CPU Overview
CS1D Duplex CPU Specifications
Common Specifications other than Duplex Specifications (continued)
Data Memory (DM) Area
Extended Data Memory
(EM) Area
Index Registers
Data Registers
32K words: 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 PLC is turned OFF or the operating mode is changed.
Special I/O Module DM Area: D20000 to D29599 (100 words x 96 Units)
Used to set parameters for Special I/O Modules.
CPU Bus Unit DM Area: D30000 to D31599 (100 words x 16 Units)
Used to set parameters for CPU Bus Units.
Inner Board DM Area: D32000 to D32099
Used to set parameters for Inner Boards.
32K words per bank, 13 banks max.: E0_00000 to EC_32767 max. (Not available on some CPUs.)
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 PLC 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 setting 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.
IR0 to IR15
Store PLC memory addresses for indirect addressing. One register is 32 bits (2 words).Index registers
can be set to be shared by all tasks or to be used independently by each task.
DR0 to DR15
Used to offset the PLC memory addresses in Index Registers when addressing words indirectly.
Data registers can be set to be shared by all tasks or to be used independently by each task
Task Flags
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: Compact flash memory cards can be used (MS--DOS format).
EM file memory: The EM Area can be converted to file memory (MS--DOS format)
