Chapter 1 Analog I/O Module Operation in a Logix5000 Control System
Ownership
Every I/O module in a Logix5000 control system must be owned by a controller,
also known as the owner-controller. When the 5069 Compact I/O analog I/O
modules are used in a Logix5000 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 5069 Compact I/O system.
• Sends the I/O module configuration data to define module behavior and
begin operation in the control system.
Each 5069 Compact I/O analog I/O module must continuously maintain
communication with its owner-controller during normal operation. The 5069
Compact I/O analog I/O modules are limited to one owner-controller that
performs the functions that are listed previously. Other controllers can establish
Listen-Only connections to the 5069 Compact I/O analog I/O modules.
If necessary, different Logix5000 controllers can own different 5069 Compact
I/O modules that reside in the same chassis. For example, one 1756-L85E
controller can operate as the owner-controller for a 5069 Compact I/O module
in slot 1 of a 5069 Compact I/O system. Another 1756-L85E controller can
operate as the owner-controller for a 5069 Compact I/O module in slot 2 of the
same 5069 Compact I/O system.
Construct a 5069 Compact
I/O System
At minimum, the system must include a 5069-AEN2TR EtherNet/IP adapter.
The system can contain other 5069 Compact I/O modules, for example, 5069
Compact I/O analog input modules.
Figure 2 shows the owner-controller in a 1756 ControlLogix chassis that is
connected to the 5069 Compact I/O modules via an EtherNet/IP network.
