2.2.1 Optional expansion modules
The controller is available with optional expansion modules:
• Profibus DP interface module (Slot 0)—Used to connect the controller to a Profibus DP
(decentralized peripherals) network. Profibus DP is used to operate sensors and actuators with a
centralized controller in production (factory) automation applications.
• 4–20 mA output module (Slot 1)—Used for analog signaling or to control other external devices.
Note: Only one 4–20mA output module can be installed.
• EtherNet/IP module (Slot 2)—The controller can connect to a PLC through Industrial Ethernet
Protocol including a EtherNet/IP solution. Line, Star and Ring topologies are available.
• PROFINET module (Slot 2)—The controller can connect to a PLC through the Industrial Ethernet
Protocol, which includes a PROFINET solution. Line, Star and Ring topologies are available.
• 4–20 mA input module (Slot 3 or 4)—Lets the controller accept one analog input (0–20 mA or
4–20 mA) from an external device.
• pH/ORP module (Slot 3 or 4)—Lets the controller accept measurements from one pH or ORP
analog sensor.
Note: An expansion module can be installed in only one of Slots 0 ,1 and 2 (4–20 mA output, Profibus DP interface,
PROFINET or EtherNet/IP).
Note: Only two input devices
6
can be connected to the controller at the same time. If more than two input devices
are connected, the controller will only see two of the devices. Refer to the module documentation for additional
information.

Dependent on controller configuration. The expansion modules are factory-installed based on
controller configuration.
6
Input devices are analog inputs from external devices, analog sensors and digital sensors.
