Discrete I/O Assignments

This chapter provides detailed information about the discrete inputs and
outputs that connect the CVIM2 system to the user’s process control
equipment through the

Module I/O

System I/O

, and

Remote I/O

ports on

the CVIM2 module front panel. This chapter also includes the procedures for
assigning signals to the discrete inputs and outputs, the front panel LEDs and
the remote I/O inputs and outputs.

The

Module I/O

port contains two input and 14 output lines, while the

System I/O

port contains 16 discrete lines that the user can select as inputs

or outputs. The front panel contains two user–assignable status LEDs. The

Remote I/O

port provides 120 inputs to the CVIM2 from a PLC

, and 128

outputs to a PLC (the CVIM2 appears to a PLC as a full 8–slot rack on the
remote I/O line).

The discrete I/O assignments are performed in the

Discrete I/O Editor

panel. When you pick

Discrete I/O

in the

Editors

menu of the main menu

bar, the

Discrete I/O Editor

panel appears, as shown in Figure 9.1.

editors, and there are differences in the types

of signal functions that you can assign, accordingly. These differences are
pointed out later in this chapter.
