Table 9.20 lists the complete output object references. Use the relative indices
from Table 9.19 to determine specific bit locations within the Table 9.20 port-
specific control point index ranges (8–83, 84–159, etc.). For example, to
determine the index of the SRB10 bit on Port 3, first find the Port 3 Index
Range in
Table 9.20 (236–311). Then, get the Relative Indices of SRB1–
SRB16 from Table 9.19 (28–43). Now you can calculate that Port 3 SRB10
has the relative index of 37 (28 + 10 - 1), and its absolute index is 273 (236 +
37). Objects 8–83 are unique from other objects because the actual port being
mapped to is determined by the analog output object. This yields two ways in
which binary output objects can be operated: directly using indexes 0–7 and
84–1451 or by reference by writing to analog output object 0 and binary
output object 8–83 at the same time. For the example above, you can either
write the desired output value to index 273, or simultaneously write a 3 to
analog output object 0 and the output value to binary output object 37. The
bits can only be read by first setting the analog output object to select the port
data to read.
