The actual state of a point can be referenced in a script by putting an S before the point. Actual state is either
ON/ALARM/ACTIVE or OFF. The S operator should be used when the isolated state of the point is to be ignored
and only the on/off state is required. Using the S operator before the point will return the actual state of the point
and ignore the fact that the point is isolated.
E.g. If L1D1 is in alarm and isolated it would normally be treated as off, all isolated points are treated as off or
inactive in scripts. Script "SL1D1;" will activate its associated output if L1D1 is in alarm and isolated but script
"L1D1;" will only activate its associated output if L1D1 is in alarm and not isolated.

Combination examples:
Example
(1.1.z1 or 1.1.z2) and !1.1.z3;
(1.1.i1 -> 1.99.i3) or (1.1.z1 -> 1.99.z8);
CA and T10;
(ANY3[Z20] or Z21) and !VP10;
Caution:
When a script is being evaluated and a point in the script is found to be isolated, that point is treated as being
inactive (i.e. off or non-alarmed). If the NOT function has been used in the script, this may have unexpected
results. For example, a script such as 1.2.o3 = !1.3.I4; would operate as follows: output 1.2.o3 is ON when
input 1.3.I4 is OFF, and the output 1.2.o3 is OFF when input 1.3.I4 is ON. However if input 1.3.I4 is now
isolated, output 1.2.o3 will go ON because the script will treat the isolated point as OFF (inactive). This may
or may not be the desired action depending on the application.
Note:
Special Netpoints can be used to perform special functions on AFP-2800/2802 FIP. See page 90 for details.
