When the sampling time and values of devices from data start number 1 to end number 3 are copied to the
destination device as two items of data
Item Setting
Destination Device LDR 10
Starting Point Newest Data
Number of Data 2
Stored Order of Data From Oldest to Newest
Target Data
Sampling Time, Value of Device
Data No.: Start No. 1, End No. 3
When writing with the following settings, “Device range error” is displayed.
• Starting Point is 0 or a value larger than the amount of saved data
• Start No. is 0 or a value larger than Data No.
• End No. is 0 or a value larger than Data No.
• Start No. is a value larger than End No.
