CAUTION
1 Replacing the memory module results in the loss of stored
data such as programs, parameters, and ladder. Before
attempting to replace the memory module, therefore, make
a backup copy of the stored data.
2 Make sure that the latches at both ends of the socket are
correctly engaged with the module. If either latch is not
engaged securely, it will not be possible to establish a
satisfactory electrical contact, possibly leading to a
malfunction of the NC unit.
