Through industrial control, sword sword sealing throat!
What do we usually face in electrical engineering? Here we only need to grasp the key, and often it is an outline, and we can do more with less. Today we will introduce the overall structure of the electrical engineering project.
General electrical engineering projects are divided into eight modules:
1, the mastery of process requirements.
2, electrical selection, out of the list.
3. Schedule progress.
4, out of electrical schematics.
5, field wiring.
6, program design.
7, on-site debugging.
8, project data, and after-sales service.
Here we look one by one:
1. The mastery of process requirements can be accurately grasped. In the actual contact with the customer, the customer may not always be able to express clearly. When you do the part and communicate with the customer, the customer has new ideas. At this time, the demand will change, so we must have a fixed template to guide our customers from the beginning, and use the entire framework to achieve our mastery of needs as a whole. It will be explained in detail in our Action List and Timing Chart.
2, electrical selection, including low-voltage electrical selection, selection of various types of sensors, PLC selection, servo, frequency conversion selection. Selection of devices Some common ones we need to organize these are usually in order to avoid temporary access to relevant information and avoid unnecessary waste.
Here's a sample diagram for everyone:
3. For the progress of the project, please refer to our "PLC Project Plan"
4. In the schematic part, we can refer to our drawing specification:
As shown below: 
5. Regarding the wiring part, the common rookies will be guilty of what problems. We have made one by one explanation in the wiring specification. 
6. With regard to the program design part, we have several parts:
A, IO allocation table, in the beginning of the program, these memory allocation must be assigned to the framework
As shown below, you can use it as a reference. 
B, PLC programming architecture, as shown below: 
7. Regarding on-site commissioning, many problems may not be considered at the beginning of our program design. At this time, we need to sum up more and more, which is also the accumulation of experience.
8, in this section we can refer to the following figure: 
These records are detailed for future project maintenance and the project handover will be very clear. Above, we basically listed the eight major modules of electrical engineering. In fact, there are still many details in each module. This is just a guide. If you need further understanding, please pay attention to our follow-up courses. In the follow-up courses, we will Everyone from a layman led the world of industrial control, so that you really become a big coffee-class person in the field of industrial control.
If so, add WeChat DS15295506175 to share with you industry control industry, top consulting, to help you create a different life! Verification of losses: through industrial control.
