This setting specifies whether the operating data area is to be set in the DM area
or the EM area.
X = D (DM area)
E (EM area)
If anything other than the above is set, or if the beginning word designation (in
m+1) is out of the permissible range, an operating data area word error will be
generated. If such an error is generated, the following conditions will result. In
that case, correct the setting and either power up again or restart the PCU.
•
The RUN indicator on the PCU’s front panel will light, and the ERR indicator will
flash.
•
The X-axis Error Flag will turn ON.
Operations (such as monitoring and data transfers) from the SYSMAC-NCT
Support Tool, however, can be executed as usual.

This setting specifies the beginning word for the operating data area. The words
that can be specified are the read/write-enabled DM and EM (bank 0 only) words
shown in the following table.
PC model Areas that can be set
C200H DM 0000 to DM 0899
C200HS
C200HE(-ZE) DM 0000 to DM 0999
DM 2000 to DM 5999 (See note.)
C200HX/HG(-ZE) [For Unit No. 10]
DM 0000 to DM 0999
DM 2000 to DM 5999 (See note.)
EM 0000 to EM 6143 (bank 0 only)
[For Unit No. 16]
DM 0000 to DM 0999 (See note.)
DM 2600 to DM 5999
EM 0000 to EM 6143 (bank 0 only)
Note The upper limit varies depending on the memory capacity.

Mounting position

Parameter designation
08 07
The “mounting position” setting specifies whether the PCU is mounted to a
Remote I/O Slave or to the CPU Rack or Expansion I/O Rack.
00: PCU mounted to CPU Rack or Expansion I/O Rack
01: PCU mounted to Remote I/O Slave
Note If this setting is “00” but the PCU is actually mounted to a Slave, a Special I/O Unit
error will be generated. If that occurs, correct the setting to “01” and then power
the PCU up again or restart it. Likewise, if the PCU is mounted to the CPU Rack
or an Expansion I/O Rack, be sure to set this “mounting position” setting to “00.”
If it is set to “01” in that case, the responses to instructions from the Program-
mable Controller will be one or two scans slower than if it is set to “00.”
