Omron V460-H User Manual page 414

The timing signal indicating when the output data is stored in PLC memory varies depending on the selected
assembly.
• When using the Small (100) assembly, there is no applicable data output timing signal.
• When using the Big (101) assembly, the timing of data output is when the Device Status - In Read Cycle bit
changes from ON to OFF.
• When MXL/SLC (102) or a later assembly is selected, Output is at the timing when the Data Status Ready
bit of Device Status turns ON.
