WebFeb 9, 2007 · FISCO allows fieldbus to enter intrinsically-safe environments. Improvement, indeed, yet FISCO makes this incremental gain at the expense of operational limitations. … WebThe high-power trunk concept with Entity or FISCO devices: Connect the maximum number of devices to the same fieldbus trunk; and at the same time makeuse of maximum cable lengths. This concept utilizes standard power supplies such as the easy-to-install and configuration-free power hub.

WebThe FISCO and FNICO power supplies have a soft start feature to ensure the fieldbus segment starts up. For example for a segment with 16 x 15mA devices powered by a 9122-IS IIB FISCO power supply, the segment will normally require 240mA which is less than 265mA 9122-IS design current. WebThis Fieldbus coupling device is aptly labeled a segment protector, for it not only couples spurs to the main trunk of the Fieldbus segment, but it also guards against short-circuits in the spur cables and devices from interrupting communication on the rest of the segment. WebFieldbus requires proper termination. The bus terminators create the load that translates the fieldbus signal transmitted as a current change into a detected voltage on the cable. This accentuates the importance of proper and reliable bus termination, which plays an important role in system availability. framed perspective 汉化
