FUNCTIONS

■OUTPUT HOLD or OUTPUT OFF

In normal conditions, the module outputs the signal from

the preferred bus A.

When an error is detected, the output is switched to the

data from the bus B.

•Output Hold

If both are in error, the module holds the signal and stands

by until one of the communications recovers.

•Output OFF

If both are in error, the module outputs OFF signals and

stands by until one of the communications recovers.

At the startup, it outputs OFF until the communication is

established and normal data is received.

■ MAX. ON POINTS AT ONCE

Function available for One-Shot Output Mode and ON/OFF

Control Output Mode.

Divide the points to be ON at once. When the total of load

current exceeds the maximum load current, "Max. ON

Points at Once" function is activated.

The number of the channel turned ON is output in order

from the lowest.

Example: Max. ON Points at Once: 1 point; One-shot ON

Time setting: 1 sec.

Ch1, 2, 4, 8 all ON: Ch1→Ch2→Ch4→Ch8 are turned ON in

this order in a total time of 4 seconds.

Note: When writing in the same channel two or more times,

check the previous output completion status to set the

output.
