・
For Polling, master has I/O information of all slaves, therefore, if you often use I/O communication
than data communication, please select this system. But, it takes time to check the state of all
slaves if there are a lot of slaves. Master automatically communicates to all slaves including
repeaters.
・
For polling, it outputs communication error when wireless communication is cut off.
(Communication error is output after about 3 times of polling time. But it is less than 30 sec., it
outputs after 30 sec.)
・
Data communication is impossible with “[I/O] 1:N topology for report”, therefore setting of timeout
period is not available.
Reference
：
For timeout period of Master <9.2 Reference>
(RS485 type)
(I/O type)
Normally, option is not necessary. In below cases, change it.
・
When communication between terminals is executed with start character “>”
(With setting as this, it might cause malfunctions.)
・
When 10-characters delimiter time of communication between terminals (time from complete
communication to start next communication) is too short. (Example: When using "KW4M
Eco-Power Meter", set it 50-characters.)
・
Timeout period is too short.
When it is set to “0”, master calculates to decide timeout period automatically. When radio wave
environment is bad such as repeating retry because repeaters and data amount is big, extending
timeout period makes communication possible.
Input and master is displayed in the routing table view.
Initial asterisk (

No. 0. (After completing transfer to master and transfer from master,
