S7-300/400 CPUs: Temperature Recording in the S7-CPU by Means of Pt100 Resistivity Thermometer and SITRANS TK-L Measuring Transducer

Problem Almost everywhere where products or materials are processed or worked, the temperature has a decisive influence on the quality of the final product and the course of the process respectively. It is thus necessary to record the temperature, to interpret its influence and to specifically react to changes in temperature using control technology. Solution The device combination of SIMATIC

S7-300 Memory Cards -- Product information -- Technical data

What points do you need to remember during the handling of micro memory cards?Description: This entry describes how to work with MicroMemory Cards (MMC). A sample project is also included in Point 4. Theprogram shows how you can check whether specific data in a data blockis located in the load memory.1. How should I save blocks or configuration data on the MMC which are transferred online to the

Transfer of analog values from and to the PROFIBUS DP slave

QUESTION: The analog values are transferred only in part or not at all. How can I clear this problem? ANSWER: If none or only part of the analog values are transferred, or the transferred values are incorrect, then this might have something to do with the length of the consistent data of the slave (affects S7-300/400 CPUs).If more than 4 bytes (or exactly 3 bytes) are consistent over the entire

S7-400 CPU 41x -- Configuring and programming communication -- Configuring the PROFIBUS interface

What differences are there when configuring S7 connections?Description: In this description of how to configure S7 connections it is assumed that all the stations are in one S7 project. Types of S7 connections: With S7 connections you differentiate between bilaterally configured and unilaterally configured S7 connections. Bilaterally configured S7 connectionsYou recognize bilaterally configured

How can you delete unused tags or objects from a WinCC flexible project?

Instructions:In order to reduce configuration work, parts of a project are often copied and inserted into a new project. Here, tags and objects are copied, which are no longer used in the newly created project. WinCC flexible provides a function which can be used to have these unused tags displayed. In the "Edit" menu you select the command "Find in project...". In the window that opens you

Copying HMI projects integrated in SIMATIC STEP 7 at file level

QUESTION:   Can I copy a SIMATIC WinCC flexible project integrated in SIMATIC STEP 7 at file level?  ANSWER:   Copying of HMI projects integrated in STEP 7 at file level (e.g. with Windows Explorer via Copy/Cut and Paste) is not possible in combination with WinCC flexible.  By copying of HMI projects integrated in STEP 7 (*.hmi) at file level you lose internal references from the WinCC flexible

How do you archive projects in WinCC flexible and which files are required?

Project archiving and migration If you wish to archive a WinCC flexible project, you can reduce the volume and file size significantly by archiving just the following project files. Please refer also to the notes at the end of the entry on migrating WinCC flexible projects (opening a WinCC flexible project that is based on a previous version). No. Project archiving in WinCC flexible 2007 and
