Mitsubishi Electric MELSEC iQ-F FX5 User Manual page 50

When all bits are off, an initial processing is performed in all the stations set in "Initial Settings" under "Basic
Settings."
3.
Configure the initialization procedure registration by turning on 'Remote device station initialization procedure registration
instruction' (SB000D).
During the initial processing in the station number 3, other stations (station numbers 1, 5, and 7) continue the control.
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, SW0015) 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.
■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.
