Binary input
issued in the BINARY_INPUT2 parameter
of the AO Transducer Block.
−
Internal solenoid valve
In this setting, the current switching state
of the optional internal solenoid valve is
analyzed and issued over OUT_D. '0' in-
dicates a de-energized solenoid valve (U
< 15 V DC) and '1' an energized sole -
noid valve (U > 19 V DC).
− Discrete final valve position
In this setting, the current discrete valve
position is issued over OUT_D. The val-
ues are assigned as follows:
0
Device not initialized
1 Valve closed
2 Valve open
3 Valve in intermediate position
−
Condensed state
In this setting, the current condensed
state according to NAMUR Recommen-
dation NE 107 is issued over OUT_D.
The status messages are assigned to the
discrete value as follows:
0
No message
1 Maintenance required
2 Maintenance demanded
3 Maintenance alarm
7 Function check
− Condensed state and VST
The positioner starts a single partial
stroke test. The test is performed using
the settings in Code 49 - d2 to Code 49
- d9 (see section 5.4).
Additionally, the condensed state ac-
cording to NAMUR Recommendation
NE 107 is issued over OUT_D. The status
messages are assigned to the discrete
value as follows:
0
No message
1 Maintenance required
2 Maintenance demanded
3 Maintenance alarm
7 Function check
The logic state of the binary input is defined
in the 'Configuration binary input 2' param
-
eter (CONFIG_BINARY_INPUT_2).
