affect a change in Chinese

The allowable interactions between the DCS and SIS are Force,Local Override,Write and Release.In all cases the SIS is requesting the DCS to change a parameter value in order to affect a change. The SIS can request three types of changes: 1. Force a change to a DCS parameter. 2. Force a PID controller to Local Override. 3. Write to a DCS parameter. The allowed interactions between DCS and SIS are: Force, local bypass, write and read. In any case, the SIS may require the DCS to change parameter values ​​to accommodate the changes. SIS can require the following three changes:: 1. Force DCS parameters to change 2. Force PID controller to bypass locally 3. Write DCS parameters

Correction, I just saw another post, released should mean released, not "read out"”

affect a change------> to adapt to the change----->to accommodate a change :o :o :o

I used an extended meaning:P The meaning here is obviously that the DCS and SIS systems make corresponding changes in response to previous changes in process conditions to affect the final results. I think the author who wrote these things may not be a native English speaker, so many of the words and expressions are strange. What we have to do is to express the correct meaning, which may involve integrating some of our own craft experience. As the old saying goes, not every word may match, but the meaning must be correct.

What does change in to affect a change mean? Does it mean changes in process conditions? Or does it refer to DCS parameter changes? If translated, the following also makes sense. the SIS is requesting the DCS to change a parameter value in order to affect a change. SIS requires DCS to change parameter values ​​to produce changes.

We have different ways of segmenting sentences, hey, my method of segmentation is: the SIS is requesting the DCS to change a parameter value in order to affect a change.

in order to (in order to, so that,....) effect a change, or still can't understand what the author wants to say? Poor background knowledge in instrumentation and control.

Affect a change should produce a change, so that it corresponds to the three changes in the next sentence. In addition, Override means that when the automatic control system receives abnormal signals such as accident alarms, deviation limits, and failures, the override logic will immediately execute logical functions such as automatic manual switching, priority increase, priority decrease, prohibition of increase, prohibition of decrease, etc. according to the cause of the accident, and the system will be converted to a preset safe state and an alarm signal will be issued.

Affect a change, this change should refer to a change in process. In the past two days of following, I have gradually learned more and more about this SIS system, haha. If a fault occurs, some process parameters will change. At this time, the SIS system will operate better than the DCS to adjust the working conditions. Try to translate it as: Used for working condition adjustment.

I'm really impressed that you can understand this SIS system from the limited posts I posted. After I finished the translation, I proofread it twice and still wasn’t very clear about what I translated. This may be the difference from professional and technical personnel.

Of course, the SIS still needs to be controlled through the DCS, but it must send control instructions and signals prior to the DCS. For small adjustments during normal operation, the operator operates through the DCS. When there is a large fluctuation in the working conditions and the operator is too busy, the SIS control system starts to act and takes precedence over the DCS action and adjusts to stabilize the working conditions, and then hands it to the operator to operate using the DCS. SIS is also controlled by program logic (PLC). The programs are written in advance. When the conditions are met, the program starts to take effect, such as where to open the vent and how much to release, how much to reduce the system load, etc. When these actions are completed, the SIS system is handed over to the operator for DCS operation. In this way, the entire production line of the device will not be stopped, and the stopped part can be quickly opened. The most important thing is that it can reduce the operator's misoperation.

The allowable interactions between the DCS and SIS are Force,Local Override,Write and Release.In all cases the SIS is requesting the DCS to change a parameter value in order to affect a change. The SIS can request three types of changes: 1. Force a change to a DCS parameter. 2. Force a PID controller to Local Override. 3. Write to a DCS parameter. Allowed interactions between DCS and SIS are forcing, local override, setting and unsetting. In all cases, the SIS requires the DCS to change parameter values ​​to produce changes. SIS can request three types of changes:: 1. Forcibly change DCS parameters. 2. Force the PID (proportional-integral-derivative) controller to local override. 3. Set DCS parameters.

Agreed, "produce a change", I originally understood it to mean making the change take effect (affect is roughly understood as effect), but the meaning is roughly the same. :lol
