CJ1G, CJ1G/H-H, and CJ1M PLCs support only 1:N NT Link communications.
Note 1. AR00000 to AR01471 and AR10000 to AR11535 can be read or written in CJ2 PLCs. For other PLCs,
AR00000 to AR00959 can be read or written and AR00000 to AR00447 and AR10000 to AR11535 are
read only.
2. CJ1G, CJ1G-H, CJ1H, CJ1H-H, and CJ1M PLCs do not have an LR area, but if the screen data uses the
LR area, this will be automatically converted internally to CIO 01000 to CIO 01199 in the CIO area.
3. Task flags cannot be used with PTs.
4. These areas cannot be set as the allocated addresses for system memory $SB or $SW.
Communications cannot be performed simultaneously for 63 or more points. If 64 or more points are set,
a communications (settings) error will occur during operation. These areas cannot be used by
READCMEM or WRITECMEM macros.
These areas cannot be set to ON/OFF Buttons or other objects that write bit data. These areas can be
set only to bit lamps and other objects that read bit data.
5. CJ1M PLCs do not have an EM area.
6. Specify a bank for the data area when setting a bit address in the EM. If the data area is specified using
the current bank, the ON/OFF function may not be able to be used correctly, depending on the status of
other bits in the EM area for the same word number.
