Rockwell Automation 57C442 Data Highway Plus Interface Module - Manual (Page 8)

1-2
Each AutoMax Processor has access to the look-alike PLC-5 or SLC
registers through the AutoMax rack backplane. The Data Highway Plus
Interface module transfers data between the PLC-5 look-alike image
and remote Allen-Bradley equipment using the Word Range Read,
Word Range Write, and Read-Modify-Write commands. The module is
capable of responding directly to these commands as well as typed
read and write commands from the PLC-5 command set and eight
other commands from the basic command set. These commands are
described in section 4.2. The individual command formats are
described in the various Allen-Bradley instruction manuals.
The remainder of this manual describes the functions and
specifications of the Data Highway Plus Interface module. It also
includes a detailed description of module installation and
troubleshooting procedures, as well as programming methods.
