6.4.5 Sensor error
A sensor error occurs when the output signal generated by the measuring device lies outside the
normal operating range of 4 mA to 20 mA. The Web server responds to this condition by displaying
ERROR or WARNING as device status. An e-mail is sent only when the device is in ERROR
condition and the Alarm Mail box in the Sensor Error dialog has been checked, see Table 6-11.
Table 6-11: Behaviour of device status and limit status for measured values outside range limits
The sensor error setup dialog for a HART device is shown below. The significance of the parameters
is described in Table 6-12. For analog and binary devices, only the first line appears.

Use CMD48 for
extended device
status
Click the box to read the Extended Device Status (HART Command 48, every 10th update time)
– The Extended Device Status is a 0 to 10 byte data field that contains coded information
describing the device status.
– It is not standardized and varies from device to device, see device manual.
Extended device
status
Read-only value showing Extended Device Status
– OK - device OK, WARN - device warning, ERROR - device error
Error bitmask
CMD48 (hex)
Bit mask that corresponds to the error you wish to detect, see device manual
– Used only if CMD48 is enabled
Warning bitmask
CMD48 (hex)
Bit mask that corresponds to the warning you wish to detect, see device manual
– Used only if CMD48 is enabled
