Foxboro FBM215

During these two phases, even if the input status and data change, the state and data of the corresponding units in the I/O image area remain unchanged. Therefore, if the input is a pulse signal, the width of this pulse signal must be greater than one scan cycle to ensure that the input can be read under any circumstances.

This product is highly flexible and can form various optical fiber networks. With its logically independent dual-bus electrical interface, it enables backup of electrical interfaces or single-device access to dual-redundant bus systems. When using a point-to-point network, it can connect two Profibus DP bus segments via optical fiber. In a dual optical port chain network, it supports multi-segment Profibus DP bus connections (up to 200 segments). Additionally, this product utilizes dual optical ports to achieve dual-fiber ring network redundancy. In the event of a fiber fault, the system will rebuild the network link within 10ms, ensuring normal communication and providing self-healing protection for signal transmission. Once the network fault is resolved, the system will automatically recover. This product series employs the company's self-developed proprietary ring network protocol, Ci-ring, which requires no configuration or root node, enabling rapid network ring formation and dissolution. The series is plug-and-play, requires no configuration, and greatly simplifies user installation and debugging processes.
