Monitoring of PMT dark noise in neutrino detector BOREXINO is a procedure that
indicates a condition of the detector. Based on CAN industrial network, top level DeviceNet protocol and WEB visualization, the dark noise monitoring system was created. The system process 224 channels for the internal detector and 256 channels for the external muon veto. The system is composed as a set of controllers, converting the PMT signals to frequency and transmitting them over the CAN network. The software is the stack of the DeviceNet protocols, providing the data collecting and transporting. Server-side scripts build web pages of user interface and graphical visualization of data.
