Description
TC-PCIC02 Control Interface Module
TC-PCIC02 calls the switching function block FC20, the pulse width modulation generator block TC-PCIC02 and the background data block DB20, the parameter measurement function block FC21, the excitation signal regulation function block FC22, the system chain protection block FC23, the function block FC24 for communication with DB in a cyclic manner by judging the state of the operating variables and the state of the PLC input contacts from the upper level industrial control computer Wincc or the touch screen TC-PCIC02, the whole program structure is shown in Fig. 7. DB communication function block FC24, the entire program structure shown in Figure 7.
TC-PCIC02 when the PLC power initialization is completed, into the OB1 main loop block, and scanning function block FC24 to achieve communication with Wincc and TC-PCIC02, access to operating information and connect the PLC input contacts and auxiliary nodes such as M1.0, call the appropriate function block FC, complete the corresponding control operations; at the same time, the relevant data and parameter status uploaded through FC24 to Wincc, to achieve remote monitoring. Wincc to realize remote monitoring. At any moment when there is an abnormality in the system parameters, the PLC will call the chain protection block FC23 to put the system in the protection standby state, and display the fault to the Wincc and TP270 operator interface to inform the system operator.
TC-PCIC02 has to go through type tests and performance tests before leaving the factory and fully meet the technical requirements before going into production or continuing production. These tests or test data include the motor’s voltage, current, speed, power, turnover rate, frequency, efficiency, temperature, resistance, etc. These parameters are obtained through the no-load test, load test, temperature rise test, torque test and other tests on the basis of meeting the accuracy of TC-PCIC02 three-phase asynchronous motor test methods and other relevant national standards and their safety requirements. The intelligent high-voltage motor test system introduced in this paper has an automatic test function, which can well reflect the motor performance and its quality through the measured data.
