The "LPNDR" block library includes several function blocks. With these you can read various device and status information from a PROFINET device and describe parameters.
After adding a CPU or an FM module, the SIMATIC S7-300 CPU no longer switches to RUN mode but remains in STOP mode.

Automation projects often require intensive, high-performance data exchange between SIMATIC S7 controllers and PC systems. OPC UA is establishing itself more and more, particularly with regard to Industry 4.0, as a central communication component in the PLC world as well. Measured performance data on the OPC communication provide you with reliable statements here.
Library for controlling the SIPLUS HCS4x00 heating control system as PROFINET IO device or as PROFIBUS DP slave on a SIMATIC S7-300/S7-400.
It is important to estimate the response times in a system made up of controllers, distributed IO, PCs or also components of the industrial identification already during the planning phase of a plant. With measured performance data on industrial communication with SIMATIC S 7 components, you receive secure statements here.
If you want to store and process only few, essential PLC data on PCs, then you will get with this example a convenient alternative. This application shows you how the production data of all common S7 CPUs can be stored directly in the files of a Windows computer.
Attached are the latest Support Packages for several TIA Portal versions ready for downloading.
By now, TCP/IP-based Open User Communication (OUC) is the standard for communication with SIMATIC S7-CPUs.
In the field of automation, the TCP protocol based on Industrial Ethernet is typically deployed for safe, time non-critical (> 25 ms) and multi-system communication.

A SIMATIC S7-300/400 is to control a SINAMICS S120 drive via PROFINET or PROFIBUS DP. The realization is to be done with the engineering tool STEP 7 V5.
The SIMATIC application Winder and Tension Control is part of the Converting Toolbox and was developed with the objective to provide common functions which are necessary for any kind of converting machine.
The “Message Queue Telemetry Transport” is a simple protocol on TCP/IP level. It is suitable for messaging between devices with minimum functionality and for transmission via unreliable networks. With the function block from this application example, the MQTT protocol is implemented into a SIMATIC S7-1500, SIMATIC S7-1200 and SIMATIC S7-300.
An overview shows the properties, advantages and special features of the protocols TCP, ISO-on-TCP, UDP and ISO Transport.
The SITOP PSE200U selectivity module with single-channel signaling enables you to monitor 24V load circuits.
Use the functions in the "Online" menu if you want to download the project data from the device to your programing device.
The S7-300 CPU 318-2 DP listed in the following will be finally discontinued, following a 10-year phase-out period.
This entry explains the I-device function and gives an overview of the various tasks that can be realized with it. These functions are explained in configuration and application examples.
The PROFINET CPUs S7-300, S7-400, S7-1200, and S7-1500 can only be configured as NTP clients for time synchronization. With this STEP 7 library you can turn a SIMATIC S7 CPU into an SNTP server and thus realize a simple time synchronization of automation cells.
