Description
Data
―
[Ai1] Terminal analog
input
The analog input to [Ai1] terminal is captured to
the general-purpose analog input XA(0).
Parameter setting is not required. The input
characteristic follows the start/end function
([A011] to [A015]). When the parameter is the
initial value, 0 to 10VDC will be 0 to 10000.
0 to 10000
―
[Ai2] Terminal analog
input
The analog input to [Ai2] terminal is loaded to
the general-purpose analog input XA(1).
Parameter setting is not required. The input
characteristic follows the start/end function
([A101] to [A105]). If the parameter is the initial
value, 4 to 20 mA will be 0 to 10000.

Input terminal function
selection
General-purpose input 1 to 7 ([MI1] to [MI7]):
When [MI1] to [MI7] is assigned to an input
terminal, each terminal status is input to the
internal variables X(00) to X(06) (or Xw).

[C022]
[C026]
Output terminal
function
General-purpose output 1 to 3 ([MO1] to [MO3]):
When [MO1] to [MO3] is assigned to an
output terminal, the status of the internal
variables Y(00) to Y(02) (or Yw) is output to
the respective terminals.
44 to 46
