At a Glance

The PLC Engine allows data processing in production lines. It connects controllers, devices, SCADA systems and databases from various manufacturers. It processes the data and dispatches them between the connected devices and other systems. It collects data, manages them and creates overviews for OEE applications.
Additional all the data can be handled over OPC. This are processed data and all data from the connected controllers, devices, OPC systems and databases.

PLC Engine is the perfect component for using it for communications in Industrie 4.0.

	Boosts the PLC communication with logical optimizing of the requests. Often this will happen to error texts from the controllers. The messages need to be fetched normally if the corresponding error number is changing and a new error condition becomes true. Without any change to Your SCADA system the communication speeds up. The main reason is less load on the communication line.
	Exchanges data between controllers and devices without PLC programming or SCADA functionality. That's how it's done: PLC Engine is reading the data from a controller or device and writes them into another controller or device. The writing normally takes place if the data are changing. With configurable triggers data which are depending on other data conditions for the writing can be defined. The data will converted if necessary. This is important if both controllers are different: One Siemens S7, the other a Rockwell Control Logix. More complex handling is possible, too: Collecting of data from one or multiple controllers, do some calculation with the data, and write the result to a controller or device. Of course, any OPC compatible system can use the same data also.
	Collects and processes data PLC Engine is reading data from one or more controllers. The data are collected and possibly calculated or normalized. If all data are in place they are ready to process for other systems or OPC access. During the logical processing the data are blocked for access. Syncronous data access are waiting until the collection is finished. Configurable error conditions are configurable: If one of the controllers is not available constant data are used, or an error number is processed.
	Exchanges data with common databases. You can read data from controllers and write them directly into common databases - with optional calculations. Data readed from databases can be written into controllers, too. All the data are available for OPC systems also.
	Collects data over long time for OEE into a local or external database. So easily OEE applications can be build. The integrated websites are offering the collected and calculated data directly as curves or other. Additionally the data can be handled over OPC.

Functionality

• Read and write data from industrial controllers and devices.
• Exchange data with databases. Read, write, update, delete.
• Read and write files, check for changes, create files, delete files.
• Send emails.
• Read and write data over OPC UA and Classic OP.
• Sequence chains with conditions for changing the actual step.
• Calculate data. Round, basic calculations, constants, conversions, reinterpretations.
• Check data. AND OR XOR NOT. Comparisons for equal, less, greater. Float number plausability.
• Manage data structures. Create them, decode structures.
• Collect data. Combine and separate texts. Combine and separate binary data.
• Lots of triggers: Time trigger, data change trigger, bit trigger, file create trigger, file modify trigger, directory change trigger.
• Subroutines.

Online diagnostics for shortening the configuration time

• Watch connections and their state.
• Watch variables. Status, value, who needs them.
• Watch logic tables and their behaviour.
• Watch and modify single variables (Status variable).
• Diagnostics logger for long term watching.

Configuration

The configuration works in graphical style or with simple lists.

Lot of Wizards simplify this.

The example logs from barcode reader, adds a timestamp and writes both into a .csv file.

This example reads a barcode, gets the print data from a database and prints the result.

Diagnostics boost the startup in plants. Use Your smartphone or tablet and all of the status displays.

The diagnostics logger handles longer running information collecting.
