Point T1 and T2, is connected respectively to AI0 and AI2 ports.A products have a pressure switch, do not have flow switch；B products have one
Flow switch, does not have pressure switch.To reduce resource occupation, the pressure switch of A products and the flow switch of B products are all connected to
On On-off signal point DI2.0.For description is simple, it is assumed that two products are connected to same motor control point DO0.0, and same
Individual analog quantity speed control output point AO0.
In order to realize the standardization of product, referring to Fig. 1, automatic control system is handled as follows：
Step 101：One configuration parameter table DB0, each equipment or part for recording corresponding product, one are set
The record value of record represents the quantity of the equipment or part corresponding to the record, and the title of record represents setting corresponding to the record
The title of standby or part, configuration parameter table DB0 can be used for distinguishing A products and B products；
Configuration parameter table, variable parameter table and the List of lists for using within a context are bivariate table, have recorded many
Bar is recorded, and every record includes four fields, i.e.,：Title, data type, record value, explanation.
Step 102：Variable parameter table DB1 is set, for storing the zero point value of analog sensor or output port and expiring
Angle value, every record correspondence one zero point value or a full scale value；
Wherein, the corresponding temperature sensors zero of record storage analog quantity temperature acquisition sampling point T1 of entitled " DB1.DBD0 "
Point value；The corresponding temperature sensor full scale values of record storage analog quantity temperature acquisition sampling point T1 of entitled " DB1.DBD4 "；Name
Referred to as corresponding temperature sensor zero point values of record storage analog quantity temperature acquisition sampling point T2 of " DB1.DBD8 "；It is entitled

Sample, the minimum data and maximum data that fan-out mouth can be gathered are also known.
Referring to Fig. 2, following parameter modification flow can be carried out in the implementation procedure of the above method：
Step 201：The username and password of active user is received and checks, to judge whether active user has parameter
Modification authority, if parameter modification authority then enters step 202；Otherwise, modification interface is not entered.
Step 202：List of lists is updated, to change the zero point value and full scale value of analog sensor.
In order to carry out the validity judgement of sampled value, referring to Fig. 3, in step 104, by the sampled value of analog input port
Conversion also includes before being an externally input value：
Step 301：Sampled value is obtained from analog input port；
Step 302：Judge sampled value whether analog input port corresponding with sampled value zero point value and full scale value
Between, if it is, the sampled value conversion of analog input port is an externally input into value.When sampled value is in zero point value and full scale
When outside the scope that value determines, alarm signal is sent, remind staff to be adjusted to equipment in time.
The above, only presently preferred embodiments of the present invention is not intended to limit the scope of the present invention.
