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.
The control station communicates with the outstations via Ethernet using the DNP3 and IEC 60870-5 telecontrol protocol.
SIMATIC S7 stations also allow the use of email as the default mechanism for transmitting error conditions or warnings from industrial plants to a control center or operating staff.
MindSphere is the cloud-based, open IoT operating system from Siemens. Using the "MindConnect IoT Extension" upgrade, it is possible to connect devices to MindSphere over MQTT.
For remote transmission, large SINAUT projects with multiple process stations and the corresponding communications processors are often found in existing systems. To allow for greater flexibility in the existing system, the large SINAUT projects should be subdivided into smaller and more manageable sub-projects, then monitored and controlled from the same central control center.
In existing SINAUT plants with SIMATIC S7-300/400 and the respective TIM modules for remote transmission, S7-1200 stations can also be integrated using CP 1243-8 IRC.
This application example handles the data exchange via S7 communication between a S7-1500 or S7-300 as head PLC (client) and several S7-1200 substations (servers).
An introduction to IP based remote Networks and to the related product range of Siemens. For the possible configurations of an IP based remote network there is an overview along with the requirements and the link to the configuration description.
With the integration of the SINAUT project planning in the TIA Portal, the complete communication configuration takes place in one tool. The TeleControl portfolio has been expanded with the TIM 1531 IRC, which can be connected to the central control station as a stand-alone device. This means that one or more RTUs can be used as substations in TeleControl systems with the SINAUT ST7 protocol.
Due to its versatility, FTP has established itself as a standard for data exchange. It is independent of the type of connection and the operating system. It additionally offers protection mechanisms such as assigning access rights and explicitly sharing paths. The data exchange can be protected by communication encryption (FTPS).
This media system provides you with comprehensive, visually appealing information with numerous general and technical videos of Industrial Security.
In automation technology, old plants are increasingly having to be completely or step by step converted from SIMATIC S5 to SIMATIC S7-1500. These examples are intended to demonstrate how a SIMATIC S5 can be coupled to a modern SIMATIC S7-1500 via Industrial Ethernet. This application example describes the scenarios for the ISO transport protocol.
In automation technology, old systems still running with SIMATIC S5 have to be upgraded – completely or step by step – to the latest version of SIMATIC S7-1500 due to the end of product lifecycle. These examples shall demonstrate how a SIMATIC S5 station communicates with a SIMATIC S7-1500 station via Industrial Ethernet (ISO on TCP).
An automation infrastructure contains S7-1200 substations which shall communicate cost-effectively with a central station via the mobile communications network or via Ethernet. The TeleControl Server Basic V3.1 software is installed in the central station.
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.
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.
To ensure secure operation in a digital enterprise, data transmission can be encrypted using Virtual Private Network (VPN) to protect against data espionage and tampering. This application example shows you how you can use the SCALANCE S615 industrial security appliance and the CP 1543SP-1 communication processor to establish a VPN connection.
An automation structure contains a SIMATIC S7-1200 sub-station that communicates wirelessly with a central station via the internet and is monitored and controlled by a service operator via remote access.
A SIMATIC S7-1200 station shall be used to send important messages as SMS message to mobile maintenance staff via the CP 1242-7 GPRS V2.
