When configuring the point database, there are several rules that must be followed:

•No two points within a channel’s point list may have the same pn number.

•Pn numbers can be between 1 and 65535 (1 - 0xFFFF hex).

•Sn numbers can be between 0 and 65535 (0 - 0xFFFF hex).

•Pn numbers 9998 and 9999 are reserved for Universal Access registers and therefore cannot be programmed as a point’s pn number. Refer to section 12.3.3 for more information.
