Precautions when using FX3-compatible high-speed counters
Shown below are the precautions for using the FX3 compatible high-speed counter. For any other precautions, see the
precautions for each function.
• When the FX3 compatible function is valid, it is possible to specify the LC device in (s1) of the HSCS instruction/HSCR
precautions for each function.
• When the FX3 compatible function is valid, it is possible to specify the LC device in (s1) of the HSCS instruction/HSCR
instruction and (s) of the HSZ instruction. If an LC device that is not used as high-speed counter is specified, an error
occurs, and the HSCS instruction, the HSCR instruction, and the HSZ instruction do not operate.
occurs, and the HSCS instruction, the HSCR instruction, and the HSZ instruction do not operate.
• Set up the table with the CH number of the counter if the table number of the high-speed comparison table/the multi-point
output high-speed comparison table needs to be specified.
• To clear the current value of the LC device, use the DHCMOV instruction or the RST instruction to clear it.
• Use the latch setting to use LC35 to LC55 with the high-speed counter of the FX3 compatible function.
• The reset coil of the LC device is cleared when the power is set from OFF to ON.
• Use the latch setting to use LC35 to LC55 with the high-speed counter of the FX3 compatible function.
• The reset coil of the LC device is cleared when the power is set from OFF to ON.
