1.3.2 Connected Extension Units/Blocks
The table below shows extension units/blocks and their data lengths when connected to a
32DP-IF. Data is exchanged between the 32DP-IF and DP-master during every cycle. The
maximum amount of data that can be exchanged with the 32DP-IF is 200 bytes of input data
and 200 bytes of output data. Please check the specification of the DP-master, it may limit the
total amount of exchanged data.
*1 Total 8 bytes, selection between averaged data (BFM #5 ~ #8) or present data (BFM #9 ~
#12) can be done by GSD file configuration for each channel separately.
