Emerson Ovation 5A26420G12 Operator Keyboard Kit

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.

DeltaV™ Version 15 continues to set the pace in shaping the future of automation with Feature Pack 1 updates.

When it comes to preparing operations with future-proof automation technologies that not only propel performance

and production but help to accelerate digital transformation, DeltaV Version 15 Feature Pack 1 provides a collection of

updates and new functionality that deliver.

PK Flex Controller

The DeltaV PK Flex Controller builds upon the ground breaking innovation and technology of the PK Controller.

It provides the same powerful functionality but with the added advantage of flexible capacity and a subscription

based license that will help reduce capital costs.

The DeltaV PK Flex Controller is configured like any other controller in a DeltaV system and can be installed as simplex

or redundant node. It can be used for applications in a wide variety of sizes, from 50 to 1500 Flex DSTs, depending on

which capacity customers subscribe to. For Ethernet-APL Device Control, 

the DeltaV PK Flex Controller can be used for a variety of Ethernet-APL Devices, supporting Modbus

TCP client or EtherNet/ IP interface in port P01 and PROFINET(PN1). 

P01 and PROFINET (PN1) can be enabled at the same time for greater functionality

System Configurations

The Mini Converter can be used in a point-to-point configuration as described above,

or in a multidrop configuration with the host device configured as the master and one or more programmable controllers configured as slaves.

The multidrop configuration requires a straightthrough (1-to-1) cable from the Mini Converter’s RS-422 port to the first slave PLC’s SNP port.

Other slaves will require a daisy chain connection between slaves.

A maximum of eight devices can be connected in an RS-422 multidrop configuration.

All of the devices must have a common ground.

If ground isolation is required, you can use the Isolated Repeater/Converter (IC655CCM590) in place of the Mini Converter.

When using the Mini Converter with a modem connection,

it may be necessary to jumper RTS to CTS (consult the user’s manual for your modem).

Cable Diagrams (Point-To-Point) When connecting the Mini Converter to IBM PC and compatible computers with hardware handshaking,

the following cable connections should be used.

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)
