Ladder Logic Programming—Including Reading Inputs

ControlLogix Programming Example

Unlike PLC and SLC programs, the ControlLogix utilizes a tag-based
technique.

A ControlLogix is used to read 2100-GK61 inputs and control the
outputs of an SMP-3 electronic overload relay.

Rungs 0 through 3 illustrate XIC (Examine if Closed) input
instructions. Each 2100-GK61 input can be read by examining
Scanner in slot 1. Therefore, the first input is Local:1:I.Data[0].0. The
second input is located at Local:1:I.Data[0].1. In this example, status
of each 2100-GK61 input is annunciated by the first four bits of the
output card in slot 2. The first output is addressed as
Local:2:O.Data.0.

Rung 4 enables the Scanner.
