Figure 4.23
As was stated earlier in chapter 3 each of the assembly structures are twenty members long with each
coming from the factory with a default configuration (Table 3.6 & 3.7). Any of the twenty members can be
changed to your liking. As an alternative to modifying the assembly structures any given parameter can be
read or written to using explicit messages as was done in figure 4.22.

Figure 4.24 below shows the configuration screen for MSG instruction in figure 4.22. Notice that the in-
struction is looking for Hex characters for the class, and attribute fields. As shown below, 77h (Class) equals
119d, 2d (Instance), 3h (Attribute). The source element is shown above in figure 4.23 where one can see that it
is configured as a SINT with each byte corresponding to the CIA.
Figure 4.25 is the last piece of the puzzle. Click the browse button and find and select your device. After
doing so, enter a comma and a space, followed by the port number (2), and then lastly, the device node ad-
dress.
