Compact 5000 I/O Serial Module
Compact 5000 I/O Serial
Module Overview
The Compact 5000™ I/O serial module provides two independent channels
that function as network interfaces to a wide variety of RS-232C, RS-422, and
RS-485 devices.
The module has two channels that are independent of each other. The channels
can transmit data to and receive data from serial devices using the following
communication mode:
• Generic ASCII
•ModbusRTU(Master/Slave)
• Modbus ASCII (Master/Slave)
The serial module can reside locally in a CompactLogix™ 5380 system or a
Compact GuardLogix® 5380 system. The module can also reside in a remote
Compact 5000 I/O system accessible via an EtherNet/IP network.
For more information on how a Compact 5000 I/O serial module can function
in a control system, see Chapter 2, Compact 5000 I/O Serial Module
Operation in a Logix 5000 Control System.
IMPORTANT Use Studio 5000 Logix Designer® Version 31 or greater. You must install an
Add-On Profile to use the serial module. To find the Add-On Profile go to the
Product Compatibility and Download Center (PCDC).

Local I/O or Remote
I/O Modules
You can use a Compact 5000 I/O Serial module as a local or remote I/O
module.
Local I/O Module
When Compact 5000 I/O Serial module resides in the same system as the
controller, it is a local I/O module. Local I/O modules are installed to the right
of the controller and exchange data with the controller over the system
backplane.

Remote I/O Module
When a Compact 5000 I/O Serial module resides in a separate location from
the controller, it is a remote I/O module. Remote Compact 5000 I/O modules
are accessible over an EtherNet/IP network via a Compact 5000 I/O
EtherNet/IP adapter.
Remote Compact 5000 I/O modules are installed to the right of the adapter
and exchange data across the remote system backplane. The data is exchanged
with the controller over the EtherNet/IP network.

Chapter 2 Compact 5000 I/O Serial Module Operation in a Logix 5000 Control System
Ownership Every I/O module in a Logix 5000 control system must be owned by a
controller, also known as the owner-controller. When the Compact 5000 I/O
modules are used in a Logix 5000 control system, the owner-controller
performs the following:
• Stores configuration data for every module that it owns.
• Can reside in a location that differs from the Compact 5000 I/O system.
• Sends the I/O module configuration data to define module behavior
and begin operation in the control system.
Each Compact 5000 I/O serial module must continuously maintain
communication with its owner-controller during normal operation.
Construct a System That Uses
a Compact 5000 I/O Serial
Module
Before you use your serial module, you must complete tasks based on the way
that you use the modules:
• Local I/O modules - Complete the following:
a. Install a controller that can use the serial modules local I/O modules.
b. Install the serial module to the right of the controller.
• Remote I/O modules - Complete the following:
a. Install an adapter that is compatible with remote
Compact 5000 I/O standard and/or safety modules via an
EtherNet/IP network.
b. Install the serial module to the right of the adapter.
c. Install an EtherNet/IP network.
d. Install the controller that accesses the serial modules via an EtherNet/
IP network.

Power Compact 5000 I/O
Serial Module
Compact 5000 I/O serial modules receive the following power types:
• System-side Power - Powers the system and lets modules transfer data
and execute logic.
System-side power is also known as MOD power.
• Field-side Power - Powers field-side devices that are connected to some
Compact 5000 I/O modules.
Field-side power is also known as SA power.
Power begins at the left-most device in the system and passes across the
Compact 5000 I/O module internal circuitry via power buses, that is, a MOD
power bus. The left-most device is either a controller or an EtherNet/IP
adapter, depending on whether the Serial module is a local or remote I/O
module.
For more information on how to power local Compact 5000 I/O
modules, see the CompactLogix 5380 and Compact GuardLogix 5380
Controllers User Manual, publication 5069-UM001.
For more information on how to power remote Compact 5000 I/O
modules, see the EtherNet/IP Communication Modules in 5000 Series
Systems User Manual, publication ENET-UM004.
IMPORTANT The Compact 5000 I/O Serial Module does not use SA power.
However, verify that the module is installed in a position where SA
power uses DC voltage.
IMPORTANT Remember the following:
• A system uses only one MOD power bus that starts at a
controller or adapter and passes across all modules installed in
the system.
• A system can use more than one SA power bus. The first SA
power bus typically starts at the controller or adapter, and 5069-
FPD field potential distributors let you establish new SA power
buses in the same system.

Configure Compact 5000 I/O
Modules
You must create a Logix Designer application project for the Logix 5000
controller that owns the Compact 5000 I/O Serial modules. The project
includes module configuration data for the Compact 5000 I/O Serial module.
The Logix Designer application transfers the project to the owner-controller
during the program download. Data is then transferred to the Compact 5000
I/O Serial module either across the backplane or over an EtherNet/IP
network.
The Compact 5000 I/O modules can operate immediately after receiving the
configuration data.
Connections
During module configuration, you must define the module. In the Module
Definition parameters for most Compact 5000 I/O modules, you must choose
a Connection type. A connection is a real-time data transfer link between the
owner-controller and the module that occupies the slot that the configuration
references.
When you download module configuration to a controller, the controller
attempts to establish a connection to each module in the configuration.
Because part of module configuration includes a slot number in the local
CompactLogix 5380 or Compact GuardLogix 5380 controller system or
remote Compact 5000 I/O system, the owner-controller checks for the
presence of a module there. If a module is detected, the owner-controller sends
the configuration. One of the following occurs:
• If the configuration is appropriate to the module detected, a connection
is made and operation begins.
• If the configuration is not appropriate to the module detected, the data
is rejected and the Logix Designer application indicates that an error
occurred.
The configuration can be inappropriate for many reasons. For example, a
mismatch in electronic keying that helps prevent normal operation.
The owner-controller monitors its connection with a module. Any break in the
connection, for example, the loss of power to the Compact 5000 I/O system,
causes a fault. The Logix Designer application monitors the fault status tags to
indicate when a fault occurs on a module.

Multiple Connections to One Serial Module
Unlike other Compact 5000 I/O modules that make one connection to the
owner-controller, the Compact 5000 I/O Serial module can have multiple
connections based on how the module channels are configured.
The Serial module is required to use the Data connection type in the Module
Definition dialog box. However, the module has two channels that you must
configure independently of each other. You can disable a channel or choose a
mode, that is, the Generic ASCII, Modbus Master, or Modbus Slave mode.
The combination of channel configuration choices determines the number of
connections that are made between the owner-controller and the Serial
module.
For example, consider the following examples:
• Channel 0 = Generic ASCII, Channel 1 = Modbus Slave - Two
connections are made between the owner-controller and the module.
Selected Protocol Description
Generic ASCII The module returns the following to the owner-
controller:
• General fault data
• Input Data
•OutputData
Modbus Master The module returns the following to the owner-
controller:
• Generic fault data
• Last executed command data
•Input/Output
•Operationstatus
Modbus Slave The module returns the following to the owner-
controller:
• Generic fault
• Slave input data
•Slaveoutputdata
