FI830F 3BDH000032R1 Forward operation (cooling) or reverse operation (heating) is selectable; direct input from temperature sensors is possible; sampling period is 500ms; 2-point internal alarms for each loop; for the 2-loop mode, a current transformer is connected to each loop to detect heater breaks. Since the blade forming mould is divided into several circuits for heating, a master controller is used to coordinate the heating temperatures of the various circuits, while each single circuit carries out the temperature acquisition of its own area, as well as the heating of the temperature field, the thermostatic maintenance and the cooling work.

FI830F 3BDH000032R1 is a user application system developed based on configuration software, and its structure consists of five parts: main control window, equipment window, user window, real-time database and operation strategy. The control flow diagram of the specific moulding process is shown in Fig. 4, from which it can be seen that the real-time temperature values of each single loop collected by the sensor measurement and temperature acquisition module are all deposited into the real-time database, and the user can observe the current temperature values of each single loop by calling up the real-time database in the master window, so as to deal with the temperature anomalies accordingly.

The operation status of FI830F 3BDH000032R1 output control module can be learnt through the device window. At the same time, in each stage of the blade mould forming process in Figure 4, the temperature rise and constant temperature maintenance processes are stored in the application system with the corresponding control strategy, that is, the corresponding control strategy is run at each stage to achieve the expected forming process. The user can know the system status of the current stage of the moulding process through the user window, and when the alarm message shown in Fig. 4 appears in the user window, the user can manually carry out a series of actions such as heating up, cooling down, thermostatic holding, starting and stopping of each channel according to the alarm message shown. Finally, each stage of the moulding process to meet the process requirements. User application system of five parts of the specific structure of the composition is as follows.
