The Micro 4000NET web guide controller now interfaces with BST’s CLS Pro 600 laser-guided, digital line/edge sensor. The CLS Pro 600 precisely scans lines, print or web edges using a highly accurate, high-resolution CCD-color line chip. A high scan rate of 500 hertz allows the CLS Pro to recognize interrupted lines or poor line contrast, even at high speeds. The 4000NET controller uses the sensor’s reading to recalibrate the web guide system every four milliseconds. Using optional fieldbus adapters, the 4000NET controller easily interfaces with most popular fieldbus networks, including ControlNet, DeviceNet, Modbus Plus, Profibus-DP and Ethernet protocols. Discrete I/O interfacing is a standard feature.
