FBM216 Module

During these two phases, even if the input state and data change, the status 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 flexible in application 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; when using a dual optical port chain network, it enables multi-segment Profibus DP bus connections (up to 200 segments) on the optical fiber bus. At the same time, this product uses dual optical ports to achieve dual-fiber ring network redundancy. When an optical fiber fault occurs, the system will rebuild the network link within 10ms to ensure normal system communication and achieve self-healing protection for signal transmission. Once the network fault is resolved, the system will automatically recover. This series of products uses the company's self-developed proprietary ring network protocol, Ci-ring, which requires no setup, no root node, and quickly completes network ring formation and de-ring functions. The products are plug-and-play, require no configuration, and greatly simplify the installation and debugging process for users.
