This white paper discusses the use of Emerson VIM2 hardware with MYNAH Industrial Ethernet Drivers for successful third party device integration into DeltaV.
MYNAH Industrial Ethernet Drivers operating on DeltaV Virtual IO Modules 2 (VIM2s) provide a native DeltaV IO interface to Industrial Ethernet networks and devices implementing Modbus TCP/IP, EtherNet/IP, FMC722, or PROFINET protocols. With these protocols, DeltaV controllers can utilize high-speed Industrial Ethernet networks to communicate with plant floor devices such as programmable logic controllers (PLCs), motor control centers (MCCs), and weigh scales.
VIM2s using a MYNAH Industrial Ethernet Driver integrate natively into DeltaV by emulating IO cards in slots 57-60 or 61-64 in simplex configurations and as slots 57-64 in redundant configurations. The emulated cards can be Programmable Serial Interface Cards (PSICs), DeviceNet Cards, PROFIBUS Cards, or a combination of card types depending on the implemented MYNAH Industrial Ethernet Driver. Because DeltaV sees the VIM2 as native IO cards, signals from Industrial Ethernet Devices are configured and handled in the DeltaV Explorer for control logic in the same manner as other native IO. Additional details are available within the product bulletin for the DeltaV Virtual IO Module Network Gateway.
There are only a few hardware and software components involved, but integration of existing devices on Industrial Ethernet networks into DeltaV can be complex, as it requires expertise across all aspects of the system. Taking the time to properly understand the entire system has been proven to be a valuable effort for both new system integration and expansion of existing systems. While often overlooked, the integration of PLCs, MCCs, and other third party IO devices can take significant time during any one of the project phases. To reduce the time it takes to interface these devices into DeltaV, the best practices below simplify the integration of third party IO devices into DeltaV using the VIM2.
To successfully integrate a third party IO device, MYNAH has developed a recommended "best practice" system; the simplified integration is distributed across six distinct phases which allow for quick and seamless execution by efficiently allocating personnel focus and expertise.
The Discover phase of third party device integration is initiated by the customer's recognition of the need for field device integration with DeltaV in order to allow data exchange with PLCs, MCCs and other third party IO devices.
The detailed Design phase encompasses the investigation of the network architecture and system of devices. Typically, this phase will identify the interactions of the device(s) on a network as they relate to the VIM2 communications.
The primary goal of the Purchase phase is to provide the customer with the proper information necessary to make the most cost-effect decision by thoroughly explaining the capabilities of MYNAH's VIM2 drivers. This understanding allows the customer to be fully informed of the scope of hardware needed to operate the field devices and prevents the purchase of additional, unnecessary equipment.
The Support phase governs the process of initial communication with the field device. MYNAH can walk the customer through the following procedures via the MYNAH ticket system, MYNAH phone service, or as an on-site consultant. While this phase is an extension of the device integration, it does not include full device integration into DeltaV.
The Implement phase falls under the MYNAH Integration Services umbrella. In this phase, the full device(s) configuration is put in place and the network is tested. This is a critical phase of the project, as the documentation established during the detailed design review becomes a guide in understanding field device capabilities, ranging from transfer rates to redundancy testing.
The Train phase is the culmination of the five previous phases, and when completed as described below, can ease the maintainability of the components while simultaneously reducing the time required to expand the system in the future.
MYNAH's involvement in each of these six phases can be grouped into three separate services, each with a clearly defined scope and set of deliverables. These are described below:
MYNAH - VIM2 Driver Software Support
VIM2 Driver Software Support Service allows DeltaV users to continually maximize their financial return for a fraction of the cost of their initial investment. This service guarantees access to the latest revisions of MYNAH firmware and easily-available technical support, as required. Additional details are available within the VIM2 Driver Software Support Service webpage.
MYNAH - VIM2 Consulting Services
All aspects of Industrial Ethernet integration are taken into consideration by highly qualified MYNAH engineers, and the right individuals from across the company are brought together to create a complete and documented solution. In this way, MYNAH's Application Engineering and Product Development teams provide consulting services to assist DeltaV users with the successful implementation of Industrial Ethernet integration projects. The best results are achieved by following the proven six phase integration system as explained above, but with a heightened focus on the Design phase. When properly completed, the Design can be used to create the full implementation of the system with minimal consulting engagements required later in the downstream installation. For more information on services and deliverables, please refer to the Industrial Ethernet integration services webpage.
MYNAH - VIM2 Training
The Industrial Ethernet with DeltaV VIM2 training course helps students apply Industrial Ethernet expertise and strengthen their competencies in VIM2 Integration. Students begin with an introduction to the VIM and firmware options, moving through setup, tuning and configuring the various drivers. MYNAH Application Engineers instruct the course using real-world examples to help students to better use their VIM2 and successfully integrate it with various control systems.
The VIM2 product exposure course is offered at MYNAH Technologies in Chesterfield, MO, USA, but a custom course can easily be conducted on site, if the customer so desires. More information on MYNAH's training services is available on the Industrial Ethernet with DeltaV VIM2 Training webpage.
