Revisions of positioner firmware in comparison to previous versions
Previous New
Communication K 1.11 K 1.21
Leakage sensor at binary input 2 The connection of a leakage sensor at binary input 2 (by selecting
LEAKAGE SENSOR in CONFIG_BINARY_INPUT2 parameter of
the AO Transducer Block) causes:
4
Information specified in XD_ERROR_EXT parameter in the AO
Transducer Block and the generation of a diagnostic alarm
which is logged
4
The state of the binary input is reported in BINARY_INPUT2
parameter in the AO Transducer Block
Diagnostic alarm
“Device not initialized“
The diagnostic alarm “Device not initialized” is generated when
the positioner is not initialized and the condensed state is set to
“Maintenance alarm”.
Display of the operating range
FINAL_VALUE_RANGE
The correction of the operating range FINAL_VALUE_RANGE
over on-site operation of the positioner (Code 8/9) is also trans-
ferred over fieldbus in firmware version K 1.21 and higher.
Inactivated internal solenoid valve A masking allows to set whether an inactivated internal solenoid
valve generates an AO block error, resulting in a block alarm.
SOLENOID_SELECT parameter The SOLENOID_SELECT parameter in firmware K 1.21 and
higher allows to set whether a “Maintenance now“ block error of
the AO Transducer Block results in an output error in the AO
Block.
TOT_VALVE_TRAV_LIM parameter New range: 1000 … 990 000 000
K 1.22
Operating range
FINAL_VALUE_RANGE
The operating range FINAL_VALUE_RANGE of the AO Trans-
ducer Block is compared on entering it with TRANSM_PIN_POS.
If the TRANSM_PIN_POS parameter is changed, the positioner
checks whether the setting and unit match the current operating
range FINAL_VALUE_RANGE. If this is not the case, the
FINAL_VALUE_RANGE parameter is set to 0 to 100 %.
VALVE_TYPE parameter The parameter of the AO Transducer Block is set depending on
the selected PIN_POS. The last setting is kept when VALVE_TYPE
is set to OFF.
FINAL_VALUE parameter The output value is scaled with FINAL_VALUE_ RANGE in firm-
ware K 1.22 and higher, and not as previously with XD_SCALE.
Display of O/S mode in
AO Transducer Block
If the AO Transducer Block is set to O/S mode, this is indicated in
the positioner display by MAN/AUTO.
