Function Group	High-speed Timer
Number	M1015, D1015
Contents:

1.When M1015 = ON, high-speed timer D1015 will be activated when the current scan proceeds to END instruction. The minimum resolution of D1015 is 100us.

2.The range of D1015 is 0~32,767. When it counts to 32,767, it will start from 0 again.

3.When M1015 = OFF, D1015 will stop timing immediately.

Example:

1.When X10 = ON, M1015 = ON to start high-speed timer and record the present value in D1015.

2.When X10 = OFF, M1015 = OFF. High-speed timer is disabled.
