CHAPTER 1
HIGH-SPEED COUNTER MODULE
This chapter describes the operation, the application, and the features of the high-speed counter module.
The high-speed counter module is a remote device station of the CC-Link IE Field Network whose maximum counting
speed of input pulse is 8Mpps (with differential input and 4 multiples of 2 phases).
The module has two channels and functions including the preset/replace function by external input or input from a
master module, the latch counter function, counter function selection, external coincidence output by coincidence
detection.
The following illustration shows the operation overview of the high-speed counter module.

1) Pulses input to a high-speed counter module are counted.
2) The preset/replace function can be performed, counting can be paused, and a counter value can be
latched with an external control signal.
3) Status of the remote I/O signals, remote register, and remote buffer memory of a high-speed counter
module can be checked with the program.
Also, counting can be started/stopped; and the preset/replace function and the coincidence output
function can be performed.
4) The coincidence output signal can be output by the coincidence output function.
