Exida has determined through extensive analysis of SLATE that it demonstrates exceptional work and has the ability to play a key role in making the world a safer place.Limit input can handle up to two safety, dual sensor system inputs or combination of a single dual sensor input and multiple analog IOs.Limits can be configured to recycle andor lock out either via contact or com bus.Multiple analog IOs can handle a combination of at least 12 sensors, andor analog IOs programmable per wiresheet (logic).
This single burner system is ideal for applications requiring a high level of IOs. The analog capability enables leadlag logic as well as basic boiler IOs such as temp inputs, feedback loops, and throttling control. Geneva06Basic for dual fuel applications requiring low NOx, tight control of combustion mix with O2 trim and safety sensors and programmable logic. Thats why, for us that works with SCADA systems, its essential to be familiar with the older systems. It is widely used in factories to monitor and control production lines and machines. A good way to make an understanding, of what a SCADA system is and where it can be used, is to see it in relation to the automation pyramid. The automation pyramid is a concept published in ISA-95 and IEC 62264-3, in an attempt to describe how different systems work together. At the top you have all the information systems for handling business, planning and logistics. And at the bottom you have all the operational systems. SCADA systems are placed right in the middle of the automation pyramid. Right where IT (information technology) meets OT (operational technology). The job of SCADA is really to control and monitor all this OT. But at the same time also to send and receive information from the MES or ERP system above. The SCADA basics is really about exchange of information and the ability to control and monitor. Especially the latter is how you will often see SCADA systems in use. More than often multiple screens where an operator can both control and monitor all relevant components in a unit, machine or even a whole plant. This could be visualized with e.g. PID (piping and instrumentation diagram). Back in the days an HMI was really just a bunch of push buttons and control lamps. But now you will often have a touch screen either at the machine or in a control room. Because where the HMI is just the screen or the interface itself, SCADA is an application or a whole system behind all those screens. A SCADA system can have many HMIs to control and monitor different parts of a plant. It is a whole infrastructure of devices that can communicate. Clients like desktop computers and screens can then function as HMIs by connecting them to the server. Since the operational devices like PLCs and RTUs are also connected to the server, we can now use the SCADA clients to control and monitor operations. You can connect sensors to the RTU and it will convert their signals to digital data. This digital data will then be available for the SCADA system. How SCADA has developed from a simple monolithic architecture to cloud based infrastructure. But even though the fourth generation of SCADA systems has arrived, many of the existing systems still belong to the third or even the second generation.
