What symbol is the “R in a triangle” in a PID diagram?

Does anyone know what symbol the “R in a triangle” is in a PID diagram?
I searched for the PID for ages but couldn’t find the symbol mentioned by the original poster...
Generally, R is used as the initial letter to denote radioactivity, and as a subsequent letter to denote printing or recording. It is suggested that the poster post a screenshot for reference.
It indicates that this place has been modified, meaning Revised. It is also expressed as R1, R2, meaning revision 1 and revision 2.
In a triangle, R denotes the modified portion, not a graphical symbol in a flowchart.
In the drawing standards, there is no symbol for this triangle
Are they foreigners’ drawings? Should the R version indicate the changes here?
It is a marker indicating the modifications made on the original version; R1, R2, and so on denote the first modification, the second modification, and so on.
It is the RESET signal sent to the DCS from the instrument: lol
In a PID diagram, the symbols inside the “triangle” (usually 0 or 1) generally represent the version number; it indicates on which version changes were made. R denotes modifications made based on the existing version.
Foreigners generally use drawings* in this way to indicate that a certain part has been modified; if it’s version 1, then there is a ‘1’ inside a triangle
Yes, this R probably means Revision, that is, the version; usually it’s the PID created by foreigners
It should indicate the meaning of modification. Such a mark is present on the compressor drawings in Kobe, Japan
