Does the Deltav controller need to download data after uploading it?
Thread Content
For Deltav’s DCS operating system, the process has modified the alarm values in numerous control panels, resulting in inconsistencies with the parameters in the program modules. If I perform an upload to the controller, do I still need to download it as well? ? ? If it’s the controller download, that won’t work. Since production is always in operation, I would like to ask the experts here for advice
Without knowing Emerson’s DCS, from a logical reasoning perspective, the alarm data is first modified on the workstation; this modification entails changing the database within the controller. Uploading refers to transferring these altered data to the engineer station, thereby updating the configuration files.
Ask the DCS engineers at your factory; each factory should have dedicated personnel for this task
Just upload it, and why is it allowed for the process to have the authority to modify alarms?
Honeywell requires uploading and downloading data, which is equivalent to the function of a CPU and server storage; otherwise, the data will be lost in the event of a power outage. It’s necessary to examine the logical relationships between the databases. Try to run it on the configuration software; it’s less likely to cause confusion.

Because, in a broad sense, Emerson can be understood as an online database, as well as an offline database. What you upload are the data from the controller; generally, for management purposes, we need consistency in the database. I suggest you search for “DeltaV video tutorials” on Taobao to improve your skills through these videos.
Honeywell and Emerson are pretty similar in that both meet the IEC61131 standards, and they both follow the American approach to programming and configuration. It is recommended that the original poster search for \"Honeywell PKS video tutorials\" on Taobao to improve their skills through these videos.
In the initial stage, it’s sufficient to upload the alarm values; there’s no need to download them again. Thank you all for your discussions. When uploading, it will ask whether to standardize different values of the module
