Technical support / Re:Porbelm using internal timer
« on: July 10, 2006, 08:46:02 AM »
Hi,

Yes, I'm using high speed timer & setting for the solenoid on/off is 20ms.
What i want to know is the timer operate independently ? The output driver  for the solenoid off time will not affect by the scan time.
eg) long scan time > 20ms due to number of custom function enable within the PLC ladder program.

Technical support / Porbelm using internal timer
« on: July 09, 2006, 07:03:07 AM »
 Hi,

I am using the internal Timer to control the solenoid on/off timing. Found that the timing is not accurate when i measure it by scope. For example the timer setting is 20ms but the actual output can be vary 1 out of 10 times to 40 ms.
Can it be due to inconsistent scan time ? Program with number of custom function will cause irregular scan time ? How to over come the problem ?


regards.
