84 Channel Configuration, Data, and Status

Input Type Status (Bits 0…3)

The input type bit field indicates what type of input device you have
configured for the channel. This field reflects the input type selected
in bits 0…3 of the channel configuration word when the channel is
enabled. If the channel is disabled, these bits are cleared (0).

Data Format Status (Bits 4 and 5)

The data format bit field indicates the data format you have defined
for the channel. This field reflects the data type selected in bits 4 and
5 of the channel configuration word when the channel is enabled. If
the channel is disabled, these bits are cleared (0).

Broken Input Status (Bits 6 and 7)

The broken input bit field indicates how you have defined the
channel data to respond to an open-circuit or short-circuit condition.
This field reflects the broken input type selected in bits 6 and 7 of the
channel configuration word when the channel is enabled. If the
channel is disabled, these bits are cleared (0).

Temperature Units Status (Bit 8)

The temperature units field indicates the state of the temperature units
bit in the configuration word (bit 8). This feature is only active for
RTD input types with the channel enabled. This bit is cleared (0) if the
channel is disabled or if the input type is a resistance device such as
potentiometer.

IMPORTANT

The status bits reflect the settings that were made in the configuration
word. However, two conditions must be true if the status reflected is to
be accurate.

• The channel must be enabled.

• The channel must have processed any new configuration data.
