This driver for the DeltaV VIM2 module 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 ODVA EtherNet/IP Driver, DeltaV Controllers can read and write signals from plant floor devices that support the EtherNet/IP, such as PLCs, Motor Control Centers, and Weigh Scales, using native DeltaV IO structures.
Native DeltaV IO Data Definition - Using the ODVA EtherNet/IP Driver, the VIM2 appears to the DeltaV controller as four Programmable Serial Interface Cards (PSICs) or four DeviceNet cards. Mixed configurations of both Serial and DeviceNet cards totaling four cards are supported in Simplex configurations. In Redundant configurations, the VIM2 appears as 4 PSICs only.
Expanded Device Capacity - Using the DeltaV DeviceNet card definition, a maximum of 244 DeviceNet devices can be configured per VIM2 under 128 field devices or IP addresses. Using the DeltaV PSIC definition, a maximum of 128 field devices or IP addresses can be configured per VIM2 (using one dataset per device).
Expanded Data Capacity - Each configured DeltaV PSIC dataset can support 100 16-bit registers. Each configured DeltaV DeviceNet card definition can support 255 signals.
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.
1:1 Module Redundancy - Redundancy can be added to any system by adding a second VIM2 and configuring the two modules as a redundant pair. In redundant configurations, the VIM2 appears as 4 Redundant DeltaV PSIC pairs. DeviceNet card definition is not supported in redundant installations. Automatic switchover of primary to standby cards is handled like the DeltaV Serial Card. The operator is given clear notification of a switchover at the operator display. Manual switchover can be controlled in DeltaV Diagnostics.
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 Explorer supports Logix5000 L5X files and on-line direct EtherNet/IP data browsing, as well as EDS file uploads. VIM2 configuration can be exported from VIMNet Explorer as a DeltaV FHX file supporting quick setup in DeltaV.
The ODVA EtherNet/IP Driver for VIM2 supports the following Common Industrial Protocol (CIP) 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.
|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.|
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 VIM2 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:
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 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 with a physical connection to the Industrial Ethernet network, or on a separate PC. The latest version of VIMNet Explorer is found under the software downloads page of www.mynah.com.
For the ODVA EtherNet/IP Driver for VIM2, VIMNet Explorer allows the user to do the following.
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 or DeviceNet Cards in slots 57-60 or 61-64.
