1: Data separation prevention is when older data with the meaning of 2-word (32 bit) link data such as the
positioning unit's current position are prevented from being separated into new data with 1-word (16 bit)
units due to cyclic transmission timing.

(4) Supplementary setting screen
Selects the channel (MELSECNET/H board) performing the settings.
Sets a constant link scan. (Setting range: 1 to 500 ms) If it is not run, do not
input anything.
Sets the number of stations with transmission errors that can undergo
return to system in 1 link scan.
Set when running the multiplex transmission function.
Set when executing the control station move function.
Set when preventing data separation of link data in station units in cyclic
transmissions.
Sets the number of transients that can be executed in one link scan by one
network (total for 1 network as a whole).
(Valid setting: 1 to 255 times; Default: 2 times)
Sets the number of transients that can be executed in one link scan by one
station.
(Valid setting: 1 to 10 times; Default: 2 times)
Set in cases such as when data to be transmitted to another station are
collected and sent one station at a time in 1 link scan.
Carries out low speed cyclic transmission at the preset intervals.
(Valid setting interval: 1 to 65535 s.)
Carries out low speed cyclic transmission in accordance with the preset
time. (Settings: Year, Month, Day, Hour, Minute, Second)
