ARE YOU LOOKING TO EFFECTIVELY SHARE DATA BETWEEN PROFIBUS AND PROFINET NETWORKS? THE SOLUTION IS THE S7-1200 PLC
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.
Watch a servo or drives person in action, and it is generally only a matter of time before they are looking at a velocity vs time trace to fine tune the performance of a motor system. The reason: events that are occurring much faster than the eye can observe must be scrutinized. In Siemens TIA Portal, we have the ability to generate and save traces of our PLC logic.
Over the last three years, Siemens has been rolling out their new generation of PLC hardware. These PLC platforms, the S7-1200 and S7-1500 families, are programmed using the newer TIA Portal development environment, and offer many advantages to their legacy counterparts in the S7-200, 300, and 400 families. First and foremost, these tag-based controllers share the new Portal programming software, which means you have one software platform to cover the full breadth of product (also including most 300 and 400 series).
Getting good diagnostic information about your system components doesn't need to be a hassle anymore. With Siemens S7-300, S7-400, and S7-1500 series PLC’s, a simple checkbox can enable System Diagnostics that work in conjunction with Siemens Comfort series HMI’s. Ok, sounds good, but what is it?
