FUNCTIONS
This chapter describes the details on the functions that can be used in the flexible high-speed I/O control module and their
setting methods.
1.1

Modes

The flexible high-speed I/O control module has the normal operation mode and inter-module synchronous mode. Change the
mode according to the function used.
Normal operation mode
This mode is for performing the hardware logic control.
Inter-module synchronous mode
This mode is for synchronizing the control timings of various functions of multiple modules according to the inter-module
synchronization cycle.
Mode transitions
The mode is determined depending on whether the flexible high-speed I/O control module is selected for a synchronization
target module in GX Works3 after the power-on or the CPU module is reset.

Update timings of the X/Y signals and Hardware logic area
The update timings of the X/Y signals and Hardware logic area (Un\G1000 to Un\G1099) differ depending on the mode. The
following table lists the update timing in each mode.
