This function shows the high-speed counter state. The high-speed counter flag shows the counter state under the CH special I/O state in the system variable (#L_ExIOSpCtrl). If the flag is ON, the counter is ON. If the flag is OFF, the counter is OFF. The watch bit will differ, depending on the CH to which you allocate the high-speed counter.
Special I/O state
If the start bit of the CH (0 bit) is 1, the output is ON. If it is 0, the output is OFF.
