1: Enabled
Note 1. Data attributes and contact alarm tags are used mainly by the OPC Server.
2. The offset is stored when there are both write and read ITEM numbers in the
Loop Controller. If the CPU Unit's I/O memory address in the same for both
reading and writing, the offset will be 0. If they are different, the value of the
write address minus the read address will be stored.
3. Expanded scaling data can be exported only when using CX-Process Tool
version 4.0 or higher.
The relationship between LCU/LCB properties and CSV tag files for the SYS-
MAC OPC Server is shown in the following table.
LCU/LCB property
Contact alarm tags
Scaling upper limit
Scaling lower limit
DP position
Unit
Data range upper limit
Data range lower limit
Function block FP number
Block address
ITEM number
Pre-scaling upper limit
Pre-scaling lower limit
Note Can be changed only then outputting CSV tag information is selected when reg-
istering user link tables. For tags other than those for user link tables, default
values are set (range conversion upper limit: 10,000, lower limit: 0).
Setting range for ITEMs
User link table tags
R: Read, W: Write
Read and write are from the
viewpoint of the SCADA soft-
ware. If the tag is set for read-
ing from the CPU Unit (to the
Loop Controller), it will be
write data from the SCADA
software. If the tag is set for
writing to the CPU Unit (from
the Loop Controller), it will be
read data from the SCADA
software.
