3.6 Device-specific Settings3.6.5 Setting the Scan Times3-50 I/O ProcessingIf the high-speed scan time is set to at least 0.5 ms, the I/O service (I/O processing) of theMP2000 Optional Module will be performed every scan. If the high-speed scan time is set toless than 0.5 ms (0.125 ms or 0.250 ms), the I/O service (I/O processing) of the MP2000Optional Module will be performed at the filtered basic cycle of 0.5 ms. The following figuresshow the timing results for these settings. Example: High-speed Scan = 0.5 ms* The purpose of this system service register is to determine from a ladder program whether the MP2000option service is being scanned. Example: High-speed Scan = 0.250 ms* The purpose of this system service register is to determine from a ladder program whether the MP2000option service is being scanned.0.5 msReference issued at (3)Reference issued at (2)Reference issued at (1)System serviceregister SB000008 *MP2000 OptionalModuleBasic cycle (0.5 ms)High-speed scan0.25 ms0.5 ms Reference issued at (5)Reference issued at (3)Reference issued at (1)System serviceregister SB000008 *MP2000 OptionalModuleBasic cycle (0.5 ms)High-speed scan
