FASTBUS Communication
FASTBUS provides a communication link between distributed substations. The master and slave module configurations support the exchange of signals across the system. Meanwhile, fiber-optic transmission allows communication over distances of up to 2,000 m using multimode cable.
The system supports up to 15 distributed substations. Therefore, the number of connected stations is an important consideration when selecting the communication configuration.
Fiber-Optic Connection Options
The connection technology offers two options: a robust Harting PushPull connector or an LC patch cable. In addition, master modules can feature one or two FO interfaces, depending on the required configuration.
The minimal signal delay supports communication between distributed system components. ColdClimate models are also available for installations requiring that product variant.
