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

R/W This is the mode requested by the operator. Only one mode
from those allowed by the permitted mode parameter may be
requested.
OOS
Setting:
Auto / Man / OOS

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.
OOS
Setting:
Auto / Man / OOS
PERMITTED

R/W Defines the modes which are allowed for an instance of the
block. The permitted mode is configured based on application
requirement.
Auto, Man and OOS

Auto / Man / OOS
ST_Rev ST_Rev ST_Rev ST_Rev
Static Revision Static Revision Static Revision Static Revision
R The revision level of the static data associated with the
function block. The revision value will be incremented each
time a static parameter value in the block is changed.
