T-LINK
• To use T-LINK communications on the V7 series, the communication interface unit
“CU-01” must be mounted. When the V7 series is equipped with the communication
interface unit CU-01, it becomes a T-LINK-ready device.
• The V7 series that supports T-LINK communications can perform long-distance
high-speed data transmission with the FUJI ELECTRIC’s PLC MICREX-F series.
• The V7 series updates the display when the read data (V7 series ← PLC) is changed.
The V7 series reads data from the PLC memory addresses that are allocated to the
items placed on the screen, such as lamp parts or counter parts. When switch data or
counter setting data on the V7 series should be written, the V7 series issues a write
command to the PLC and writes the output data to the PLC memory. These operations
are automatically performed on the V7 series and no special communication program is
required on the PLC side.
