Input refresh
■
Inputs on the expansion module are reflected in the Input (#I, #D and LEX).
The HG5G/4G/3G/2G-V also performs output refresh when input refreshing.
■ Input delay
There is a delay for reflecting the expansion module input to the Input (#I, #D and LEX).
The delay time is as follows.
Minimum: 5 milliseconds
Maximum: 5 milliseconds + the execution period
There will be maximum input delay if input is made to the expansion
module immediately after the input refresh ends. The processor waits
for the input refresh in the next scan before reflecting the input to the
Input (#I, #D and LEX).
■ I/O control
Executes the script that is set to Cyclic Script.
■ Output refresh
The Outputs (#Q, #D and LEY) are outputted to the expansion module.
