Detailed information
bit 0 to bit 7 of the HART field device status are turned on,
and any of the following statuses occurs.
■Primary variable out of limits
The PV value is out of the operation limit range.
■Non-primary variable out of limits
The SV, TV, or QV value is out of the operation limit range.
■Loop current saturated
Current has reached the upper or lower limit and cannot
increase or decrease.
■Loop current fixed
The current value is fixed.
■More status available/unavailable
The added status information includes diagnostic
information.
■Cold start
The HART-enabled device has been powered off or reset.
■Configuration changed
The settings of the HART-enabled device have been
changed.
■Device malfunction
Because a serious error or failure has been detected in a
HART-enabled device, the HART-enabled device is not
properly operated.
bit 9 to bit 14 of the HART field device status are turned on,
and any of the following statuses occurs.
■Buffer overflow
A message to the HART-enabled device is too long for the
receive buffer.
■Communication failure
The communication has failed.
■Longitudinal parity error
The longitudinal parity calculated by the device is not
matched with the message check byte.
■Framing error
A stop bit of 1 byte or larger is not detected.
■Overrun error
The data of 1 byte or larger in the receive buffer is
overwritten before read.
■Vertical parity error
The parity of one or multiple bytes received is not odd.
