Regarding the issue of the “values” displayed on the DCs screen being taken from the real-time database?
Thread Content
The pressure, temperature, etc., displayed on the DCS have an actual \"point address,\" similar to an \"ID card\" for those values. By knowing this \"point address,\" I can transfer the DCS data to a real-time database. But for some points, such as those displayed on the DCs, the values are calculated from other tag numbers; so why can’t their “point addresses” be obtained, and why can’t real-time data be transmitted? I’m confused about this question. Thank you all!
It doesn’t mention any system either. . . . . . . . . . . .
This is not difficult to achieve; just communicate with the manufacturer. From the perspective of computer storage and communication, the value you calculate is certainly stored in some storage space, and it must have an address; however, this address is not what you call a \"point address\", but rather an internal data storage address within the computer.
