Performance and Functions
CS1W-DRM21-V1
Features
• Allows control of up to 32,000 points (2,000 words) per master, and ensures a high degree of simultaneity between data.
• Can be used as both a master and a slave at the same time.
• Equipped with settings and monitor functions aimed at improving both design and startup efficiency. Achieve maximum performance by using
in combination with a Configurator.
• Files of master and slave settings can be uploaded and downloaded using memory cards, allowing effective debugging and easier setup.
