The invention discloses a network terminal cabinet system for a distributed control system (DCS) instruction, and belongs to the technical field of terminal cabinets. The network terminal cabinet system comprises a DCS instruction input terminal, a DCS instruction output terminal, a running status terminal, a process control terminal, a control linkage terminal, a power module, a DCS instruction input and output module, a programmable logic controller (PLC) data processing module, a status collection module and a communication terminal, wherein the DCS instruction input and output module, the PLC data processing module and the status collection module are connected with the power module; the communication terminal is connected with the PLC data processing module; the running status terminal is connected with the status collection module; and the PLC data processing module is also connected with the DCS instruction input and output module and the status collection module. The system is low in cost, has a DCS instruction status variation and variation time recording function, and can upload recorded information to a substation supervisory control and data acquisition (SCADA) system, acquire the running status of each loop of a motor control center (MCC) in a centralized way, perform data processing and remotely transmit data to a DCS instruction room.
