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.
