The program of step 3 and step 4 is as below:
C204 K10
X0
HA K1M1204 MOVP
DCNT
In O100 main program, design the 2
nd
set of high speed counter with both A/B phase counting mode and reset
function by setting K1M1024 = HA, i.e. b0/b1 = K2 and b3(M1207) = 1. When the instructions execute, C204 will start
the counting. If the reset signal input X11- is triggered, the value in C204 will be reset immediately.
Function Group:
High Speed Timing
Number:
M1200/C201, M1204/C205, M1208/C209, M1212/C213, M1216/C217, M1220/C221

b0 = 0: Normal mode.
The timing interval is from the rising edge
to the falling edge.
b0 = 1: Cycle mode.
The timing interval is from one rising

Example 1: Use the 3
rd
set of timer and set up the timing mode as Normal mode:
1. In O100 main program, design the 3
rd
set of high speed timer with normal timing mode by setting K1M1208 = K4,
i.e. b0=0, b2 = 1.
2. Execute the program and C208 will start to time the interval from rising edge to falling edge of the start signal X12.
The timed interval will be stored in C209 with the timer resolution 0.01us as the timing diagram below:
