a,b,c,d,e,f,m, n = Constants (settings)
x = Input value
y = Output value
In equation mode, the WARNING output goes high when large output value numbers, typically above
8388607 (absolute), are rounded to the last decimal point.

10.2.2
Functionality
The Double point indication status times DPISTTIM function computes the status times of a double
point indication (DPI) by counting the times since the last status changeovers. The inputs for this
function are two boolean signals of a DPI. The outputs provide the time either in milliseconds,
seconds, minutes, or hours from the last status changeover. DPISTTIM function can be used for
computing the idle times, that is, time since the last open and close operations of a switch.
Technical Manual
If x is large and m, n, e are not set to small values, the output will overflow. Similarly,
if x can be negative then m and n must be natural numbers.
ANSCAL status output signals
Description
Combined warning signal, TRUE (1) on any of the following conditions:
•
In Chart mode, when the input signal is inside the permitted range but outside the
compensation range (see
•
In Equation mode, if the absolute output value is too large to ensure full numerical
accuracy
Combined alarm signal, TRUE (1) if any of the following conditions is detected:
•
Faulty sensor
•
Settings X for curve point input values in Chart mode are out of sequence
•
INPUT value is lower than LowLimit or higher than HighLimit
•
BLKFUNC input is 1
Sensor status output for IEC 61850 reporting purpose:
TRUE (1) – Sensor status is unhealthy
FALSE (0) – Sensor status is healthy
