Why do some parameters of the DCS alarm function not have an alarm feature? How can I add the parameters I want to set for an alarm function?
Find an instrument to set it for you; it’s best not to touch the operations themselves
Find an instrumentation engineer and let a professional take care of it
During design, some parameters in the process need only be displayed to assist production operations, without the need for alarms or involvement in interlock functions, etc. If it is determined during production that a certain parameter is important, the instrumentation and control personnel can be asked to add alarms in the DCS. After all, the design institute is not omnipotent~~
It is recommended that the poster find an instrumentation technician; you just need to provide them with the points to be set and the alarm parameters.
It is available in the system configuration suffix table; you can’t modify it if you’re not an automation engineer. Find a professional from your factory.
Go to DCS and say you want a sound alarm; specify the value at which an alarm should be triggered, and have DCS set it up
The setting of DCS alarm parameters must comply with the requirements of process and instrument interlock control; alarm points cannot be set arbitrarily, especially those involved in process interlocks.
The corresponding settings are defined during configuration; for example, the setting for AI signals is either full or half second. The systems of different manufacturers vary slightly, and this should be possible by making adjustments to the configuration. However, it’s important to check whether interlocks are in place.
