IF2030/PNET
The write and read commands, see
, belong together. The write command
WRREC
that is used to send the command to the
IF2030 is executed first. IF2030 forwards the command to the sensor. IF2030 immediately notes the sensor answer in a buffer. On the
SPS
RDREC
is executed and thus the last command and the answer buffer are read back at the same time; the answer from IF2030 is
saved in the RECORD buffer.
Fetch answer, see
This chronology is a reaction to the prior write command, see
.
