Configuring MicroLogix 1000 Controllers 6-19
Figure 6.5 Write MSG Instruction from a MicroLogix 1000 Controller to a PLC-5
Processor
This MSG example is telling the MicroLogix 1000 station (station 99
10
)
to write the information from its N7:10-N7:15 to the PLC-5 station 31
10.
The data’s destination is N99:10 (for a target byte offset of 20
10
) of the
PLC-5 processor.
For example, if the MicroLogix 1000 controller in this example is
station 99
10
, then it writes the data from its N7:10 - N:15 into N99 of
the PLC-5 station. File N99 must exist in the PLC-5 in order for it to
receive data from the MicroLogix 1000 station.

IMPORTANT
The MicroLogix 1000 controller writes the
information into an integer file in the PLC-5
processor’s data table. The integer file number is
equal to the MicroLogix 1000 controller’s station
address (this event is called PLC-2 emulation).
