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