Description

Integrate host computer systems directly into industrial networks via a dedicated PCI slot. The Q80BD-J71LP21G interface board provides reliable connection capabilities for high-speed deterministic communications. Engineered specifically for MELSECNET/H network architectures, this module operates as either a control station or a normal station within an optical fiber loop network, facilitating seamless data exchange between PCs and PLCs.

Operating at a transmission rate of 10 Mbps, the interface board utilizes dual-loop optical fiber cabling to ensure physical path redundancy. If a cable break or station fault occurs, the network automatically initiates loopback operations to maintain communications. It features backward compatibility, supporting both MELSECNET/H extended modes and legacy MELSECNET/10 configurations to easily integrate into existing control topologies.

Features

Standard half-size PCI slot interface for integration into industrial computers.
Double-loop optical fiber transmission path for redundant, fault-tolerant network routing.
High-speed deterministic data exchange utilizing token ring access methodologies.
Supports the simultaneous installation of up to 4 interface boards per host computer.
Robust frame synchronization and NRZI coding with CRC error checking.

Applications

Automotive assembly line synchronization and telemetry monitoring.
Water treatment distribution networks and pump control systems.
Power generation plant supervisory control and data acquisition.
Redundant high-speed process automation environments.

Installation Guidelines

Slot Insertion: Align the interface board carefully with an empty PCI slot on the host industrial PC and secure the mounting bracket firmly to the chassis.
Electrostatic Protection: Handle the board using appropriate ESD wrist straps or grounded mats to protect sensitive CMOS components.
Fiber Care: Clean the optical fiber connection faces with certified optical cleaning tools prior to insertion. Respect the minimum bend radius of GI-50/125 cables during routing.
Driver Configuration: Ensure the appropriate Mitsubishi MELSECNET utility and board drivers are fully installed before running network diagnostics.

FAQ
