Parameter
Data type
Description
Possible values
xPS
BOOL
Voltage source (Power Source)
FALSE
Unit is supplied via Aux.
TRUE
Unit is supplied via AS-i.
xPM
BOOL
Power24-Modul (PM)
FALSE
Power24 module missing.
TRUE
Power24 module is inserted.
xEF
BOOL
Earth fault
FALSE
No earth fault
TRUE
Supply voltage is asymmetric,
earth fault suspected.
xSE
BOOL
Status of the earth fault detection
FALSE
Earth fault detection does not
provide valid data (e.g. when
AS-i voltage is lacking).
TRUE
Earth fault detection provides
valid data.
xPF1
BOOL
Voltage <22.5 V (power fail 22.5 V)
FALSE
No AS-i power fault (Classic
APF)
TRUE
AS-i power fail (Classic APF),
i.e. AS-i voltage is below
22.5 V
xPF2
BOOL
Voltage <19.0V (power fail 19V)
FALSE
No AS-i power fail (24V-APF)
TRUE
AS-i power fail (24V-APF), i.e.
AS-i voltage is below 19.0 V
wVoltage1
WORD
Voltage AS-i+ to AS-i- in mV
wVoltage2
WORD
Voltage FE to AS-i in mV
iSymmetry
INT
Symmetry in % (-100% ... +100%)
0xFF9C
...
0x0000
...
0x0064
-100%
...
0%
...
+100%
xReady
BOOL
Signal indicates if the execution of the
FB is terminated.
FALSE
FB is inactive or being
executed.
TRUE
FB execution is terminated.
xBusy
BOOL
Signal indicates if the FB is executed.
FALSE
FB is deactivated or FB
execution is terminated.
TRUE
FB execution is started but not
yet terminated.
xError
BOOL
Signal indicates if errors occurred
while the FB was executed.
FALSE
FB is disabled or presently
executed or FB was executed
without error.
TRUE
An error occurred when the FB
was executed.
