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 210
Special relay list, Page 225 Special registers list.
Starting/stopping high-speed counter measurement
High-speed counters cannot count by setting the parameter alone.
The HIOEN/DHIOEN instruction is required to start/stop the count.
For the HIOEN/DHIOEN instruction, refer to MELSEC iQ-F FX5 Programming Manual (Instructions, Standard Functions/
Function Blocks).
Read/write of current value of high-speed counter
The current value of the high-speed counter is stored in a special register for each channel. You can check current value by
monitoring the value. The value may however differ from the actual value because the special register is updated during END
processing.
You can read the latest value using the HCMOV/DHCMOV instruction.
For details concerning specials registers for high-speed counters, refer to Page 225 Special registers list.
For information for the HCMOV/DHCMOV instruction, refer to MELSEC iQ-F FX5 Programming Manual (Instructions,
Standard Functions/Function Blocks).
