Technical Field

Background

When an industrial process controller such as a PLC (programmable logic controller) and a DCS (distributed control system) are used for carrying out program logic debugging, testing and simulation demonstration, operations such as simulation and emulation need to be carried out on input/output signals, and operation response of field equipment is virtually realized, so that a logic program can be completely operated. When the traditional manual signal forcing and simulating operation mode is adopted, the smoothness and the integrity of the operation of the logic program cannot be ensured. If the mode of programming a debugging program and hanging a simulation program (equipment) is adopted, the requirements of smooth and complete operation of the logic program can be met under the condition that the coverage of the debugging program and the hanging program is enough. However, as the debugging program and the plug-in program need to be customized and developed, the universality, the economy and the timeliness of the device are limited, the use is troublesome, and the device needs to be connected with field devices;
