This section explains the input (X) loading and output (Y) writing timings of the C
Controller module.
(1) Input (X) loading timing
The C Controller module executes input (X) loading when the bus interface function
(such as the QBF_X_In_BitEx function) is executed in the user program.
(2) Output (Y) writing timing
The C Controller module executes writing to output (Y) when the bus interface
function (such as the QBF_Y_Out_BitEx function) is executed in the user program.
Remark
1. Refer to Section 10.2 for details of the bus interface functions.
2. Refer to Appendix 1 for the processing times of the bus interface functions.
