Slave Address Shading Colors
Operating status of the slave can be confirmed by viewing the shading color at the slave address on the Configure AS-
Interface Master dialog box. The screen display can be updated by clicking the Refresh button.
Change Slave Address
When a slave is connected to the AS-Interface master module, the slave address can be changed using
WindLDR
.
To change a slave address, from the
WindLDR
menu bar, select Configure
> AS-Interface Master. The Configure AS-Interface Master dialog box
appears.
Click a slave address to open the Change Slave Address dialog box. Select
Slave A or Slave B, enter a required address in the New Address field, and
click OK. The Change Slave Address dialog box is closed. The new slave
address is stored in the slave module nonvolatile memory.
Changing slave addresses takes approximately 40 seconds.
If the command is not processed correctly, the error message “AS-Interface Master Error” and an error code will appear.
See page 7-5.
The address cannot be changed in the following cases.

Error Code
Description
1
•
An error was found on the expansion I/O bus.
7
•
The AS-Inter face master module is in local mode.
8
•
The slave you are tr ying to change does not exist.
•
A slave of the designated new address already exists.
•
While a standard slave was set at A address, attempt was made to set an A/B slave at B
address of the same number.
•
While an A/B slave was set at B address, attempt was made to set a standard slave at A
address of the same number.
• Duplicate slave addresses
Each slave must have a unique address. Do not connect two or more slaves with the same address,
otherwise the AS-Interface master module cannot locate the slave correctly. When two slaves have
the same address and different identification codes (ID, I/O, ID2, ID1), the AS-Interface master
module detects an error. When two slaves have the same address and same identification codes, the
AS-Interface master module cannot detect an error. Failure to observe this warning may cause
severe personal injury or heavy damage to property.
Warning
Caution
• When a slave with address 0 is connected to the AS-Interface master module, power up the
Micro-
Smar t
CPU module first. Approximately 5 seconds later, turn on the AS-Interface power supply.
If the CPU module and AS-Interface power supply are turned on at the same time, the AS-Inter-
face master module enters normal protected offline. In this mode, slave addresses can be changed,
but the slave status cannot be confirmed on
WindLDR
.
