Abstract: This paper analyzed the characteristics of feed terminal remote signaling and remote control circuit of distributed network and
designed a test device with the function of remote signaling and remote control. The PLC was selected as the hardware device control core,
including the human-machine interface (HMI) touch screen, remote signaling output circuit, remote control input circuit, and so on. The test
device completed the functions of remote signaling dislocation test, SOE resolution test, remote control event recording test with the PLC I/O
port. The field application shows that this device has the characteristics of high precision, simple operation, easy usage and stable operation,
reaching the expected functions and precision index.
Key words: feed terminal unit; remote signaling and remote control; PLC; SOE resolution
