One rudder feedback UF is output, and on this simulator PLC hardware, the output port of distribution is PQW312, but in servosystem is tested
In one-level, two grades and the test of three grades of servosystem different to this parameter request output valve, be respectively ± 1.4, ± 2.4 and ±
8.43, and servosystem requires that this port exports 0.45 in one-level zero testing, by simulator computer by numerical value and survey
Examination project status write sends array Sdy_zt [] and is sent to simulator PLC, and this simulator PLC after receiving the data, presses
Data protocol between simulator computer and simulator PLC resolves, and wherein, first determines whether test event (DB2.DBX3.2),
Again the value of corresponding data code word (DB2.DBW31) is assigned to auxiliary reclay MW72 in real time；So, as long as by this auxiliary reclay
Value be achieved that the dynamic control to analog output by the output of this port.
