SIMATIC STEP 7 Basic (TIA Portal) is a price-optimized subset of STEP 7 Professional controller software in the TIA Portal that can be used for engineering SIMATIC S7-1200 Basic Controllers and configuration of SIMATIC HMI Basic Panels, as WinCC Basic is part of the software package.

ScreenShots: Software Description: Siemens SIMATIC STEP 7 software is theprofessional tool for the SIMATIC S7, SIMATIC C7 and SIMATIC WinACautomation systems. It enables the user to use the performancecapability of these systems easily and conveniently.

SIMATIC STEP 7 contains convenient functions for all phases of anautomation project: – Configuring and parameterizing the hardware – Specifying the communication – Programming – Test, start-up and service – Documentation, archiving – Operating/diagnostics functions SIMATIC STEP 7 program tools: 1. SIMATIC-Manager: The SIMATIC Manager manages all data belonging to an automationproject, regardless of the target system (SIMATIC S7, SIMATIC C7 orSIMATIC WinAC) on which they are implemented. It provides a common entry point for all SIMATIC S7, C7 or WinACtools. The SIMATIC software tools that are necessary for processingthe selected data are automatically started by SIMATIC Manager.

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. The following functions are available: – Definition of symbolic designations and comments for the processsignals (inputs/outputs), flags and blocks – Sorting functions – Data exchange with other Windows programs The symbol charts that are generated when this tool is used areavailable to all software products. Changes to a symbol parameterare therefore automatically recognized by all tools. Hardware configuration: The tool Hardware Configuration is used for configuring andparameterizing the hardware used for an automation project. Thefollowing functions are available: – Configuration of the automation system Racks are selectedfrom an electronic catalog and the selected modules are assigned tothe required slots in the racks. – The configuration of the distributed I/Os is done in the same wayas the configuration of the non-distributed I/Os; channel-granularI/O modules are also supported.

– CPU parameter assignment: Properties such as restart characteristics and cycle-timemonitoring can be set menu-driven. Multicomputing is supported. Theentered data are filed in system data blocks in the CPU. – Module parameter assignment: The user can specify all the adjustable parameters of the modulesin input screen forms. Adjustments via DIP switches becomeunnecessary. Parameterization of hardware modules occursautomatically during the CPU’s acceleration.

Thus, a change of amodule can be made without another parameterization. – Function module (FM) and communications processor (CP) parameterassignment: This parameterization also occurs within the hardware configurationin the same way as the parameterization of the other modules. Forthis parameterization hardware-module-specific screen forms andrules are provided for each FM and CP (is included in the FM/CPfunctions package). The system prevents faulty inputs by offeringonly allowed entry options on the parameter assignment screenforms.

Communication configuration: – Configuring and display of communication links – Time-driven cyclic data transmission via MPI: – Selection of communication partners – Entering of data source and data destinationin a table.Generation of all system data blocks (SDBs) to be loadedand their complete transmission to all CPUs take placeautomatically – Parameterization of the selected communicationblocks in the customary programming language (e.g., LAD). – Event-driven data transmission – Definition of the communication links.

– Selection of the communication function blocks (CFBs) from theintegrated block library. – Parameterization of the selected communication blocks in thecustomary programming language (e.g., LAD). System diagnostics: System diagnostics offer the user an overview of the status of theautomation system. The display can be in two different forms: – Display of text messages, which can be output directly andquickly. – Pixel-graphics display within the Hardware Config display,offering the following options: – Display of general module information (e.g., order number,version, designation) and module status (e.g., faulty) – Display of module faults (e.g., channel faults) of thecentral I/O and DP slaves – Display of alarms from the diagnostics buffer For CPUs, additional information is displayed: – Causes of malfunction during user program execution.
