Precautions
■Reflection of the settings
The initial settings registered using an engineering tool are reflected to a remote device station by writing the settings to a
CPU module and turning on 'Remote device station initialization procedure registration instruction' (SB000D).
■Processing time
Because one step is executed per link scan, more setting items extend the processing time further than that of when a
program is used.
■While 'Remote device station initialization procedure registration instruction' (SB000D) is on
Data in the remote I/O (RX, RY) and remote register (RWr, RWw) stops being refreshed.
■Handling of signals that are required to be always on (such as CH. Conversion enable flag
of an AJ65BT-64RD3/4)
Turning off 'Remote device station initialization procedure registration instruction' (SB000D) after the initial processing is
completed turns off all the RY signals that have turned on while the initial procedure registration is performed. To prevent this,
use a program to turn on signals that are required to be always on.
■Turning on 'Completion status of remote device station initialization procedure' (SB005F)
When 'Specification of remote device station to be initialized' (SW0014 to SW0017) is selected, 'Completion status of remote
device station initialization procedure' (SB005F) does not turn on until the procedure registration is normally completed in all
the stations. If a faulty station exists, turn off 'Remote device station initialization procedure registration instruction' (SB000D)
depending on the completion status of other stations.
■Initialization procedure registration for a standby master station
The initial setting cannot be configured in a standby master station. When replacing a remote device station while a standby
master station is operating as a master station, configure the initial setting on a program.
■When the instruction is not required
The initialization procedure registration instruction may not be required under some situations, such as when the remote input
(RX) is set as a condition device.
