IC698CPE030 Automation spare parts module

IC698CPE030 ensures that the program logic is reliable and resource conflicts are avoided by using the resource away principle. For this purpose, the Reference Date in STEP 7 is used to check the resources (I/O points, M, T, etc.) in the original S7 system to confirm the resources that have not been used by the original S7 system, and then they are assigned to the S5_Run_Program function block, and try to make the resources of this function block concentrated together, so as to ensure that the resources in the S5_Run_Program program do not overlap with the resources (I/O points, M, T, etc.) in the original S7 system to avoid conflicts and to improve the convenience and modifiability of program design.

IC698CPE030 edits symbol quantities to improve program readability. Use the Symbol Table in STEP 7 to edit the symbol variables, such as “BUZZER” (na-ba-ba) as the symbol variables of Q0.7, which makes reading the program and designing the program easier to understand and read.

IC698CPE030 analyzes the characteristics of the control object to ensure the safety of the control object.The object controlled by the S5_Run_Program function is a high-power DC motor. In order to ensure that the DC motor does not occur “vector magnetic flying car” situation, it must be ensured that when starting the motor, the first to the excitation power supply, in order to ensure that the excitation power supply to the case, in the armature to give the motor power; in the case of stopping the motor, the order is reversed, i.e., first cut off the armature power supply, and then cut off the excitation power supply, for this reason, the S5 _ Run_ Program function should ensure the safety of the motor. Program function should ensure the safety and reliability of the motor.
