The MDSA will be displayed in the scanlist if it has been mapped correctly. Once you have
determined that the MDSA is mapped to the scanner, you must verify that you have mapped
the correct input and output assemblies. To verify that you have the correct input assembly,
select the
LQSXW tab on the above screen. The following screen will appear:
You can see that each byte is mapped to a certain address. For example, the above diagram
shows bytes 1 and 2 at I:1.1(the I indicates that it is an input and the 1.1 is the input address).
Verifying the Input Assembly
Compare the above screen to the input assembly that was chosen. For our purposes we will
compare the above screen to input assembly 105.
Note that input assembly 105 requires 8 bytes and that the assembly shown in the previous
screen has 8 bytes. If the size does not match, you will need to edit the I/O parameters. If
your assembly matches the input assembly seen in RSNetworx, you may skip to Verifying the
Output Assembly (page 4-6).
