5-16 Configuring SLC 500 Processors with 1747-KE Interface Modules

For example, if the SLC 5/02 processor in this example is station 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 SLC 5/02 processor to

read data from it.

For an example write MSG instruction from an SLC 5/02 processor to a

PLC-5 processor, see

Figure 5.7 on page 5-14. The MSG control block

is configured the same regardless if the message is being sent from an

SLC 5/02 remote station to a PLC-5 master station or an SLC 5/02

processor and a PLC-5 processor that are communicating in a

point-to-point configuration.

Figure 5.9 Write MSG instruction from an SLC 5/02 processor to an SLC 500

processor.

In this example, SLC 5/02 station 3 is issuing a write request, through

a 1747-KE module whose DH-485 node address is 13

, to an SLC

5/03 processor.

Station 3 wants to write the information from its S:1 to S:6 into the

SLC

5/03 processor’s data files N9:0 to N9:5.
