3-4 Exchanging Data Using SCADA and Other Software
3-4-1 Exchanging Data Using SCADA, PTs, and Other Software
The Loop Controller can use CSV tags (tags can be created in CSV format
with the CX-Process Tool) to read/write the HMI data for the Control/Opera-
tion Block, External Control Block, and System Common Block from SCADA
software or from a PT (Programmable Terminal) through the HMI data area (in
the CPU Unit's specified EM area bank).
Note The User Link Table's tags can be handled as CSV tags just like the tags for
the HMI data. If the User Link Table's tags are in CSV format, it will be possi-
ble to read/write data in the CPU Unit's I/O memory areas from SCADA soft-
ware or a PT by specifying User Link Table tag names.
