Appendix 10.2 Send timing

The low-speed cyclic transmission is executed separately from the normal cyclic

transmission.

Number of stations to be sent in 1 link scan varies depending on the parameter settings.

When setting the [Transmit data of one station in 1 link scan], one station can transmit

data once in 1 link scan for each link cycle of the low-speed cyclic.

When setting the [Fixed term cycle interval setting] and [System times], the number of

stations set in the [Maximum No. of transients in 1 scan] of [Transient setting] can

transmit data once in 1 link scan for each link cycle of the low-speed cyclic.

For example, when setting the [Maximum no. of transients in 1 scan = 2 Times], two

stations can transmit data once in 1 link scan for each link cycle of the low-speed cyclic.

The following figure shows the send timing example when four stations execute the

low-speed cyclic transmission simultaneously after setting the [Transmit data of one

station in 1 link scan] with a parameter.
