1-6 Hardware Overview
Communication Options The MicroLogix 1500 can be connected to a personal computer. It can
also be connected to the DH-485 network using an Advanced
Interface Converter (1761-NET-AIC), to an Ethernet network using an
Ethernet Interface (1761-NET-ENI), or to a DeviceNet™ network using
a DeviceNet Interface (1761-NET-DNI) or through the DeviceNet
Scanner module (1769-SDN). The controller can also be connected to
Modbus™ SCADA networks as an RTU slave. See Communication
Connections on page 4-1 for more information on connecting to the
available communication options.
The 1764-LRP processor provides an additional communication port.
Each of the communications ports can be independently configured
for any supported communication protocol. (Channel 0 is on the base
unit and Channel 1 is on the 1764-LRP processor.)
Compact™ Expansion I/O Compact expansion I/O (Bulletin 1769) can be connected to the
MicroLogix 1500 Controller. A maximum of either 8 or 16 expansion
I/O modules can be used, depending upon your system. See System
Requirements for Using Expansion Modules on page 1-7.
See System Loading and Heat Dissipation on page F-1 for more
information on system configurations.
End Cap
An end cap terminator (catalog number 1769-ECR or 1769-ECL) must
be used at the end of the group of I/O modules attached to the
MicroLogix 1500 Controller. The end cap terminator is not provided
with the base or processor units. It is required when using expansion
I/O.
This illustration shows the right end cap (1769-ECR ). The left end cap
(1769-ECL) is shown on page 1-10.
