Note
CSV tags are used by SCADA software. The CSV tags consist of tag
numbers set for each function block, tag ITEMs corresponding to the function
block ITEMs, and the I/O memory address for each ITEM in the CPU Unit.
CSV tags are created using the CX-Process Tool. A CSV tag file can be
imported to an OPC server, tag numbers and tag ITEMS can be specified
from RS View or other SCADA software on the OPC server, and then the
data can be written to the Loop Control Unit.
