I’ve seen an ESD system for a device that was standalone; I haven’t seen any others like that
You mean the output point, right? This can be displayed on the host computer
It can be displayed on the host computer
When working on projects, we usually integrate it into the DCS system for unified display.
Reply to 5# tiger.wang: ESD can be an independent system or integrated into the DCS, but in either case it can be displayed on the DCS. Most functions cannot be operated from the DCS; if it is possible to do so, it is recommended to create an MP panel that includes some of the important start-up and bypass buttons, as this makes it safer compared to using the DCS.
As a side note: 1. I’ve seen TRICON used in combination with INTOUCH. It is to use host computer software to display the control process. 2. Most ESDs do not have flowcharts. But there is a host computer. It can be used as an SOE record; the configuration screen can also be opened for online monitoring, as well as for forced input and output. 3. ESD can communicate with the DCS, and its status can be displayed on the DCS through soft points

It should be available for general engineering applications, allowing points within systems to communicate with each other and display data, which facilitates comparison between various stages of the process. It facilitates a more comprehensive comparison of the processes. However, for the display screens, this is generally not the case; we add the graphics that are required by the manufacturing process during the post-maintenance phase, and these graphics are then displayed on the DCS or ITCC screens
In fact, all this work is done for the operators and the manufacturing process; what suits one’s own needs is what’s good, and it depends on one’s own understanding.
