Default Service Type
The default service type of these variables is
unacknowledged.
Analog Sensor Output – nvoAiValuePct[ ]
If configured for voltage input, this network variable output
represents the percentage level for the appropriate input.

Default Value
The default value is set after power-up or reset and remains
until the module has measured a valid value.
nvoAiValuePct = INVALID = 0x7FFF (=163.835%)
The sensor failure behavior can be configured for 2 … 10 V.
Temperature Sensor Output – nvoAiTempP[ ]
If configured for temperature sensor input (but not from
PT1000-2 temperature sensors), this network variable
output represents the temperature for the appropriate input.
Range: see Table 44 and Table 45 on page 40.
Default Value
The default value is set after power-up or reset and remains
until the module has measured a valid value.
nvoAiTempP = INVALID = 0x7FFF (= 327.67 °C)
Slow Digital Input – nvoAiSwitch[ ]
This network variable output represents a slow digital input
connected to the universal input terminals.

Temperature#2 Sensor Output – nvoAiTemp[ ]
If configured for temperature sensor input (from PT1000-2
temperature sensors, only), this network variable output
represents the temperature for the appropriate input.
Range: see Table 44 and Table 45 on page 40.
Default Value
The default value is set after power-up or reset and remains
until the module has measured a valid value.
nvoAiTemp = INVALID = 0xFFFF (= 6279.5 °C)
