Modbus TCP and PCCC Register Map. They are determined from the corresponding
Modbus TCP registers as follows:

Take the Modbus TCP register of interest, ignore the leading 4 and divide
by 100. The quotient is the register file (prefixed with N) and the
remainder is the register number.

For example, to read Modbus TCP register 42,001 (Sensor Value), ignore the leading 4 to
obtain 2,001, and divide 2,001 by 100 to obtain 20 with a remainder of 1. The register
file, then, is N20 and the register is 1, or N20:01.

Keep in mind that there is no type checking; if you access only N20:01 instead of N20:01
and N20:02 you will receive a strange number because N20:01 is only half of the data for
a floating-point value.

Please note that PLC Data Type (N30:25) has no effect on the order of the bytes or words
transferred using PCCC.

For a detailed explanation of the PCCC register contents, please see the description of the
associated DataStick Command in the DataStick Measurement System Instruction
Manual, Catalog Number MAN011DS-4.

7.2.1 SLC 5/03 and SLC 5/04 PLCs

If you have an Allen-Bradley SLC 5/03 or SLC 5/04 PLC and wish to communicate with
an Ethernet Communications product you’ll need a 1761-NET-ENI MicroLogix™
Ethernet Interface (ENI) and a 1761-PM02-CBL Communications Cable (Catalog No.
2707-NC8) to add Ethernet connectivity to the SLC. Figure 50 shows a SLC 5/03
connected to an Ethernet network via a 1761-NET-ENI.

Figure 50: SLC 5/03 PLC connected to Ethernet network via a 1761-NET-ENI.

The SLC communicates with the ENI using DF1 full-duplex over RS-232 and the ENI
translates the communications into EtherNet/IP and sends them out on the Ethernet
network.

7.2.1.1

Configuring the NET-ENI

The 1761-NET-ENI (ENI) must be configured to forward messages from the SLC to the
Ethernet Communications product before you can accomplish any communications. This
