8. Programming
After performing address setup for a slave, and registering the address to the LPS (List
of Projected Slaves), the contact input/outputs of the slave then become addressable by
a user program.
8.1 Programming
ASi Statuses
You may check the following ASi statuses from a user program.

" □□□ " in a relay number denotes the slot number where the ASi Master module is installed.
In general, you should always check that both NORMAL_OPERATION and
CONFIG_OK are on during module operation.
(Note that even if CONFIG_OK turns off, NORMAL_OPERATION may not turn off).
As a minimal prerequisite, you should not start operation until NORMAL_OPERATION
turns on. The other statuses should also be in appropriate states depending on the
required operating conditions.
TIP
Although the ASi Master module supports both BASIC programs and ladder programs, ladder
programs are more commonly used. Hence, subsequent descriptions and explanations will be based
on ladder programs.
When writing BASIC programs, use the data position numbers given in this manual.
