This parameter is valid only when I/O
parameter No. 18 is set to “1.”
(Example) If the set value (bits 4 to 11)
is “05

,” the timer period
becomes 10 ms x 5 = 50 ms.
If the set value is “0

system error will occur
immediately upon occurrence
of a network link error.

Bit 16 to 27:
Value of Link Timeout at initializing of the
Fieldbus (100msec)
(ASEL/PSEL: Main application of Ver.0.36 or later
SSEL: Main application of Ver.0.42 or later)
(Example)
The initial value C80000H is bit 16 to 27
= C8H = 200 (in 100ms unit)
200 × 100ms = 20sec
It waits for communication to be established
for 20sec at the maximum from the startup.
