Parker Hannifin releases LINKnet Communications for VFDs

July 28, 2014--Parker Hannifin releases LINKnet Communications for VFDs. LINKnet is an Ethernet based version of the SSD LINK system that has been successfully used in coordinated drive systems for 25 years. It is a peer-to-peer network designed to integrate AC and DC drives with remote I/O at high speed, with or without a supervisory PLC, allowing precise and repeatable control for complex machines and process lines. LINKnet nodes communicate using Modbus TCP over Ethernet.

LINKnet components are plugin compatible with many older Parker SSD brand drives. An existing LINK system using AC690+ and/or DC590+ units can potentially be updated to LINKnet without requiring the replacement of functional drives. The system will connect to any Ethernet enabled PLC and with remote I/O. LINK2 touchscreens can be replaced by the Parker TS8000.

Three varieties of LINKnet tech boxes are available, including direct plug-in modules for all frame sizes of AC690+ and DC590+, and a stand-alone DIN rail variant for interfacing with other devices. LINKnet tech boxes are connected by commercially available CAT-6 Ethernet cable, and require no external source of power when installed on an AC690+ or DC590+ drive.

Parker has qualified third party remote fieldbus I/O modules for use in LINKnet systems. This provides users with an assortment of standard modules to choose from. Digital, analog and specialty modules may be combined, up to 64 per node, and will be recognized and supported by Parker DSE software.
