if the response message of the tested device is not received or the response message of the tested device is checked to be wrong, executing a round of reading the IP address message msg2 every 5 seconds, and if the response message of the tested device is not received after 1 minute, returning to execute the high-temperature aging IP address configuration.
7. The power distribution terminal high temperature aging communication configuration method of claim 6, characterized in that: the LED lamp flickers and displays the IP address responded by the tested equipment, and the IP address which is correct in response of the tested equipment is not received; if not, the correct IP address is indicated to be received by the response of the tested device.
8. The power distribution terminal high temperature aging communication configuration method of claim 4, characterized in that: the factory IP address polling state includes:
the control module sends a frame of IP address reading message msg2, simultaneously lights the operation lamp for 0.2 second, lights the communication lamp for 0.2 second if the correct message of the tested device responding to the default IP address is received, and shows a normal state, and executes a round of IP address reading message msg2 every 3 seconds under the normal state;
if the response message of the tested device is not received or the verification of the response message of the tested device is wrong, executing a round of reading the IP address message msg2 every 5 seconds.
9. The power distribution terminal high temperature aging communication configuration method of claim 8, characterized in that: the LED lamp flickers and displays the factory default IP address responded by the tested equipment, and indicates that the correct IP address responded by the tested equipment is not received; and if the test result is not displayed in a flashing manner, the correct factory default IP address is received by the response of the tested device.
10. The power distribution terminal high temperature aging communication configuration method of claim 9, characterized in that: if the response message can not be received within 1 minute, if the response message is reset to a high level, returning to execute communication connection judgment;
otherwise, if the reset is low level, the high temperature aging IP address configuration is executed.
