8.1.2.8 Assigning I/O Addresses
The AS Series does not support manually assigned addresses. Addresses are automatically assigned to an
input/output module through HWCONFIG in ISPSoft. You assign a start address to the first remote module installed
on the right side of the I/O module slot (SCM module). The following I/O module is automatically assigned with the
next address. For remote module configuration, refer to Section 8.1.2.9 for more details.
The following table shows the addresses (devices) that are automatically assigned to an input/output module through
HWCONFIG in ISPSoft. Refer to the following table to see the actual allowable range for program design, while
editing a PLC program. Below, local indicates the IO module is connected on the right side of the CPU and Remote
indicates the IO module is connected on the right side of remote module.

Digital module
(DIO)
Input points:
X1.0 ~ X63.15
Output points:
Y1.0 ~ Y63.15
Local: D28000 ~ D28999
Remote: D29000 ~ D29999

Each module takes 20 devices.
Data device number will not be
shown; it is only for PLC internal use.
Maximum points in total: 1024 points.
For modules with less than 16 points,
they will be counted as 16 points.

Local: D28000 ~ D28999
PU module takes 40 devices.
HC module takes 20 devices.
Up to 8 PIO modules are configurable
locally, but not available remotely.
Network
module (NIO)
N/A
Local: D28000 ~ D28999
Remote: D29000 ~ D29999
#1
Each module takes 20 devices.
Up to 4 NIO modules are
configurable locally. SCM module can
be used as remote module but not on
the right-side of the remote module.
DNET modules can only be
connected locally.
SIL modules can either be used
locally or remotely.
Communication data area:
D26000 ~ D27599
Each module takes 400 devices.
Note: #1: the remote module itself also takes 20 devices.
