m-series PLC only support to 0.01s resolution so I wonder that if I can use the PWM to creat a 10KHz square pulse and feed into an interupt input so that we can have a new timer with resolution of 0.1ms.
thanks for any advice.
