The PLC (programmable logic controller) used for furnace control works together with the operation panel, where the panel view is an interface to control the operation and the PLC acts as the brain.
In this article we’ll cover some new technologies in PLC development and the associated benefits for furnace operation.
1.-Two-finger touchscreen
New touchscreen operation panels have the ability to recognize two fingers.
Although cell phones have had this feature for several years, this function is just being incorporated in industry, bringing with it great benefits:
• Allows you to zoom in the screens, mainly in graphics
• ‘Shift’ functions with dual-key commands – ‘Ctrl + another key’, etc.
• Increases security in some operations
2.-Direct connectivity with SQL databases
Today the entire computer systems industry operates through databases. However, some years ago this data transfer to a PLC was not possible directly, so it was necessary to use an additional computer with a SCADA system to communicate with the databases.
• The new PLCs include connectivity, mainly with SQL (Structured Query Language).
• They are very easy to program, so it is not necessary to request support from IT staff in order to set them up.
• They allow us to have the information that interests us most for daily operation and process optimization.
• They save money and time in product development.
3.-Robot control via PLCs
The modern components of these PLCs (chips, integrated circuits) give them extraordinary processing power.
• There is mid-range PLC equipment currently available that can handle up to 32 axes, which can be translated into the control of five robots with six axes each.
• There are dual ethernet ports to facilitate ring type topologies.
• Many screens already incorporate a web connection, so with a simple configuration we can access the robot's operation console from any mobile device.
4.-Operator safety
They comply with SIL2 and SIL3 (Safety Integrity Level) for safety applications in machinery.
This makes it possible to guarantee that the risks posed by the equipment to people, the environment and machinery have been reduced to the lowest possible level.
Some four or five years ago there were very few companies that had this certification; however, today it is almost standard in PLCs.
• Reduces risk in everyday equipment operation for the worker.
• SIL-certified equipment has redundant (duplicated) CPUs that separate risk functions from ordinary ones.
• There are inputs and outputs capable of handling redundant channels according to the case.
• Programming with certified functions in emergency shutdowns, safety curtains, etc.
• Security with powerful encryptions that help prevent possible hacks.
5.-‘The time traveler’
This tells us what was happening in the system logic when an error occurred in the process. This is possible thanks to an integrated video camera with an internal recording of the actions in the PLC.
• Allows the user to ‘go back in time’ to reproduce the recording of the failed process and see what the PLC was doing at that instant.
• Makes fault analysis easier and helps find solutions quickly.
