4.5 Analog Input Block (AI 1...4)
The following tables list the Analog Input Block parameters in alphabetical order.
It describes characteristics of the measurement values obtained from the Transducer Block in a
user defined way and to deliver it to the control system. There are also some parameters in the
Analog Input Block, that can be configured to get a measurement value quality as desired by the
user.
The following tables contain short parameter description, factory settings (Initial Value (IV)) and
possible settings.

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.

• 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
