ARE YOU LOOKING TO EFFECTIVELY SHARE DATA BETWEEN PROFIBUS AND PROFINET NETWORKS? THE SOLUTION IS THE S7-1200 PLC
Is your network ready for planned upgrades to your automation, drive, and data systems?
Even if you are not moving toward the newest trends in the industry, like the Industrial Internet of Things (IoT), cloud computing, Big Data, and Industry 4.0, your automation systems are likely in need of an upgrade. Whether to replace obsolete equipment, improve speed and accuracy of production, or to better integrate the plant floor with the main office, upgrading means staying relevant in your industry.
An underutilized item in your automation toolbox is the scripting capability embedded in your HMI software.
Quite often, the data generated by a control system requires further manipulation, massaging if you will, retransmission on alternate protocols, or long term storage on an MES/MRP system.
The default approach to these issues is typically:
- Programming in the PLC with file and data commands that are not ideally suited to the task
- Implementing a solution on a PC-based system so as to utilize third party software such as Excel
- Purchasing protocol conversion hardware such as gateways
- Saving data to text or csv files for further processing by custom written programs
While these methods can provide the required functionality, they may not be best solutions from a cost/time perspective. Depending on your role in the overall automation solution, these approaches might not even be viable.
More than just another interface, IO-Link is the smart concept for standardized linking of switching devices and sensors to the control level by means of an economical point-to-point connection. The IO-Link communication standard at the fieldbus level enables centralized fault diagnostics and, because parameter data can be modified dynamically direct from the application, the devices can be adjusted to the prevailing production requirements during operation.
Radio frequency identification, or RFID, is a technology using radio waves to automatically identify people or objects. The most common usage is to store a unique number, which identifies the item, on a microchip attached to an antenna. The chip/antenna combination is called an RFID transponder or an RFID tag. This tag then transmits the identification number, and possibly other stored information, to a reader. The reader then supplies this information to a PLC system or directly to a computer via standard industrial communication methods; Ethernet, Fieldbus, etc.
