Operating Memory Area - Omron CS1W-NC113 Manual

Common Parameter Area
Settings
Explanation
The following settings are available.
Word m: 0000, 000D, 0X0E (X = 0 to 9, A, B, or C)
Word m+1: 0000 to 7FXX Hex (settings possible for "XX" will depend on the
model)
The meanings of each of the settings are given below.
Area Designation (Word m, Bits 00 to 07)
Designate the area in CPU Unit memory to be used for setting operating data.
The following settings are available.
00: DM Area Words Allocated to Special I/O Units
Memory from the area allocated to Special I/O Units in the CPU Unit's DM Area
will be allocated according to the unit number set for the PCU. The following
words will be allocated consecutively to common parameters and axis parame-
ters.
NC1j3: m+32 to m+55
NC2j3: m+60 to m+99
NC4j3: m+116 to m+187
0D: User-specified DM Area Words
Words within the DM Area starting from the beginning word specified in word
m+1 will be allocated.
0E: User-specified EM Area Words
Words within the EM Area starting from the beginning word specified in word
m+1 will be allocated. Specify the bank number in the bank designation setting
(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 oper-
ating 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 PC file memory. If the DM Area words allocated to
Special I/O Units (00) or user-specified DM Area words (0D) are designated 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 PC file memory. If a
bank that is being used as PC file memory is set, the operating data area settings
will not be reflected in PCU operation and this will result in malfunction. When
there are several PCUs mounted to the same PC, 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 mal-
function.
For details on the EM Area banks and how to use them as PC file memory, refer
to the SYSMAC CS1 Series Programmable Controllers Operation Manual
(W339).
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 designa-
tion 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 hexadecimal. The
following settings are possible (varies with the model):
NC1j3: 0000 to 7FE8 Hex (0 to 32744)
NC2j3: 0000 to 7FD8 Hex (0 to 32728)
NC4j3: 0000 to 7FB8 Hex (0 to 32696)
If DM Area words allocated to Special I/O Units (00) are designated as the loca-
tion for the operating data area, this setting will not be used.
