Transmission Bytes, Communication Cycle, Number of Retries to Slaves, Number of Slaves

Transmission bytes, communication cycle, number of retries to slaves, and number of slaves at execution of self-con-
figuration will be automatically set according to conditions including communication type, station type (Master or
Slave), and the largest slave station number (the largest number among the detected slave station numbers).

Number of
Retry to Slaves

Displays the maximum number of slave stations to which
the Master can retry transmission in one transmission
cycle when the Master has not received a normal
response from a slave.

Only for Master station. Set a number between
0 and 7. Cannot set for Slaves.

Number of Slaves

Displays the number of slave stations that can be con-
nected.
The number of slave stations that can be connected is
determined by communication type, communication
cycle, SigmaWin+ use/not use, and number of retry to
slaves.

Cannot be set.
