7.3.2 Send timing

7 - 11
The low-speed cyclic transmission is executed separately from the normal cyclic
transmission. This section describes the setting, processing interval and link cycle of
the low-speed cyclic transmission.
(1) Transmission setting
The link cycle of the low-speed cyclic transmission varies depending on its
transmission setting.
The setting can be made at "Specification of low speed cyclic transmission" on
"Supplementary setting". (Refer to Section 7.3.3.)
The following lists the setting options.
Setting item
Transmit data of one station
in 1 link scan
Fixed term cycle interval
setting
System times
1: Maximum no. of stations capable of sending data during 1 link scan of
normal cyclic transmission varies depending on the "Maximum no. of
transients in 1 scan" setting.
Refer to Section 7.4.1 for the "Maximum no. of transients in 1 scan" setting.
Description
Low-speed cyclic data of max. one station are sent during
one link scan of normal cyclic transmission.
Low-speed cyclic data are sent at a specified time
1
interval.
Low-speed cyclic data are sent at a specified time.
