Ladder Logic Programming—Including Reading Inputs 5-17

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.
