The I/O Map group displays the current mapping for the I/O modules in
the system, and allows the user to manually assign the I/O mapping for
any of the I/O modules in the system.
Slot - this column displays
the slot number in which the module is detected
Mod ID - this column displays
the Module ID of the I/O module that is detected.
Note:
I/O modules that have the same I/O footprint will also have the same Module
ID regardless of the type of I/O, for example, all of the 8-point Discrete
input modules will have the same Module ID, regardless of whether they
have AC or DC inputs.
Slot I/O - this column displays
the number and type of I/O points that the detected I/O module consumes.
Modules that have multiple types of I/O will display each number and type
separated by a "/":
X - Discrete
Inputs - for example 16X = 16 Discrete Inputs
Y - Discrete
Outputs - for example 8Y = 8 Discrete Outputs
Note: 12pt. Discrete I/O modules
consume 16 points. The first 6 points are assigned, two are skipped, and
then the next 6 points are assigned. For example, a D2-12TA installed
in slot 0 would use Y0 to Y5, and Y8 toY13 for the actual inputs; Y6 to
Y7 and Y14 to Y15 would be unused.
Note: 4pt. Discrete I/O modules
consume 8 points. The first 4 points are assigned to the actual I/O points,
the next 4 are unused. For example, a D2-04TD1 installed in slot 0 would
use X0 to X3 for the actual inputs and X4 to X7 would be unused.
WX - Word (Analog)
Inputs (16-bit signed) - for example 4X / 4WX = 4 Discrete Inputs and
4 Word (Analog) Inputs
Note: the Discrete Inputs for
Analog Input modules are the 'broken transmitter' bits, one bit per channel
WY - Word (Analog)
Outputs (16-bit signed) - for example 4WY = 4 Word (Analog) Outputs
X Map - this column displays
the current I/O Addressing assignment for the Discrete Input module in
that slot
Y Map - this column displays
the current I/O Addressing assignment for the Discrete Output module in
that slot
WX Map - this column displays
the current I/O Addressing assignment for the Word (Analog) Input module
in that slot
WY Map - this column displays
the current I/O Addressing assignment for the Word (Analog) Output module
in that slot
