MELSEC Series CC-Link Cable Length Specification Change Technical Bulletin

This technical bulletin details specification changes for MELSEC series CC-Link products, specifically regarding Ver.1.10-compatible CC-Link dedicated cable length limits when transmission speed is 10Mbps and total cable length exceeds 80m. The update requires that the total length of station-to-station cables connecting 10 consecutive stations be 10m or longer, or alternatively recommends reducing transmission speed to 5Mbps or less, or using a CC-Link system repeater (T-branch) module (AJ65SBT-RPT) to separate the system into IN-side and OUT-side segments each under 80m.
