(3) Validating the remote device station initial settings

This section explains the link special relays (SB) relating to the initial settings of
remote device stations.
Numeric values in parentheses in the Number column indicate addresses and bit
positions of the buffer memory.
Example: For buffer memory address 5E0
Starts initial processing using the information registered during
the initialization procedure registration.
While SB000D is on, the refresh of the remote input/output and
remote registers stops.
OFF: No instruction
ON: Instructed
Indicates the execution status of the initialization procedure.
OFF: Not executed
ON: Being executed
Indicates completion status of the execution of the initialization
procedure execution.
OFF: Not complete
ON: Complete
Stores the execution result of initialization procedure registration
instruction with SB000B.
0: Normal
Other than 0: Store the error code (see Section 13.3).
For details on how to create a program, see Section 10.2.4.
POINT
(1) When remote device station initialization procedure registration instruction
(SB0000) is turned off after the initial processing completion, all of the RY
signals that has been turned on in the initial procedure registration is turned off.
Therefore, about signals that are required to turn always on, such as conversion
valid signal, they should be turned on in the sequence program.
(2) If the procedure registration is not completed for all stations registered to the
remote device station initialization procedure registration, the completion status
of remote device station initialization procedure (SB005F) does not turn on.
If there is a faulty station, turn off the remote device station initialization
procedure registration instruction (SB000D) according to the completion status
of the other stations.
