E70 Series Instruction Manual
5.8 Data Sampling Screen
I - 323
(Note1) When "3" or "4" is set in "Start condition", be sure to set the address, the data, and the data mask. This applies
to "End condition" as well. If these are not set, sampling may not start.
When the same values are set in both "Start condition" and "End condition", sampling will not take a place.
(Note 2) When "1" is set in "Start condition"/"End condition", the common variable uses the floating decimal point type.
Thus, if the calculation results are used, an error will occur, and the value may not be recognized as "0"
because of its calculation error.
(Note 3) The variable data settings are validated immediately only from the program. These will not be validated
immediately with settings from the screen or an external input.
(Note 4) Even if "End condition" is satisfied, the subsequent flow will differ according to the value set in "Process type".
(This also applies when ending manually.)
(Note 5) If the "start condition" is set to "1", the "process form" needs to be set to "2: ring buffer valid".
Example of "End condition" by setting address
Setting
End condition : 3
Address : 12345678
Data : 00000100
Data mask : 0000FFFF
Meaning of setting
The trigger for sampling end turns ON when the results obtained by applying data mask
"0000FFFF" on the data of which address is "12345678" matches "00000100".
