For this purpose, Siemens has developed the optimal language for Step 7, which is also used in this language. What this program does is to program the logic of these PLCs how to process the input data and ultimately what to do in the output. For CPUs, additional information is displayed: - Causes of malfunction during user program execution.Ĭopy Download Link Copy the download link and paste to your browser.The PLC is in summary a hardware interface that initially reads data from digital inputs and sensors from the inputs, then processes it according to the program in the memory, and finally uses the hardware controllers and output commands He does the job. The display can be in two different forms: - Display of text messages, which can be output directly andquickly. System diagnostics: System diagnostics offer the user an overview of the status of theautomation system. Event-driven data transmission - Definition of the communication links. The system prevents faulty inputs by offeringonly allowed entry options on the parameter assignment screenforms. Thus, a change of amodule can be made without another parameterization. Theentered data are filed in system data blocks in the CPU.Īdjustments via DIP switches becomeunnecessary. Hardware configuration: The tool Hardware Configuration is used for configuring andparameterizing the hardware used for an automation project. Changes to a symbol parameterare therefore automatically recognized by all tools. The symbol charts that are generated when this tool is used areavailable to all software products. Symbol-Editor: With the tool Symbol Editor all global variables in contrast tothe local formal parameters that are declared when the blocks areprogrammed are managed. It enables the user to use theperformance capability of these systems easily andconveniently.
