Dear All,
I need your helps, please!
I have to conduct SP-PID preparation with some instrument requirements of Client. There are two points which I can not understand clearly as below:
1.Instrument tag numbering references.
2.Tag numbering for instrument function.
Take my attachment as an example,as my understanding, the first one is described for tag numbering references such as FT-201, FT-202, FV-201 etc.., and the second one is described for the function of instruments, e.g. FT- flow transmitters, FV- flow control valve, FE- Flow element. However, if so, the first one can cover the second requirement !?!
Could you please help me about it?
Thank you very much and have a nice day
