How you use the 6DYHSURMHFWWRPHPRU\FDUG / 5HWULHYHSURMHFWIURPPHPRU\
FDUG functions depends on the location of the SIMATIC micro memory card:
• If the micro memory card is inserted in the MMC slot, select a project level that
is uniquely assigned to the CPU from the SIMATIC Manager project window
(e.g. CPU, program, source or blocks). Select the 7DUJHWV\VWHP!6DYH
SURMHFWWRPHPRU\FDUG or 7DUJHWV\VWHP!5HWULHYHSURMHFWIURPPHPRU\
FDUG menu command. All project data is written to the MMC, or retrieved from
the card.
• If project data is not available on the currently used programming device
(PG/PC), you can select the source CPU via "Available nodes" window. Select
menu command 3/&!6KRZDYDLODEOHQRGHV to open the "Available nodes"
window. Select the connection/CPU that contains your project data on Micro
Memory Card. Now select the menu item 5HWULHYHSURMHFWIURP0HPRU\&DUG.
• If the Micro Memory Card is in the MMC programming slot of a PG or PC, you
can open the "S7-Memory Card window" via the menu command
)LOH!60HPRU\&DUG!2SHQ. Select the 7DUJHWV\VWHP!6DYHSURMHFWWR
PHPRU\FDUG or 7DUJHWV\VWHP!5HWULHYHSURMHFWIURPPHPRU\FDUG menu
command. to open a dialog in which you can select the source or target project.

Project data may generate a high volume of data. Especially in RUN mode and
during read/write access to the CPU, this can lead to waiting periods of several
minutes.

Once you have more than one member of service and maintenance staff occupied
with a maintenance or service task on a SIMATIC PLC, it may be difficult to make
current project data quickly available to each staff member.
However, if these staff members have access to project data that is available
locally on a serviced CPU, they can make their changes and quickly release the
updated version to other staff members.
