Configuring SLC 500 Processors with 1747-KE Interface Modules 5-15

Note that the SLC 5/02 station address 99

in this example is station

address 143

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

is issuing a read command,

through a 1747-KE module whose DH-485 node address is 11

, to a

PLC-5 station. The SLC 5/02 station (station 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.)
