I/O Assignment Tab Page
This tab page is used to set the I/O devices connected in the MECHATROLINK and their
transmission definition data.
Own Station Address The MP930 is always a Master station, so the local station address is
fixed at 0 and cannot be changed.
Message Trust Level Sets the error control method used when sending MEMOBUS com-
mands. In the MP930, the Message Trust Level is fixed at 1.
0 Send command just once and wait indefinitely for a response
from the destination.
1 Send command just 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%.
Trans Cycle The transmission cycle can be set to 2 ms only.
Transmission Speed: The transmission speed can be set to 4 Mbps
only.

ule Configuration Definition Window.
