4.3. Universal Card Parameters
The following registers provide basic information about each node/module installed. Most parameters contain 21 entries,
with each entry corresponding to an installed node (entries 1 through 20) or module (entry 21 corresponds to the
WattsOn-MCM-V). Most entries contain only 1 register, but some contain more than one. If a node is not installed, it will
return 0 (for signed and unsigned integers), the null character (for strings), or QNaN (for floating-point values).
For example, to read the Card Serial Number of the node installed in slot 5, read registers 0x47C8
– 0x47C9,
which is: ½RegisterLength * (NodeSlot – 1)), or (2 * (5 – 1)) in this case. Because it is a
2-byte register, both 0x47C8 and 0x47C9 must be read (0x47C8 is the most significant word).
