Common Parameter Area Section 4-3
m+1 will be allocated. Specify the bank number in the bank designation set-
ting (word m, bits 08 to 15).
Bank Designation (Word m, Bits 08 to 15)
If user-specified EM Area words (0E) are designated as the location for the
operating data area using the area designation setting (word m, bits 00 to 07),
use this setting to designate a bank number. The following bank numbers can
be designated: 0 (00) to 9 (09), A (0A), B (0B), C (0C). Do not, however, select
a bank that is being used as PLC file memory. If the DM Area words allocated
to Special I/O Units (00) or user-specified DM Area words (0D) are desig-
nated as the location of the operating memory area, set the bank designation
to 0 (00). Any other setting will result in an operating data area specification
error (error code 0010).
Note Do not set a bank number for a bank that is being used as PLC file memory. If
a bank that is being used as PLC file memory is set, the operating data area
settings will not be reflected in PCU operation and this will result in malfunc-
tion. When there are several PCUs mounted to the same PLC, be sure to set
the operating data areas for the PCUs so that they do not overlap with each
other. The PCU will not detect an error if operating data areas overlap, and
this may result in malfunction.
For details on the EM Area banks and how to use them as PLC file memory,
refer to the
SYSMAC CS/CJ Series Programmable Controllers Programming
Manual (W394).
Beginning Word of Operating Data Area (Word m+1)
If user-specified DM Area words (0D) or user-specified EM Area words (0E)
are designated as the location for the operating data area using the area des-
ignation setting (word m, bits 00 to 07), use this setting to designate the
beginning word of the operating data area. The beginning word is set in hexa-
decimal. The following settings are possible (varies with the model):
NC1 @ 3: 0000 to 7FE8 Hex (0 to 32744)
NC2 @ 3: 0000 to 7FD8 Hex (0 to 32728)
NC4
@
3: 0000 to 7FB8 Hex (0 to 32696)
If DM Area words allocated to Special I/O Units (00) are designated as the
location for the operating data area, this setting will not be used.
Example 1
The area in the CPU Unit’s DM Area beginning with word 1F40 Hex (8000) is
designated as the operating data area. The following words are allocated (var-
ies with the model):
NC1
@
3:D8000 to D8023
NC2 @ 3:D8000 to D8039
NC4
@
3:D8000 to D8071
Example 2
The area in bank 2 of the CPU Unit’s EM Area beginning with word 3A98 Hex
(15000) is designated as the operating data area. The following words are
allocated (varies with the model):
