EUCHNER MSC - 5.3.2. USB connection; 5.3.3. MSC configuration memory (M-A1)

English
RESTORE function
If the module MSC-CB is faulty, it can be replaced with a new module. As the entire config-
uration is saved on the M-A1 memory card, it is only necessary to insert this card in the
new module and switch on the MSC system, the backed up configuration will then be
loaded immediately. In this way interruptions in operation can be reduced to a minimum.

The LOAD and RESTORE functions can be deactivated using the software (see Figure 32).

The expansion modules must be assigned addresses during installation so they can
be used (see NODE_SEL).
 Each time M-A1 is used, it is to be carefully checked whether the configuration selected
is the configuration prepared for this specific system. Undertake a complete function
check on the system comprising the MSC and all devices connected to it (see
CHECKING the system).
