3.6.8 Current tag data value area
The specified current tag data is stored.
This section explains how to display the specified tag data in the Current tag data value
area.
1 Set the tag number displayed in the No. of requested tag (Buffer memory address:
1290).
*1
2 Check that the tag number is stored in the No. of stored tag (Buffer memory address:
1291) and that the Update count (Buffer memory address: 1292) is incremented by
1.
*2
3 Check that the tag component values for the No. of components (Buffer memory
address: 1293) are stored in the Current tag data value (Buffer memory address:
1300 to 1811).
*3
*1 The tag numbers are the numbers beginning at 1 to 64 in the order set with MES Interface
Function Configuration Tool.
*2 If a value outside the range is set, the Current tag data value area is not updated.
*3 The Current tag data value area is updated each time the sampling is completed for the tag whose
number is set as the No. of requested tag (Buffer memory address: 1290).
(1) No. of requested tag (Buffer memory address: 1290)
Specify the tag number whose current value is displayed as the Current tag data value
(Buffer memory address: 1300 to 1811).
(2) No. of stored tag (Buffer memory address: 1291)
The tag No. displayed as the Current tag data value (Buffer memory address: 1300 to
1811) is stored.
