Ethernet I/O Modules

Acromag's Ethernet/IP, Modbus TCP I/O, and Profinet products offer a variety of solutions for remote I/O, distributed process control, and factory automation applications. Analog and discrete Ethernet I/O modules interface sensors and actuators to controllers with Modbus TCP/IP or Ethernet/IP CIP protocol network communication. EtherNet/IP (Ethernet Industrial Protocol) is traditional Ethernet combined with an industrial application layer protocol targeted to industrial automation. This application layer protocol is the Control and Information Protocol (CIP™). EtherNet/IP was created in an attempt to overcome the shortcomings of traditional IEEE 802.3 Ethernet as applied to the industrial automation world.

More Ethernet I/O Modules Information

Modbus TCP/IP uses TCP/IP and Ethernet to carry the data of the Modbus message structure between compatible devices. That is, Modbus TCP/IP combines a physical network (Ethernet), with a networking standard (TCP/IP), and a standard method of representing data (Modbus as the application protocol). Essentially, the Modbus TCP/IP message is simply a Modbus communication encapsulated in an Ethernet TCP/IP wrapper.

Profinet controllers are programmed with a special Profinet Configuration tool, like the Step7 from Siemens.

CE compliant. UL/cUL Class 1 Div 2 Zone 2 approvals. ATEX Certified.
