WY. Posts: 61 Rating: (0)	Dear Support, As for the WinCC V7.5 or others, I would like to know the principle or method how they calculation and the tag meaning. Below my WinCC record and there are about 1500 tags. @prf_dmrt_chncon_xxx_tag_read_bytes_per_second - 8.928571429 @prf_dmrt_chncon_xxx_tag_read_bytes_total - 59668 @prf_dmrt_chncon_xxx_tag_reads_pending - 0 @prf_dmrt_chncon_xxx_tag_reads_per_second - 5.952380952 @prf_dmrt_chncon_xxx_tag_reads_total - 28158 @prf_dmrt_chncon_xxx_tag_writes_pending - 0 @prf_dmrt_chncon_xxx_tag_writes_per_second - 0 @prf_dmrt_chncon_xxx_tag_writes_total - 1 @prf_dmrt_chncon_xxx_tag_written_bytes_per_second - 0 @prf_dmrt_chncon_xxx_tag_written_bytes_total - 255 Refer to the first tag, it shows 8.9. Is it 1 second only read 8.9 byte data? Is it depend on what grahpic is opening which make different performance tag result?
