Setting Item Details
Master/Slave Sets whether the Machine Controller is used as a Master station or a
Slave station.
Own Station Address When the Machine Controller is being used as a master station, the
local station address is fixed at 0 and cannot be changed. When it is
being used as a slave station, set a station address between 1 and 30.
Message Trust Level Sets the error recovery level for sending MEMOBUS commands.
0 Send command just once and wait indefinitely for a response
from the destination.
1 Send command once and resend if a response is not received
within 8 seconds.
2 When sending the command, send each word of data twice
consecutively and wait indefinitely for a response from the
destination. This method improves transmission quality but
reduces transmission efficiency by 50%.
