Parameter
Description
Event log lockable
If clear, the event log behaves as a FIFO buffer; a new record
overwrites the old one even if the overwritten event has never
been downloaded, in which case, the event is permanently
lost. If set, and the log is full with never downloaded events,
then the log is locked. Controllable events (changes to most
datum points) are not allowed to occur. Non-critical, non-
controllable events (e.g. checksum alarms) are discarded and
are permanently lost, and critical non-controllable events (e.g.
PLC mode change) are written as usual and the overwritten,
never downloaded events are permanently lost. A locked log
must be downloaded to unlock it for normal behavior.
Barometric pressure in psia
If set, the barometric pressure will be expressed in psia units,
otherwise it will use kPaa.

Configuring Pass-Thru Options
The Pass-Thru feature can be used for delivering data written packets directly to the
PLC logic, bypassing the MVI56E-
AFC’s or MVI69E-AFC’s Modbus database. For
details on configuring this option, please refer to the
AFC Reference Guide
