Counter Area 4,096: C0000 to C4095 (used for counters only)
DM Area 32 Kwords: D00000 to D32767
Used as a general-purpose data area for reading and writing data in
word units (16 bits). Words in the DM Area maintain their status when
the NSJ Controller is turned OFF or the operating mode is changed.
Internal Special I/O Unit DM Area: D20000 to D29599 (100 words ×
96 Units)
Used to set parameters for Special I/O Units.
CPU Bus Unit DM Area: D30000 to D31599 (100 words × 16 Units)
Used to set parameters for CPU Bus Units.
EM Area NSJ@-@@@@-G5D
32 Kwords per bank, 3 banks max.: E0_00000 to E2_32767 max.
Used as a general-purpose data area for reading and writing data in
word units (16 bits). Words in the EM Area maintain their status when
the NSJ Controller is turned OFF or the operating mode is changed.
The EM Area is divided into banks, and the addresses can be set by
either of the following methods.
Changing the current bank using the EMBC(281) instruction and set-
ting addresses for the current bank.
Setting bank numbers and addresses directly.
EM data can be stored in files by specifying the number of the first
bank.
NSJ@-@@@@-M3D
Not supported.
Index Registers IR0 to IR15
Store actual memory addresses for indirect addressing. Index regis-
ters can be used independently in each task. One register is 32 bits (2
words).
Task Flag Area 32 (TK0000 to TK0031)
Task Flags are read-only flags that are ON when the corresponding
cyclic task is executable and OFF when the corresponding task is not
executable or in standby status.
Trace Memory 4,000 words (trace data: 31 bits, 6 words)
File Memory Memory Cards: OMRON Memory Cards can be used (MS-DOS for-
mat).
EM file memory: Part of the EM Area can be converted to file memory
(MS-DOS format).
The NSJ@-@@@@-M3D does not support the use of EM file memory.
