Configuring SLC 500 Processors with 1747-KE Interface Modules 5-15
Note that the SLC 5/02 station address 99
10
in this example is station
address 143
8
, which is derived by a DH-485 node address of 03 for the
SLC 5/02 processor and a group number of 03 defined in the 1747-KE
interface module.
Figure 5.8 Read MSG instruction from an SLC 5/02 processor to a PLC-5 processor.
In this example, SLC 5/02 station 10
10
is issuing a read command,
through a 1747-KE module whose DH-485 node address is 11
10
, to a
PLC-5 station. The SLC 5/02 station (station 10
10
) reads the
information in N10:10 to N10:15 of the PLC-5 station and puts that
information into its N9:0 to N9:5.

IMPORTANT
The SLC 5/02 processor reads the information from
an integer file in the PLC-5 processor’s data table that
corresponds to the SLC 5/02 processor’s station
address. (This event is called PLC-2 emulation.)
