Mitsubishi's A3ACPUP21S3, an Optical Data Link Module from the A Series, enables comprehensive control and communication in complex systems. Utilizing GL-20/125 cables, this module supports up to 2048 I/O points, allowing extensive connectivity in various applications. The communication speed reaches 1.25 Mbps, suitable for rapid data exchange between devices.
The module employs a half-duplex bit serial method for communication, ensuring efficient data transfer between connected components. The allowable momentary power failure time is set at 20 milliseconds, maintaining system integrity during brief interruptions. The synchronous method used is the frame synchronous method, which guarantees precise timing in data transmission.
For effective transmission path management, the duplex loop method is utilized, enabling reliable communication over significant distances. The overall maximum loop distance is 10 kilometers (32,810 ft), with a station spacing of 2 kilometers (6,562 ft) between individual connections. This arrangement allows for a high degree of flexibility in system design and layout.
In terms of connectivity, the module allows for a maximum of 65 connected stations per loop, composed of one master station and up to 64 local or remote I/O stations, facilitating extensive operational capabilities. The demodulation method employed is the CMI method, ensuring accurate signal interpretation. Furthermore, the module conforms to HDLC standards for its transmission format, utilizing frame methods for data packets.
The A3ACPUP21S3 also includes Remote Access Service (RAS) functionalities, which provide a loopback function and diagnostic capabilities for troubleshooting and monitoring purposes. A 2-conductor optical connector plug (CA9003S) is included for seamless integration into existing systems.
