Section 3 1MRK 502 043-UUS B Analog inputs Section 3 Analog inputs Introduction Analog input channels are already configured inside the IED. However the IED has to be set properly to get correct measurement results and correct protection operations. For power measuring and all directional and differential functions the directions of the input currents must be defined properly.

The output is operated by a "Object 12" in DNP3. This object contains parameters for control-code, count, on-time and off-time. To operate an AUTOBITS output point, send a control-code of latch-On, latch-Off, pulse- On, pulse-Off, Trip or Close.

Section 14 1MRK 502 043-UUS B Monitoring 14.8 Disturbance recorder 14.8.1 Functionality The Disturbance recorder function supplies fast, complete and reliable information about disturbances in the power system. It facilitates understanding system behavior and related primary and secondary equipment during and after a disturbance. Recorded information is used for different purposes in the short perspective (for example corrective actions) and long perspective (for example functional analysis).
Page 469: Memory And Storage
Section 14 1MRK 502 043-UUS B Monitoring Disturbance recorder collects analog values and binary signals continuously, in a cyclic buffer. The pre-fault buffer operates according to the FIFO principle; old data will continuously be overwritten as new data arrives when the buffer is full. The size of this buffer is determined by the set pre-fault recording time.
Page 470 Section 14 1MRK 502 043-UUS B Monitoring The header file (optional in the standard) contains basic information about the disturbance, that is, information from the Disturbance report sub-functions.

Section 21 1MRK 502 043-UUS B Time inverse characteristics Section 21 Time inverse characteristics 21.1 Application In order to assure time selectivity between different overcurrent protections in different points in the network different time delays for the different relays are normally used. The simplest way to do this is to use definite time delay.
