This invention discloses a communication structure for a test module based on a continuity tester, comprising: a continuity test host, having a host MCU and host data signal output and input terminals connected thereto; a continuity test point board, having multiple communication interfaces, each of which is connected to a test bus via a corresponding first switch and grounded via a corresponding second switch; and multiple communication node modules, each having a module indicator light, a node MCU, and node data signal input and output terminals connected thereto. The module indicator lights, node data signal inputs, and node data signal outputs are all connected to their respective communication interfaces via module indicator light control lines, and the module indicator lights are also connected to the host MCU via indicator light enable signal lines. This structure forms a communication network connecting all test modules, enabling the test host to read and save the test results and parameter settings of the test modules, thus achieving traceability of the tested products.
