Using the RS1 Module with a Programmable Controller 8–3

Program the Ladder

The example ladder program in Figure 8.2 demonstrates writing a

Logic Command to the drive and reading the Logic Status from the

drive.

In the following example ladder program, B3:0/0 is set every 2

seconds. This enables a Logic Command write to be done followed

by the Logic Status read. The data for the Logic Command is stored

in N7:8 of the MicroLogix and is written to location N41:0 of the RS1

Module. For the Logic Status, data from the RS1 Module at location

N41:0 is read by the MicroLogix and stored in N7:9. This ladder

program could be modiﬁed to read and write speed commands for the

160 Drive by changing the read and write location in the RS1 Module

from N41:0 to N41:1.
