Alongside these technology demonstration, the ODVA stand will feature a Members Products Area, featuring all the latest products from participating members, based on CIP - the 'Common Industrial Protocol' the technology that underpins DeviceNet and EtherNet/IP.
The debut of the recently announced safety extensions to CIP, DeviceNet Safety provides fail-safe communication between nodes such as safety I/O blocks, safety interlock switches and safety light curtains.
While at the same time the DeviceNet Safety unified solution lets you implement Standard Devices together with these Safety Devices on the same wire, with or without the need for a Safety PLC, resulting in reduced engineering and installation cost, improved diagnostics and increased architectural flexibility.
CIP Sync, meanwhile, provides a set of time synchronisation services for DeviceNet and EtherNet/IP, delivering assured time synchronisation of devices and controllers across these networks.
This is important in areas such as distributed motion control or event recording applications, or indeed any installation requiring enhanced control coordination.
CIPsync is based on the recently announced IEE-1588 standard - Precision Clock Synchronisation Protocol for Measurement and Control Systems - which is designed for local area networks like Ethernet that support multicast messaging.
This profile matches ODVA CIP-based, producer/consumer networks, making the time synchronisation standard ideally suited to both DeviceNet and EtherNet/IP.
Using a 100Mbps switched Ethernet system, testing has shown that CIPsync can deliver time synchronisation accuracy of less than 500 nanoseconds between devices - the benchmark standard for critical real-time applications.
As well as the technology demonstrations, visitors to the ODVA Europe stand will also be able watch presentations - in both English and German - explaining the benefits in adopting products based on ODVA technology.
