Number Of Transmission Points Setting - Mitsubishi Electric FX3U-128ASL-M User Manual

• When the main unit is FX
M is connected to the far ([2]) side
If the number of I/O occupied points on the main unit side is 112 points (including 8 input/output points
occupied by the FX
the FX -128ASL-M is 80 points,

128 - 80 = 48 points

Remote I/O corresponding to 48 points can be assigned in the FX
(Actually, 32 points for 1 station can be assigned).

Number of transmission points setting

The 128ASL-M requests the main unit for the number of transmission points (number of I/O occupied points)
for the AnyWireASLINK system through the rotary switches.
The correspondence between the rotary switch setting value and the number of input/output points is as
follows:

The 128ASL-M requests the main unit for the number of input points and number of output points set by the
rotary switches.
The following restriction is imposed on the number of transmission points actually assigned by the main unit:
• Number of input points + Number of output points ≤ 128 points
• In the case of "Number of input points + Number of output points ≥ 128 points", the number of input points
is assigned first, and then the number of output points is assigned to remaining available points.
Example: When the input rotary switch is set to "9" and the output rotary switch is set to "7"
Number of input points "96" + Number of output points "64" = 160 points ≥ 128 points
As a result, 96 input points and 32 (= 128 - 96) output points are assigned.
• When the number of transmission points assigned by the main unit is less than 128 points and "Input rotary
switch setting value + Output rotary switch setting value" exceeds that, the number of input points is
assigned first, and then the number of output points is assigned to remaining available points.
Example: When the input rotary switch is set to "7", the output rotary switch is set to "7", and only 48
points are assigned by the main unit
Number of input points "64" + Number of output points "64" = 128 points ≥ 48 points
As a result, 48 input points and 0 output point are assigned.
Caution
Even if the slave module is connected and set to the area (address) beyond the number of input points set by
the rotary switch, input signals from the slave module are not reflected in the buffer memory.
In the same way, even if values are written to the buffer memory area (address) beyond the number of output
points set by the rotary switch, they are not output as actual signals.
