Modular Safety Control System MSC

5.3.3.2. RESTORE function
If the module MSC-CB is faulty, it can be replaced with a new module. As the entire configuration 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.
Important!
Ì The LOAD and RESTORE functions can be deactivated using the software (see Figure 44: EUCH-
NER Safety Designer, selecting extension module on page 68).
Ì The extension modules must be assigned addresses during installation so they can be used (see
NODE_SEL).
WARNING
Ì Each time M-A1 is used, it is to be carefully checked whether the configuration selected is the con-
figuration prepared for this specific system. Undertake a complete function check on the system
comprising the MSC and all devices connected to it (see section "CHECKING the system" Page
80).
