Transducer electronic datasheet
TEDS data sheet
Syntax: TED p1,p2,p3(x)
Parameters:
p1 p2 P3 Effect
0 ­ ­ Reads in the TEDS data from the transducer to the
amplifier .
If the data are damaged or if TEDS is not available, we
have the response q1 = "?
"
. In this case, no TEDS data
are transmitted to the amplifier (length = 0).
If more than one TEDS transducer identification is read
out (PCS/SPS), the error response is also output if only
one TEDS transducer identification has a read error.
TEDS data are arranged in 32‐byte pages. The first
byte is the checksum, the subsequent 31 bytes are data
bytes. The data are read and checked until the first
invalid page is found, or all the pages have been read.
Valid data pages are stored in the amplifier. The
checksum bytes are removed.
The command is executed synchronously. This means
that the response is output, when the TEDS transducer
identification readout is concluded.
Virtual subchannels (channel 9) do not support TEDS
transducer identification (not physically present). The
readout is ignored, and OK is returned.
