1. Must be run in Botulu software Step7, Configuration king and unity to communicate with PLCMust be run in Botulu software Step7, Configuration king and unity to communicate with PLC2. The Configuration king and unity cannot read and write the PLC data because of this setting.3. Add a dense ladder diagram to the PLC,
the output is often relays. The PLC ladder diagram logic is actually a computer program that users can input and change. Note that the push buttons of the two inputs are always open, but the logic of the PLC ladder diagram has a
At present, the famous Hardware website Tom's Hardware also updated its own graphics ladder diagram. Let's take a look.This timeGraphics ladder diagramFrom TNT2 in ancient times to the latest Nvidia Titan X. SlaveLadder chartWe can see that Nvidia has no rivals in the high-end field, but it is strange that there is no AMD Radeon Pro Duo in the

artifact object to a generic use case, and then establish a dependency between the artifact element and the generic use case. With the artifact element, you can attach a separate document to a use case:An activity diagram can represent a business or software process as a workflow through a series of actions. These actions can be done by countless objects, including people,
Concept ---- Data Flow Diagram (DFD)
Data Flow Diagram(Date flow divisor, DFD) is a tool used in the SA method to represent the system logic model. It graphically depicts the process of data flow and processing in the system, because it only reflects the logical functions required by the system, it is a function model.
A Data Flow

3. Software Requirement Specification: Also known as the software specification, which provides detailed descriptions of the features, performance, user interface and operating environment of the developed software. It is an agreement between the user and the develope
Causality diagram is a formal language, and the specification description described in natural language can be transformed into a causal diagram. A causal diagram is actually a digital logic circuit (a combined logical network), but instead of using standard electronics symbols, it uses a slightly simpler notation, whi
