Block Mode/MODE_BLK
Selection, display
Index: 5
Data type: DS-69
Access: auto, man, OOS
The Block Mode/MODE_BLK parameter is a structured parameter consisting of four
elements. The Analog Input Block supports the "Auto" (automatic), "Man" (value and status
of the OUT parameter can be specified directly by the operator) and OOS (out of service)
modes.
TARGET
• Change the block mode.
ACTUAL
• Displays the current block mode.
PERMITTED
• Displays the modes supported by the block.
NORMAL
• Displays the block mode during standard operation.
Block Error/BLOCK_ERR
Display
Index: 6
Data type: bit string
Access: read only
Displays the active block error.
Possibilities:
• Out of service (OOS):
– The Analog Input Block is in the OOS block mode.
– The Resource Block is in the OOS block mode.
• Simulation active: DIP switch 2 "Simulation" on the electronic insert is set to "on", i.e.
simulation is possible.
– The simulation mode for the Analog Input Block is active. → ä 95, parameter
description for Simulate/SIMULATE.
– The simulation function is switched on in the Diagnostic Transducer Block. → ä 90,
parameter description for Simulation Mode/SIMULATION_MODE.
• Input failure: The input value transmitted by the Pressure or DP Flow Transducer Block is
not valid (BAD status). This could be due to the following:
– The Pressure or DP Flow Transducer Block is in the OOS block mode.
– A device error is present. In the Diagnosis Transducer Block, the Alarm Status/
ALARM_STATUS parameter (→ ä 90) displays an error code. → See also these
Operating Instructions, Section 12.1 "Messages".
!
Note!
The "Input failure" block error is relayed to downstream function blocks or high-order
process control systems by means of the BAD status of the output value of the OUT Analog
Input Block.
• Block configuration error: There is a configuration error in the Analog Input Block. This
could be due to the following:
– By means of the Transducer Scale/XD_SCALE parameter, a unit was selected that does
not suit the input value configured in the Channel/CHANNEL parameter.
– No valid input value was selected by means of the Channel/CHANNEL parameter.
→ ä 96, parameter description for Channel/CHANNEL.
– An unsuitable linearization mode was selected by means of the Linearization Type/
L_TYPE parameter. → ä 97, parameter description for Linearization Type/L_TYPE.
– The "Direct" linearization mode was selected by means of the Linearization Type/
L_TYPE parameter. The scalings for the Transducer Scale/XD_SCALE and Output
Scale/OUT_SCALE parameters do not match.
– If you assign the same process variable, such as "Primary value", to two Analog Input
Blocks, the same scaling values and units have to be set for both blocks.
Process Value/PV
Display
Index: 7
Data type: DS-65
Access: read only
The PV parameter is a structured parameter consisting of two elements.
VALUE
• Displays the process variable used for block execution
STATUS
• Displays the status of the process variable.
!
Note!
The unit used by the Output Scale/OUT_SCALE parameter is accepted.
