Memory Module
Information Function
File
The controller has a Memory Module Information (MMI) File which is
updated with data from the attached memory module. At power-up or on
detection of a memory module being inserted, the catalog number, series,
revision, and type (memory module and/or real-time clock) are identified
and written to the MMI file in the user program. If a memory module and/
or real-time clock is not attached, zeros are written to the MMI file.
The memory module function file programming screen is shown below:
The parameters and their valid ranges are shown in the table below.
