Expansion modules numbering examples
It is a system made up of an axes board with 40I/24O and two expansion modules with 64I/32O
available in each one of them.
The inputs/outputs of the first module cannot be set by parameter; therefore, the inputs must
be numbered from I1 on and the outputs from O1 on.
Case 1: We wish to number inputs and outputs by setting parameters NUILOn and NUOLOn to zero.
First expansion module Second expansion module
NUILO1=0 NUILO2=0
NUOLO1=0 NUOLO2=0
The first expansion module assigned inputs I65 through I112 and outputs O33 through O64.
The second expansion module assigned inputs I129 through I192 and outputs O65 through O96.
The inputs of the first expansion module are numbered sequentially after the last input of the
first module (I64+1 = I65). The inputs of the second expansion module are numbered
sequentially after the last available input of the first expansion module (I128+1 = I129). Follow
the same procedure for the outputs.
Case 2: We wish the inputs and outputs to be sequential, but starting with I41/O25, so they are
numbered after the 40I/24O of the axis board.
First expansion module Second expansion module
NUILO1=41 NUILO2=0
NUOLO1=25 NUOLO2=0
The first expansion module assigned inputs I41 through I104 and outputs O25 through O56.
The second expansion module assigned inputs I105 through I168 and outputs O57 through O88.
The inputs of the first expansion module are numbered sequentially after the value assigned to
parameter NUILO1 (I41) chosen with the restriction (8n+1). The inputs of the second expansion
module are numbered sequentially after the last input used in the first expansion module (I104+1
= I105). Follow the same procedure for the outputs.
Case 3: We wish the inputs and outputs start at I65/O33 the first expansion module and at I201/O113
the second expansion module.
First expansion module Second expansion module
NUILO1=65 NUILO2=201
NUOLO1=33 NUOLO2=113
The first expansion module assigned inputs I65 through I112 and outputs O33 through O64.
The second expansion module assigned inputs I201through I264 and outputs O113 through
O144.
The inputs of the first expansion module are numbered sequentially after the value assigned to
parameter NUILO1 (I65) chosen at will with the restriction (8n+1). The inputs of the second
expansion module are numbered sequentially after the value assigned to parameter NUILO2
(I113) chosen at will with the restriction (8n+1). Follow the same procedure for the outputs.
