[DESIGN PRECAUTIONS]
!
DANGER
• If a communication error occurs in the AS-i system, the input will turn OFF from the slave having
the communication error.
Output to the slave having the communication error will be held or cleared depending on the
slave specifications.
The AS-i system communication error can be confirmed with the buffer memory's List of Active
Slaves (LAS) (15H to 18H) and with the input signal Configuration error (X4).
Using the above information, configure an interlock circuit on the sequence program so that the
system activates safely.
There is a risk of accidents caused by incorrect outputs or operations.
• Depending on the module fault, the input/output could enter ON or OFF status.
Provide an external monitoring circuit for I/O signals that could lead to major accidents.

!
CAUTION
• Do not bundle AS-i cable together with main circuit or power lines, or lay them close to these
lines.
As a guide, separate these lines by a distance of at least 100 mm, otherwise malfunctions may
occur due to noise.
