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.
