Transmission cycle time
The transmission cycle time is the time required for the 128ASL-M and all the slave modules to update I/O
data.
The transmission cycle time of the 128ASL-M is listed in the table below.
However, "Number of input point settings" and "Number of output point settings" shown in the table below
indicate the number of input points and number of output points assigned to 128ASL-M by the main unit (, so
not set by the rotary switches of the 128ASL-M).

Condition, remarks
When the larger one between the number of assigned
input points and the number of assigned output points
meets the following expression, the transmission cycle
time becomes the value shown on the left:
Number of input or output points ≤ 32
When the larger one between the number of assigned
input points and the number of assigned output points
meets the following expression, the transmission cycle
time becomes the value shown on the left:
32 < Number of input or output points ≤ 64
