Use Cases and Applications
The 22-COMM-E module is typically employed in distributed control systems, factory automation, and legacy PLC upgrades. Its dual-interface design allows it to:
-
Connect older PLCs to EtherNet/IP networks.
-
Facilitate communication between serial devices and modern automation controllers.
-
Serve as a gateway for integrating disparate devices into a single network for monitoring and control.
Industries like packaging, material handling, and process automation often utilize this module for bridging equipment from multiple generations.
Key Advantages
-
Flexible Connectivity: Supports both serial and Ethernet communication, easing integration.
-
Easy Deployment: Plug-and-play setup with minimal configuration effort.
-
Diagnostic Support: LED indicators provide real-time operational feedback.
-
Durable Design: Industrial-grade housing ensures stability under vibration and temperature fluctuations.
-

Technical FAQs
-
Which protocols can 22-COMM-E handle simultaneously?
EtherNet/IP on RJ45 and DF1 serial or Modbus TCP, depending on configuration. -
Can it operate with multiple PLCs?
Yes, but each network must be properly segmented and addressed. -
Is the module hot-swappable?
No, power should be removed before installation or removal. -
What is the maximum cable distance for serial communication?
Up to 15 meters (50 feet) using standard RS-232 cables; longer distances require RS-485. -
Does it provide diagnostic feedback for network faults?
Yes, LEDs indicate link, activity, and fault states. -
Can firmware be updated in the field?
Yes, via Ethernet connection using Rockwell configuration tools. -
Is galvanic isolation provided between interfaces?
Yes, isolation protects connected devices from voltage spikes. -
Can it be used in a harsh industrial environment?
Yes, rated for 0–60°C operation with non-condensing humidity up to 95%. -
Does it require a separate power supply?
It draws power directly from a 24 VDC source. -
Is it compatible with ControlLogix and CompactLogix controllers?
Yes, fully supported when integrated via Ethernet/IP or DF1 links.
