Unique Redundancy Methodology Introduction to Redundancy

Unlike other SIS Logic Solvers, the SLS 1508 is rated suitable for use in SIL 3 applications in simplex mode.

Redundant SLS 1508 Logic Solvers run in parallel at all times. 

Both read the inputs from the I/O terminals, both execute the logic and both drive the outputs at the I/O

terminals. There is no concept of primary and backup or master and slave, which is unlike any other SIS. 

The only difference between the two is that one communicates with both the engineering and operator workstations 

and the dedicated safety network (SISnet); this is the one with the Active light on the bezel. 

The other (Standby) is communicating only on the SISnet.

In the event that a failure is detected in one of the SLS 1508 Logic Solvers, it automatically goes to a failed state.

In this condition all its output channels are de-energized; 

this has no impact on the other Logic Solver or the physical outputs because the other Logic Solver continues

to read inputs, execute logic and drive outputs. The transition from redundant to simplex mode is therefore completely bumpless.

PK Controller: Now Supporting Native PROFINET

PROFINET is an open industrial Ethernet solution and is based on international standards. 

It is a communication protocol designed to exchange data between controllers and devices in an industrial automation network.

And now, both the innovative PK Controller and new PK Flex Controller support native PROFINET, 

helping customers enhance their performance and meet the requirements of most of their time-critical applications.

You do not need special hardware or configuration to use PROFINET; 

the PK Flex Controller and PK Controller are equipped with PROFINET capability.

„ PK Flex Controller is a PROFINET controller and will connect with up to 250 devices such as PLCs, Drives,Remote I/O, transmitters and valves.

„ PROFINET in the PK Flex Controller is compliant with version 2.3 and CC-A functionality.

The Ovation I/O modules are locked into base units. These base units are housed in

the Controller cabinets where they are mounted on DIN rails and wired to the

appropriate field devices.

The standard modular components typically consist of the following:

• Electronics module

• Personality module

• Base Unit (containing the field terminations)

The relay output modular components consist of the following:

• Electronics module

• Base Unit (containing the field terminations)

DeltaV Live: New Web Displays

DeltaV Live provides the flexibility to easily and securely integrate process information from many different sources

into a single HMI environment, providing an intuitive and cohesive view into your operations. 

New Web Displays allow users to securely view web content as operator graphics, making it even easier to expand operator visibility and

awareness within the DeltaV Live HMI.

Web Displays behave as any other dedicated operator graphic. 

They can be included in display sets,participate in hierarchical display navigation, and have a dedicated display frame in a layout. 

An intuitive toolbar is also included for easy navigation and zooming.
