Generic Device EtherNet/IP Scanner Driver for DeltaV VIM2
By Jake Nichelson
Product: IOD-4114 - Generic Device Ethernet IP Scanner Driver for DeltaV VIM2

This driver for the DeltaV Virtual IO Module 2 (VIM2) provides native integration to devices that use the Common Industrial Protocol (CIP) defined in the EtherNet/IP Specification from the Open DeviceNet Vendor Association (ODVA).

Using the Generic Device EtherNet/IP Scanner Driver, DeltaV Controllers can read and write signals from plant floor devices that support EtherNet/IP, such as PLCs, Motor Control Centers, and Weigh Scales, using native DeltaV IO structures.

Key Features of the Generic Device EtherNet/IP Scanner Driver for VIM2


Native DeltaV IO Data Definition - Using the Generic Device EtherNet/IP Scanner Driver, the VIM2 appears to the DeltaV controller as four Programmable Serial Interface Cards (PSICs).

Expanded Device Capacity - Using the DeltaV Serial card definition, a maximum of 128 devices can be configured per VIM2 (using one dataset per device).

Expanded Data Capacity - Each configured DeltaV Serial card dataset can support 100 16-bit registers.

Flexible Networking - User configurable IP addressing allows the VIM2 to be used in almost any plant environment regardless of networking scheme. The VIM2 TCP/IP configuration page allows the user to specify the VIM2 IP address, Subnet Mask, and Router address.

Simplex Only - Redundancy is not supported by the Generic Device EtherNet/IP Scanner VIM2 driver. The Rockwell PLC EtherNet/IP or the ODVA EtherNet/IP VIM2 drivers should be considered if redundancy is a requirement.

Easier, Intuitive Configuration - VIMNet Explorer has been developed to easily configure the VIM to integrate EtherNet/IP data into DeltaV. To support rapid implementation of EtherNet/IP projects, VIMNet supports the use of EDS files to get started with configuring connection definitions.


EtherNet/IP Messaging Supported


The Generic Device EtherNet/IP Scanner Driver for VIM2 supports the following Common Industrial Protocol (CIP) messages:

Implicit Class 1 Messages

Class1 connections are producer/consumer connections where both sides continuously send data at a predetermined rate. This is intended for connections to IO field devices. This type requires a TCP session to be established between devices, a forward open message then establishes the Class1 connection and data is subsequently sent via the UDP socket (2222). This includes both scanner connections (initiated by VIM2) to assembly instances in IO field devices or adapter connections accepted from Logix controllers (ENBT Adapter access). RPI is assigned in VIMNet for VIM2 initiated connections (i.e., where the VIM2 is the Scanner), or in the Logix configuration when VIM2 is the adapter. Both read and write buffers are updated to/from the field at these intervals; writes from DeltaV are by exception and trigger an immediate write to the field.

The message sent is prepended with a 16-bit sequence count value incremented only when the application updates the application production data.

Client Transport Meaning
Cyclic Message production is triggered by the Transmission Trigger Timer.
Change of State Message production is triggered when the application production data has changed and by the Transmission Trigger Timer.
Application Object Triggered Message production is triggered when the application updates the application production data and by the Transmission Trigger Timer.

Explicit Unconnected Messages (UCMM)

Unconnected messages use a TCP session and are intended as master/slave connections to send data to field devices under the control of the master. The VIM will be the master when using UCMM messaging. Writes are by exception, reads are continuous at the interval configured for the connection. The following are supported aspects of UCMM messaging:

  • DF1 - DF1 messaging uses embedded DF1 (PCCC) messages to read and write PLC5/SLC Mapped data in Rockwell PLCs.

Read/Write access to the following tag types is supported. Tag data type may be BOOL, SINT, INT, or REAL.

Explicit Class 3 Messages

Class 3 messages use a TCP connection to establish a link between sender and receiver, and then both sides send their data via the TCP session. These messages may be cached and un-cached. For cached, the connection is established and remains open until terminated. For un-cached, the connection is opened, the read/write message exchange occurs, and then the connection is closed. Messages formatting is of UCMM type as described above. Currently, these messages only support DF1 communications to DH+ via the Rockwell DHRIO module.

VIMNet Explorer

VIMNet Explorer is an intuitive Windows application used to setup Industrial Ethernet communication for DeltaV. This application is used for setup only and is not needed under normal operation of the VIM2. VIMNet Explorer can be installed on a DeltaV workstation or on a separate PC with a physical connection to the Industrial Ethernet network. The latest version of VIMNet Explorer is found under the software downloads page of www.mynah.com.

For the Generic Device EtherNet/IP Scanner Driver for VIM2, VIMNet Explorer allows the user to do the following.

  • Select the Network Interface Card (NIC) used for the Industrial Ethernet network.
  • Commission VIM2 modules (and older VIM2 modules) and assign them to DeltaV controllers.
  • Set network address, configure redundancy settings, and DeltaV Card definition for each VIM2.
  • Add EtherNet/IP devices, set data connections, and map data to DeltaV serial card registers.
  • Load and use EtherNet/IP Electronic Data Sheet (EDS) files for EtherNet/IP device configuration.
  • Create connection definitions to define how the VIM2 will communicate to the field devices.
  • Generate VIM2 configuration in FHX file format for importing into DeltaV Explorer.

VIM2 Product Description & Specifications


The VIM2 mounts on a 2-wide carrier on the left-hand-side of the DeltaV controller. A dedicated DeltaV power supply is required. The DeltaV Controller auto-senses a commissioned VIM2 as 4 DeltaV Programmable Serial Cards in slots 57-60 or 61-64.
