The DeltaV Virtual I/O Module (VIM) provides an interface to plant Ethernet networks and devices that use the Modbus TCP/IP or Ethernet/IP protocols. DeltaV controllers can read and write signals from plant floor devices such as PLC's, Motor Control Centers, and Weigh Scales that are connected to these plant Ethernet networks.
The DeltaV system supports the S-series VIM and the M-series and S-series VIM 2. The S-series VIM operates with S-series controllers, the M-series VIM 2 is an upgraded model that operates with M-series controllers (MD Plus, MX, and MQ), and the S-series VIM 2 is an upgraded model that operates with S-series controllers (SD Plus, SX, SQ). The VIM has a single 10Base-T Ethernet network for field communications and a serial port for redundant VIM to VIM communications. The VIM 2 has two 10/100Base-T Ethernet networks. One network is for field communications and the other for redundant VIM to VIM communications.
The VIM represents the integration of the Mynah Technologies Virtual I/O Module (VIM) with the DeltaV system hardware. Each VIM is seen by the DeltaV controller as four DeltaV Serial Cards, allowing up to 128 serial datasets (with 100 registers per dataset) over 32 TCP/IP addresses and 128 Modbus addresses per VIM. Commissioned VIMs are auto-sensed by the DeltaV controller just as other DeltaV I/O Cards. I/O signals can be used in DeltaV Control Modules and displayed on DeltaV Operate graphics. Each DeltaV controller can have one redundant or two simplex VIMs.
Use the Mynah VIMNet Explorer to configure the plant Ethernet network. Graphical, drag-and-drop functionality makes setting up the plant Ethernet network quick and easy. VIMNet Explorer is integrated with DeltaV Explorer to make setup of the VIM easy and intuitive. With a DeltaV workstation connected to the plant Ethernet network, you can configure the VIM and the VIM interface to the plant Ethernet network and store the device configuration files in the DeltaV Version Control and Audit Trail database. Configure the devices from the PLC engineering workstation connected to the plant Ethernet network.
