No malfunction hardware anomalies occur that suggests that, terminates；
Step (b): read file acquisition information bank and policy library；Judging that reading is the most successful, picking data if just sending,
Enter step (c), suggest that the malfunction that file is abnormal if not, terminate；
Information bank refers to the massage set of the slave computer that all systems support；Policy library comprises sending strategy, the configuration successful not configured
After sending strategy, configuration strategy, forwarding strategy, grouping strategy.
Step (c): judge whether port configuration completes, if forwarding packet scheduling with regard to data: according to the difference of data type
Forwarding measuring point data packet to backstage, system normally starts；It is put into step (d) if not；
Step (d): formulate and configure strategy, it may be judged whether there is configuration strategy, if preserving file after just configuring port, puts
Configuration is masked as successfully, and system normally starts；The most just terminate.
Configuration strategy include configuring port whether start, number of devices and device type.Formulate configuration strategy step as it is shown in fig. 7,
Including:
Step (d-1): need configuration, amendment configuration to be masked as " configuration "；
Step (d-2): according to verification and, the effectiveness of data that communicates with slave computer of effective length and type judgement, if had
Effect is put into step (d-3)；It is put into step (d-4) if invalid；
Step (d-3): search information bank, obtains the response message communicated with slave computer；Enter step (d-5)；
Step (d-4): put and do not configure flag data extremely, it is impossible to correctly configure, terminate；
Step (d-5): reasoning: process the known message received, infers the type of slave computer；Enter step (d-6)；
Step (d-6): self study: observation, the reasoning to message；Enter step (d-7)；
Step (d-7): the port configuration whether there is reasoning in determination strategy storehouse, learning to arrive is tactful；If being put into step
(d-8)；It is put into step (d-9) if not；
Step (d-8): formulate port configuration strategy；Enter step (d-10)；
Step (d-9): put " not configuring mark ", prompting connects abnormal；Cannot correctly configure, terminate；
Step (d-10): judging that configuration is the most successful, if just putting configuration complement mark, completing correctly to configure；The most just
Put and do not configure sign prompting connection extremely；Cannot configure, terminate.
