Common Parameter Area Section 4-2
Settings 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)
Explanation 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 fol-
lowing words will be allocated consecutively to common parameters and axis
parameters.
NC1 @ 3: m+32 to m+55
NC2 @ 3: m+60 to m+99
NC4 @ 3: 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 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).
