Note: The MYNAH Virtual I/O Module (VIM) is discontinued/maintained as of January 2014. No new units will be sold and technical support will be limited. The Emerson Virtual I/O Module 2 is the official replacement of the VIM.
The Virtual IO Module (VIM) Network Gateway provides a native DeltaV IO interface to Industrial Ethernet networks and devices that use the Modbus TCP/IP, EtherNet/IP, or the FMC722 protocol.
Using the VIM, DeltaV Controllers can read and write signals from plant floor devices connected to Industrial Ethernet networks such as PLCs, Motor Control Centers, and Weigh Scales.
Seamless DeltaV Integration - Each Virtual IO Module is seen by the DeltaV Controller as up to 4 Virtual DeltaV Serial Cards. Commissioned Virtual IO Modules are auto-sensed by the DeltaV controller as DeltaV Serial Card(s)
Configured in DeltaV Explorer - Dataset configuration is done in the DeltaV Explorer in the same manner as a DeltaV Serial Card. IO signals can be used in DeltaV Control Modules and displayed on DeltaV Operate graphics.
Intuitive Setup - The VIMNet Explorer Utility makes setup of the Virtual IO Module easy and intuitive. Graphical, drag-and-drop functionality makes setting up the plant Ethernet network quick and easy.
Powerful Integration Solution - Each Virtual IO Module can emulate up to 4 DeltaV Serial Cards and support up to 128 Serial Card Datasets of information. Communication over the plant Ethernet network is fast and efficient.
Flexible Networking - User configurable IP addressing allows the Virtual IO Module to be used in almost any plant environment regardless of networking scheme. The Virtual IO Modules and the plant Ethernet devices must be on the same IP subnet to communicate.
1:1 Module Redundancy - Redundancy can be added to any system by adding a second Virtual IO Module and configuring the two modules as a redundant pair. The Virtual IO Module appears as up to 4 Redundant DeltaV Serial Card pairs. 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.
Modular Rugged Package - The DeltaV Virtual IO Module mounts in the same manner as the DeltaV controller. It mounts in the controller slot of a DeltaV 2-wide horizontal or 4-wide vertical carrier and uses a standard DeltaV Power Supply. The advanced design of the DeltaV Virtual IO Module will provide years of uninterrupted use.
The Virtual I/O Module 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 Virtual IO Module as 4 DeltaV Serial Cards.
Configuration of the IO signals from the commissioned Virtual IO Module is done in the DeltaV Explorer in the same manner as a DeltaV Serial card.
VIMNet Utility - The VIMNET Utility allows the user to commission the Virtual I/O Module, setup primary and redundant Virtual I/O Modules, and the Industrial Ethernet Network. The user is able to specify the IP address, Subnet Mask, and Gateway of each Virtual IO Module and set the node address and names of each Plant Ethernet Network device that is used by the Virtual IO Module. The VIMNET Utility runs on the MS Windows XP or Windows 7 operating system and has an intuitive, graphical user interface. Connection to the Virtual IO Module is done through the Module RJ-45 Ethernet Connection.
Module Redundancy - Two Virtual IO Modules can be set up as a redundant pair for installation that require backup plant networks. Each Virtual IO Module will be installed on its own 2-wide carrier, with its own power supply to the left of the DeltaV Controller.
The active and standby Virtual IO Modules monitor each other with a continuous status command using the redundancy link cable supplied with each redundant pair. The active Virtual I/O Module communicates over the network to the Industrial Ethernet device and the standby sends an intermittent signal to the device to maintain communication integrity.

Modbus TCP/IP - The Virtual I/O Module with the Modbus TCP/IP Master Driver supports the following Modbus communications protocol function codes to read and write values to and from a Modbus slave device, as specified by the Modbus Application Protocol Specification from Modbus-IDA.org.
The Virtual I/O Module Modbus TCP/IP Driver supports the following Modbus function codes:
The VIM can function as both a Modbus TCP/IP master and slave simultaneously. Master or slave mode is set at the virtual port level. In master-only mode, this driver can communicate with a maximum of 32 slave devices. Systems that use both master and slave mode can communicate with a maximum of 16 slaves and 16 masters at the same time. The master and slave capability is available in simplex implementations only. In redundant applications, only master mode is supported.
EtherNet/IP - The Virtual I/O Module with the EtherNet/IP Scanner Driver provides the following compatible functions using the Control and Information Protocol (CIP) as defined in the EtherNet/IP Specification from Open DeviceNet Vendor Association & ControlNet International.
Systems using either mode can communicate with a maximum of 16 devices at the same time.
The Virtual IO Module Ethernet/IP Scanner Class Driver provides:
FMC722 Ethernet Protocol -
The VIM FMC scanner is an online process in the VIM. It is designed to run continuously; updates to the configuration are by uploads from the VimNet Explorer and downloads from DeltaV controller. Once installed, commissioned and uploaded, the VIM FMC scanner automatically opens its connection to the TPU when DeltaV downloads the card configuration (all four cards in DeltaV). The IO Point definitions are configured into the VIM scan table the DeltaV configuration is loaded.
On VIM restart (following power loss), the Configuration is read from EPROM in the VIM and the communications is automatically restored.
Each sensor/actuator IO point is an object and consists of multiple parameters; each parameter is a separate DeltaV register. As each parameter value may of a different data type, the registers for an individual IO point will be mapped to separate dataset/register combinations. A register in a separate dataset will be assign for each parameter required for a point. This means there will be one dataset for each point value and the register in each dataset corresponds to the tag index (under the device, not TPU).
There will be a maximum number of tags in a single VIM. This number will limit the number of SPCU’s that may be connected to the VIM. The more tags in an individual SPCU, the fewer SPCU’s. Based on how the tags are entered into the datasets under a device, there will be further limits on the total tags (as some datasets may not be fully utilized). Note also that 32-bit datasets (integer and floating point) in DeltaV only allow 50 registers while discrete, 8 and 16-bit datasets allow 100.
The DeltaV Virtual I/O Module (VIM) provides a native DeltaV I/O interface to open plant Ethernet networks and devices that use FMC722 (TCP) protocol. DeltaV controllers can read and write signals from the connected TPUs. As such, the VIM is a Network Gateway between DeltaV controllers and field subsea devices supporting network communications.
