19  BUILT-IN I/O FUNCTION

19.1  High-speed Counter Function

High-speed counter parameters are explained below.
High-speed counter parameters are set by GX Works3.

High-speed counter settings, high-speed comparison table, multiple point high-speed comparison table setting and input 
response time are set by parameters.
The primary items that can be set by parameters are as follows.
 • Basic settings
 • High-speed comparison table setting
 • Multiple point output high-speed table setting
 • Input response time setting

High-speed counter parameter setting method is explained below.
For parameter setting of each operation, refer to the following.
 • For high-speed counters (normal mode), refer to Page 124 High-speed counter (normal mode).
 • For high-speed counter (pulse density measurement mode), refer to Page 126 High-speed counter (pulse density 

 • For high-speed counter (rotational speed measurement mode), refer to Page 129 High-speed counter (rotational 

 • For high-speed comparison table, refer to Page 132 High-speed comparison table.
 • For multiple point output, high-speed comparison tables, refer to Page 134 Multiple point output, high-speed 

 • For input response time, refer to Page 191 General-purpose Input Functions.

Parameters are enabled when the CPU module is powered ON or after a reset. In addition, operations 
different from the parameter settings are possible by transferring values to special relays and special registers 
while changing these values in the program.
For details concerning special relays and specials registers for high-speed counters, refer to Page 137 
Special relay list, Page 148 Special registers list.
