Accessing AS ‐ Interface Objects for AS ‐ Interface Master Module 1
The I/O data and parameters of slaves on the AS ‐ Interface bus, the status of the AS ‐ Interface bus, and various list infor ‐
mation of the slaves are allocated to the AS ‐ Interface master module EEPROM. This information is called AS ‐ Interface
objects, which can be accessed through the AS ‐ Interface devices, such as internal relays M1300 through M1997 and data
registers D1700 through D1999. The allocation for AS ‐ Interface master module 1 is shown in the table below.
*1: The time required for the CPU module to update the device data. When using AS ‐ Interface master module 1, the scan time
increases by a minimum of 10 ms. For AS ‐ Interface master module 2, see page 24 ‐ 32.
*2: These AS ‐ Interface device data can be read or written using WindLDR. For details, see page 24 ‐ 34.
*3: The LPS, PCD, and PP are set and downloaded to the CPU module using WindLDR. For details, see page 24 ‐ 36.
*4: The analog I/O data is updated only when an analog slave is connected to the AS ‐ Interface bus.
Accessing AS ‐ Interface Objects for AS ‐ Interface Master Module 2
When using two AS ‐ Interface master modules, the AS ‐ Interface objects for the second AS ‐ Interface master module can
be assigned to any internal relays and data registers and accessed using RUNA or STPA instructions. See page 24 ‐ 32.
