♦
The NS-series PT may operate incorrectly if addresses that are reserved by the system are ac-
cessed. Do not access these addresses.
System memory is allocated to PLC areas as shown below.
Set the allocation addresses for the system memory on the Initial Tab Page of the CX-Designer. Select
PT – System Settings
to access the Initial Tab Page.

♦
The method for allocating system memory in the PLC areas is the same as for the NT Series. Refer
to
2-4-3 System Memory Compatibility with the NT Series
for details.
♦
Set a BOOL variable with 64 elements when allocating a tag.
RUN Signal (Pulse) ($SB0)
$SB0 notifies the host memory and PT memory that the PT is operating (normal operation on normal
screens.) During operation, $SB0 alternates between ON and OFF according to the interval set for
RUN signals (pulses).
