Notes for Using Expansion I/O Modules of Version 7 or earlier
When using 3 or more expansion I/O modules including
those of the versions listed below, immediately after power-
up, it takes a specific period of time for the base module to
accept input signals from the expansion I/O modules. Until
the output terminals on the expansion I/O module are actu-
ally turned on or off.
Expansion I/O Modules
FL1B-M08C2R2(Version 1 to 7), 
FL1B-M08B1S2(Version 1 to 7), 
FL1B-M08B2R2(Version 1 to 7), 
FL1B-M08D2R2(Version 1 to 7), 
FL1B-J2B2(Version 1 to 7), 
FL1D-K2B2(Version 1)
For identifying the version, see page 5.

Version 8 or later
*1 Output signal of base module and expansion modules
are reflected 1 scan time after each input signal has been re-
flected.
*2 During the initialization period of expansion I/O modules,
inputs and outputs are off. In addition, the length of initializa-
tion period varies with expansion I/O modules , and I/O re-
sponse depends on the expansion I/O modules.
