HART VARIABLES
QV (quaternary variable) Not used
The Flowrate value is permanently linked to the PV and the analog output.
Device status information
The E018-P returns its status in the device status byte available through command 48. When the
status flag ‘more status available’ is set, command 48 can return the following status flags in its
additional status bytes:
DEVICE STATUS INFORMATION
B YTE D ESCRIPTION C ONTENT
14 E0 error register 1 Fld. Dev.stat 14-1 0x01 Display error
Fld. Dev.stat 14-2 0x02 EEPROM error
Fld. Dev.stat 14-3 0x04 Not used
Fld. Dev.stat 14-4 0x08 Not used
Fld. Dev.stat 14-5 0x10 Low alarm error
Fld. Dev.stat 14-6 0x20 High alarm error
Fld. Dev.stat 14-7 0x40 Linearization error
15 E0 error register 2 Fld. Dev.stat 15-1 0x01 Initialization error
Fld. Dev.stat 15-2 0x02 Warning: Total was cleared (either
via HART or by hand)
FLD. DEV.STAT 14-1 and FLD. DEV.STAT 14-2 are critical errors.
The device malfunction flag is set in device status.
The device malfunction is not shown with Namur43-conditions but with a status flag in the device
status through command 48.
Command specific response codes
The following response codes are valid for all implemented commands:
COMMAND SPECIFIC RESPONSE CODES
C ode C lass D escription
0 Success No command-specific errors
1 - Undefined
2 Error Invalid selection
3 Error Passed parameter too big
4 Error Passed parameter too small
5 Error Too few data bytes received
6 Error Device-specific command error
7 Error In write protect mode
Units
The predefined units in HART are mapped to the E018-P totalizer and flowrate units as follows:
