Interfacing the ControlLogix PLC over Ethernet/IP
نویسندگان
چکیده
The Allen-Bradley ControlLogix [1] line of programmable logic controllers (PLCs) offers several interfaces: Ethernet, ControlNet, DeviceNet, RS-232 and others. The ControlLogix Ethernet interface module 1756-ENET uses EtherNet/IP, the ControlNet protocol [2], encapsulated in Ethernet packages, with specific service codes [3]. A driver for the Experimental Physics and Industrial Control System (EPICS) has been developed that utilizes this EtherNet/IP protocol for controllers running the vxWorks RTOS as well as a Win32 and Unix/Linux test program. Features, performance and limitations of this interface are presented.

The fieldbus systems have been successfully introduced in the industrial automation. Nowadays, a large community is inventing the usage of Ethernet-based local communication systems in this domain ensuring the realtime behaviour of these systems. Profinet IO provides the service definition and protocol specification for real-time communication based on Ethernet, IP, and UDP for the field area. ...
متن کاملPLC and SONET/SDH Networks Bridging with Ethernet
Power Line communications (PLC) provides “Broadband Ethernet” connectivity directly to the customer’s socket in home without additional cabling. However, PLC networks do not provide global end-to-end connectivity and need to rely on incumbent’s telecom networks. In order to lower the cost of CAPEX and OPEX the network interconnection is done at “Ethernet” level. Most of Incumbent’s networks are...
متن کاملNetwork Working Group Transmission of Ip over Ethernet over Ieee 802.16 Networks
This document describes the transmission of IPv4 over Ethernet, as well as IPv6 over Ethernet, in an access network deploying the IEEE 802.16 cellular radio transmission technology. The Ethernet on top of IEEE 802.16 is realized by bridging connections that IEEE 802.16 provides between a base station and its associated subscriber stations. Due to the resource constraints of radio transmission s...
متن کاملInterfacing Fast Ethernet to Processors
Ethernet has dominated due to the ease-of-use and open standard approach providing true interoperability between equipment in the field. By itself, Ethernet is not strictly a protocol yet it provides the lower ‘hardware’ layers for the higher layer software stacks such as TCP/IP or UDP. So, it would seem the task to network a device should be as simple as ‘bolting on’ an Ethernet transceiver an...
