GE Intelligent Platforms's PACSystems High Availability with PROFINET System enables companies with mission critical applications to maximize uptime, capitalize on flexible configurations no matter the distance between CPUs and I/O drops, and fully utilize the intelligence that exists in their systems for faster decision-making. The new system’s high availability architecture includes PROFINET communications to dramatically lower total cost of ownership and simplify configuration, maintenance and operation of mission critical facilities and operations.


PACSystems High Availability with PROFINET provides a single point of connect for system configuration. All remote I/O nodes, whether they are 100 meters or up to 10kms from the controllers, can be configured from one central location. With built-in Ethernet switches and built in media conversion, the solution provides for point-to-point plug-in connectivity. Removing the need for external media converters and Ethernet switches results in reduced cost and setup time. In addition, the user can employ their cable of choice on a node-by-node basis based on the environment and distance, which also reduces the setup time. Also essential to reducing setup time is the system’s name based configuration. This feature allows a user to set up a system, mirror it with a command to the second CPU and then they are good to go.

The system’s high speed failover feature is especially important in a process where “stale data,” data that is not inclusive of everything that has happened in the process because a sensor did not read while the process was switching CPUs, could mean a breakdown that resulted in contaminated product – water, oil, gas, etc. High speed failover means that the user is running on latest system inputs, which translates to better production quality.

Users can conduct system maintenance without taking the system offline, saving time and money, and can schedule device checking, such as a valve not opening correctly based on flow commands, without taking the entire pipeline control down. Flexible diagnostics supply important data regarding the network topology and the status of all devices. This facilitates cross-vendor, location-specific diagnostics and connects to the Proficy Software suite for turning data into information.
