5-14 Configuring SLC 500 Processors with 1747-KE Interface Modules
Figure 5.7 Write MSG instruction from an SLC 5/02 processor to a PLC-5 processor.
This MSG example is telling the SLC 5/02 remote station (station 99
10
)
to write the information from its S:1 to S:6 to the PLC-5 master station
9
10
through the KE module 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 SLC 5/02 processor in this example is station 99
10
,
then it writes the data from its S:1 to S:6 into N99 of the PLC-5 master
station. File N99 must exist in the PLC-5 in order for it to receive data
from the SLC 5/02 remote station.

IMPORTANT
The SLC 5/02 processor writes the information into
an integer file in the PLC-5 processor’s data table.
The integer file number is equal to the SLC 5/02
processor’s station address. (This event is called
PLC-2 emulation.)
