38
between the frames 38 and 39 is that the later accomodates for 12
bit analog values for the sensor sampling inputs and 16 bit
counters for the pulse counter inputs. In addition, the correspon-
dence between input analog and digital ports and their position in
the frame differs.
The composition of the data block of a frame type 38 (the bytes
marked as d1, d2... dn) is depicted in Figure 9, a type 39 frame in
Figure 10 while the digibyte is depicted in Figure 11 and
Figure 12.
