We are witnessing the increasing take-up of IE (Industrial Ethernet) as engineers continue leveraging the benefits of network connectivity over traditional hardwired networks. The trick, however, has been achieving IE connectivity in a cost-effective and simple way. For those tasked with finding a cost-effective means of connecting valve systems to IE, Parker's new network node can provide a solution.
The need for connectivity largely results from the potential for real-time control of manufacturing processes, which in turn captures and generates data to aid the implementation of predictive maintenance strategies and make decisions based on shop-floor trends. Several IE protocols such as Profinet, Ethernet /IP, EtherCAT and others are introduced and widely adopted due to their advantages over traditional fieldbus networks. You will probably not be surprised to learn that IE protocols are today the fastest growing deployed network type in new industrial installations with an annual growth rate of 22 percent.
IE become popular thanks to the availability of several protocols, broad market acceptance, a good degree of backwards compatibility and the availability of rugged components (hardwired) which are typically protected from electrical noises.
Parker network connectivity options
Parker’s global focus on factory automation means has resulted in an extensive range of network connectivity options with the addition of a cost-effective IE node. The new P2M IE node provides an inexpensive means of connecting Moduflex Valves, H Series ISO valve and H Micro valve families to IE. P2M IE node is intuitive, and easy to use, install and maintain. Moreover, the network node is safe-power capable, meaning auxiliary valve power can be supplied by a safety device in support of the European Machinery Directive. This capability allows for test-pulse (OSSD) compatibility and can be supplied with auxiliary power from a safe output device, such as a safe relay or a remote safe DO module.
With the P2M IE node, simple diagnostic input data is provided over the network for easy troubleshooting and predictive maintenance. There are useful diagnostic flags in process (cyclic) data for easy access, including voltage and temperature warnings, communication error and solenoid short-circuit error. This is complemented by detailed diagnostic information in parameter (acyclic) data, such as voltage readings, configuration options and cycle count for each solenoid.
Low-cost connectivity with integrated diagnostics is at last a reality, further reducing complexity and cost at the machine, while aligning with the needs and objectives of smart factory and Industry 4.0 objectives.
Today Parker offers a full range of IE connectivity options, including EtherNet/IP, Profinet IO, EtherCAT, Ethernet PowerLink, Modbus TCP/IP and CC-Link IE protocols.
