Naming Requirements for Panel Board Tests

Do not use the same names for panels and boards. This is to ensure that software such as datalogging can process the data correctly.

Because the software expands node and device names by adding prefixes to them, choose node and device names that, when expanded, are not longer than allowed. Table 1 shows the number of characters in the prefix that the software adds to the device and node names.

Table 1    Characters added to device and node names

Number of Boards in Panel	Number of Characters in Longest Prefix
From 2 to 9	2
From 10 to 99	3
From 100 to 256	4

Devices tested with part libraries (e.g. resistor packs) have even more characters added to their device names. Dual-Well Shared Wiring includes additional prefix characters. Take this into consideration when choosing device names.

Table 2 shows the maximum number of characters (including prefix) allowed for device and node names.

Table 2    Maximum lengths for device and node names

Name	Maximum Length
Node name	40
Device name	48
Boundary-scan device name	20
