12.3.1 Communication function
(1) Parameter settings
Set the execution conditions for the transient transmission with the parameters
listed below.
In the default settings, both the number of transients that one network can
execute in one link scan ("Maximum no. of transients in 1 scan") and the number
of transients that one station can execute in one link scan ("Maximum no. of
transients in one station") are set to 2 times. Change the number of transients
that can be executed in a link scan as necessary (Refer to Points below).

Transient setting
POINT
(1) By increasing the number of transients, multiple transient instructions can be
executed at the same time (in one link scan).
(2) If the number of transients is increased and the transient request was issued in
each station at the same time, the link scan time becomes temporarily longer
and the cyclic transmission is also affected. Do no set unnecessarily large
values.
(3) When the transient transmission and the low-speed cyclic transmission are
used at the same time, these transient setting parameters limit the total number
of transient and low-speed cyclic transmissions.
