CC-Link is used to connect the position indicator PLC with the gate controller PLC, or to connect the gate controller PLC with the data management PLC.
CC-Link is also used to connect the position indicator PLC and display device.
Results
-
- Reduce the processing time required for control
- The high-speed data link allows each function of the PLC to be distributed, shortening the time required for processing (scan time).
-
- A real time position indicator
- The high-speed data link allows the position indicator to be shown in real time on a display device.
-
- A real time monitor
- The high-speed data link allows the status/errors of the gate being controlled to be monitored with the GOT in real time.
-
- Reduce construction work hours
- Data transmission between the gate controller PLC and management PLC is achieved with less wiring, reducing the number of work hours required for construction.
