Product details

Network interface for MELSECNET/H rings

The Q80BD-J71LP21-25 is a PCI half-size interface board that connects a MELSEC Q-series programmable controller to a MELSECNET/H fiber-optic token-ring network. It communicates at 25 Mbps or 10 Mbps, with a double-loop transmission path for redundancy. Link capacity: LB 16384 points (2 Kbytes) and LW 16384 points (32 Kbytes) in extended mode. Fiber cable choices vary maximum inter-station distance: SI cable reaches 200 m at 25 Mbps, 500 m at 10 Mbps; H-PCF cable reaches 400 m / 1 km; broadband H-PCF and QSI cables go up to 1 km.

The module occupies one PCI slot and draws 0.46 A from the 5 V rail. It is rated for pollution degree 2 or less, overvoltage category II, and operation in non-corrosive atmospheres from 0 to 55 °C.

Frequently asked questions

What are the LB and LW capacities of this board?

In MELSECNET/H extended mode, LB is 16384 points (2 Kbytes) and LW is 16384 points (32 Kbytes). In MELSECNET/10 mode, both are halved to 8192 points.

What communication speed and method does it use?

It supports 25 Mbps and 10 Mbps via a token-passing ring method (HDLC-compliant frames). The transmission path is a double-loop fiber optic configuration for fault tolerance.
