text: <s>[INST] Kinetix 5100 to DeltaV (PK Controller) explicit messaging Hi all, We are working with a Kinetix 5100 drive which we want to connect to a DeltaV system using a PK controller through Ethernet IP, the drive will be used to control the speed of a pump for a bag and bottle filler, previously in a past project it was used the Kinetix 300 but since it'll be discontinued, we were told to use Kinetix 5100 instead, Kinetix 5100 manual indicates that we can use same explicit class 3 messaging like Kinetix 300 to communicate with DeltaV but the Input and Output assembly data shown in the manual says that is intended to use only with IO mode (Class 1 Ethernet/IP connection). Does anyone know how or where to find the Input and Output assembly data when using Class 3 explicit messaging? Any help would be appreciated. Thanks in advance Edgar V [/INST] Hello, you can perform Class 3 Messaging to an external device only. The I/O assemblies are only available using a Logix based controller as you mention. You can use the example MicroLogix 1400 or Micro800 Class 3 messaging examples on the SampleCode Library (or available from your local Rockwell Automation Tech Specialist or distributor). These examples show how you can get some meaningful (but not as rich as the I/O assemblies) information passed between the controller and drive. Hope that helps. \\n </s>
