6-20 Configuring MicroLogix 1000 Controllers
Figure 6.6 Read MSG Instruction from a MicroLogix 1000 Controller to a PLC-5
Processor
In this example, MicroLogix 1000 station 10
10
is issuing a read
command to a PLC-5 station. The MicroLogix 1000 station (station
10
10
) reads the information in N10:10-N10:15 of the PLC-5 station and
puts that information into its N7:10-N7:15.
For example, if the MicroLogix 1000 controller in this example is
station 10
10
, then it reads the data from N10:10-N10:15 in the PLC-5
processor. File N10 must exist in the PLC-5 in order for the
MicroLogix
1000 controller to read data from it.

IMPORTANT
The MicroLogix 1000 controller reads the information
from an integer file in the PLC-5 processor’s data
table that corresponds to the MicroLogix 1000
controller’s station address (this event is called PLC-2
emulation).
