blocks can be held during power interruptions with a battery. If there is a bat-
tery error, the contents of these areas may not be accurate after a power
interruption. If the contents of the DM, EM, HR Areas, and the variables set to

to a PLC to which is mounted a non-insulated Unit (CS1W-CLK13/53/12/52(-
V1) or CS1W-ETN01) connected to an external power supply. A short-circuit
will be created if the 24 V side of the external power supply is grounded and
the 0 V side of the peripheral device is grounded. When connecting a periph-
eral device to this type of PLC, either ground the 0 V side of the external
power supply or do not ground the external power supply at all.
