T-link Network Features and Performance

The FUJI NC1H-TL1 functions as a T-link master or slave communication interface. Specifically, the 1 Mbps transmission rate ensures deterministic data exchange for critical I/O. In addition, the bus topology supports daisy-chain wiring for simple installation. Moreover, this card handles up to 64 nodes on a single network segment. Consequently, it provides fast and reliable communication for distributed I/O applications.

Energy Storage and Network Stability

This communication card stores energy using four onboard capacitors for power filtering. Specifically, two electrolytic capacitors smooth the 5 VDC supply for stable ASIC operation. In addition, two tantalum capacitors provide high-frequency noise suppression for the transceiver. Furthermore, these capacitors maintain network communication during brief power interruptions. Therefore, the FUJI NC1H-TL1 ensures uninterrupted data exchange on the T-link bus.

Configuration and Diagnostic Features

Four LED indicators provide operational status at a glance on this card. First, a green Power LED lights when the 5 VDC backplane supply is present. Second, a green Link Active LED illuminates when the cable connection is good. Third, a yellow Data Exchange LED flashes during network communication. Finally, a red Fault LED indicates hardware errors or bus cable breaks. Thus, you can diagnose network issues instantly without external tools.

Installation and Network Wiring

This communication card requires external bus termination at both ends of the T-link network. For instance, you must install active terminators on the first and last devices. In addition, use shielded twisted-pair cables for the T-link bus connection. Moreover, the card fits into any standard FUJI PLC rack slot. Therefore, this module integrates seamlessly into existing T-link installations.
