Not that I know of. Sometimes displays are built into the control room's wall, sometimes they are entirely on a computer screen. ESDs are accessable anywhere within what could be many drill-down screens each showing increasing levels of detail of individual sub-systems. As you drill down, you may only have access to the general ESD shutdown and the shutdown controlling the particular subsystem you have up at the time.
The overall screen will have the general shutdown prominently displayed and possibly all local shutdowns too, each local shutdown contained within a smaller box devoted to the particular subsystem, but not always. Sometimes you have to drill down to the subsystem to remotely activate that subsystem's ESD. Just depends on how you want to write your SCADA spec. I think its a good idea to have access to all shutdowns from the overall screeen, but sometimes a whole system is too complicated to display each and every shutdown on the overall display. In that case, you may have access to the primary facility shutdown and ESD valves on the overall, and have to drill down to get access to subsystems within that facility, such as an ESD for the one pump area only and a separate ESD for another pump area, an ESD for lines going to the tank farm, etc.
Typically the SCADA vendors have a customary way of making their particular displays, if the owner does not have a particular way they want it done, most somewhat similar, but they can vary from vendor to vendor. Then again, some companies have standards to show open valves green and closed valves red, opening valves blue and closing valves yellow, some companies like the reverse, some companies use a flashing color to indicate a changing valve position. Some companies like to see their running pumps red and their stopped pumps green, I like the reverse.
I do not like to see a remote control to open an ESD valve via SCADA, unless you get a local OK too.
