4.6 Transducer Block (TB)
The following tables list the Transducer Block parameters in alphabetical order.
It describes characteristics of the sensor output functions required to read the measurement
value from the Function Blocks.
The following tables contain short parameter description, factory settings (Initial Value (IV)) and
possible settings.

ALERT_KEY ALERT_KEY ALERT_KEY ALERT_KEY
Alert Key Alert Key Alert Key Alert Key
RW The identification number of the plant unit. This information
may be used in the host for sorting alarms, etc.

BLOCK_ERR BLOCK_ERR BLOCK_ERR BLOCK_ERR
Block Error Block Error Block Error Block Error
R This parameter reflects the error status associated with the
hardware or software components associated with a block. It
is a bit string, so that multiple errors may be shown.
Other
Setting:
• Other: Non-specific error active
• Block Configuration: Error detected in block configuration
• Link Configuration: Error detected in link configuration
• Simulation Active: Simulation enabled in this block
• Local Override: Output tracking of faultstate active
• Device Fault State: Device faultstate set
• Device Maintenance: Device needs maintenance soon
• Input Failure: Process variable has bad status
• Output Failure: Failure detected in output hardware
• Memory Failure: Memory error detected
• Lost Static Data: Static parameters cannot be recovered
• Lost NV Data: Non-volatile parameters cannot be
recovered
• Readback Check: Failure detected in READBACK
• Maintenance Needed: Device NEEDS maintenance NOW
• Power Up: Recovery from power failure
• Out Of Service: Block actual mode is out of service
MODE_BLK MODE_BLK MODE_BLK MODE_BLK
Block Mode Block Mode Block Mode Block Mode
The actual, target, permitted and normal modes of the block.
TARGET
Target
R/W This is the mode requested by the operator. Only one mode
from those allowed by the permitted mode parameter may be
requested.
Auto
Setting:
Auto / OOS
ACTUAL
Actual
R This is the current mode of the block, which may differ from
the target based on operating conditions. Its value is
calculated as part of block execution.
Auto
Setting:
Auto / OOS
PERMITTED
Permitted
R/W Defines the modes which are allowed for an instance of the
block. The permitted mode is configured based on application
requirement.
