FP0R User's Manual
Set SYS1 to change the waiting time for a link to be added to the PLC link
from the default value of 400ms to 100ms.
LD Body
If there are any stations that have not been added to the link,

the setting should not be changed as long as a longer link
transmission cycle time does not cause any problems.
The SYS1 instruction should be executed at the beginning of the

program, at the rise of R9014. The same waiting time should be
set for all linked PLCs.
The waiting time should be set to a value of at least twice the

maximum scan time for any of the PLCs connected to the link.
If a short waiting time has been set, there may be PLCs that

cannot be added to the link even if their power supply is on. (The
shortest time that can be set is 10ms.)
If the power supply of any given PLC fails or is turned off, it takes (as a
default value) 6.4 seconds for the transmission assurance flag of that PLC
to be turned off at the other stations. This time period can be shortened
using the SYS1 instruction.
Set SYS1 to change the time that the PLC link transmission assurance is
off from the default value of 6.4s to 100ms.
