In the following, you will find instructions on how to replace the discontinued module and determine compatibility information.
So that the value of a S7-300 string can be displayed in WinCC Unified Runtime, the length of this string data type must be specified in the corresponding S7-300 data block.
The SITOP PSU6200 power supply has a diagnostic interface "COM" whose signal can be evaluated via a digital input in a higher-level controller, e.g. S7-1200 CPU, S7-1500 CPU and S7-300 CPU / S7-400 CPU.
In the following we explain the local data addressing with S7-300/S7-400.
Use the prepared and handy faceplates and function blocks of this application example in order to connect the uninterruptible SITOP UPS1600 power supply to your plant. Furthermore, you can find out how you can shut down your plant in a defined state for longer power failures and how to secure process values.

Today's process engineering systems are often made up of system landscapes that have grown over many years and include control systems from different manufacturers. The main challenge is to integrate various systems from different manufacturers into one operator control and monitoring system. The automation system that is responsible for the sensors and actuators is of secondary importance.
Overview of the firmware versions of all S7-300 CPUs
You get this message in the diagnostics buffer of STEP 7 (TIA Portal) if the S7-300 CPU recognizes an access error to the MMC.
UL Certificate of Compliance for Programmable Controllers Simatic System S7-300 or SPPA-T3000 No. E116536 (English) E116536
Certificates and approvals are available on the Siemens Service and Support pages.
There are several reasons why the S7-300 station will not start up with Ethernet or PROFIBUS CP.
China Classification Society (CCS) Approval of the SIMATIC Systems S7-300/M7-300 HB20PTB00004_12
The File Transfer Protocol (FTP) is one of the classic, standardized options of exchanging data with PCs or any heterogeneous computer system. This entry shows how FTP communication is realized in a SIMATIC S7-300/400 station. ...
This migration guide contains recommendations and notes for users who are currently using SIMATIC S7-300/400 automation systems and plan to migrate to the new SIMATIC controller generation S7-1500.
This application supports in integrating the Weihenstephan Standards into SIMATIC controllers and the motion control system SIMOTION. The Weihenstephan Standards (WS) define a universal communication interface for connecting machines to higher level data acquisition systems or MES (Manufacturing Execution systems). They also define the data which must be provided for acquisition.
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.
When the operating mode changes from STOP to RUN, with the S7-1500 the substitute values fail and the values of the output modules flicker.
The S7-300/S7-400 and the S7-1200/S7-1500 SIMATIC controllers are free of silicone releases (in the specified operating temperature range).
