Virtual IO Module Hardware Installation

The Virtual IO Module (VIM) is installed exactly the same as a DeltaV Controller. Below are the procedures to install a simplex VIM and a redundant VIM.

Simplex VIM Hardware Installation

You will need two 2-wide carriers, 2 power supplies, one DeltaV controller and one VIM.

  1. Mount a power supply on the left side and the DeltaV controller on the right side of one 2-wide carrier. Mount a power supply on the left side and the VIM on the right side of the second 2-wide carrier. Connect the second 2-wide carrier to the left edge of the Controller 2-wide carrier. Repeat this step for all simplex VIM installations. The final assembly should be as shown in Figure 1.

  2. Connect a network cable from the VIM RJ45 port to a single isolated switch.

    Do not use the DeltaV Primary or Secondary switches for VIM field communications.

  3. Connect the PC with the VIMNet software to isolated switch connected to the VIM.

    The DeltaV ProPlus PC may be used to host the VIMNet Explorer so long as the DeltaV control network is not used for VIM communications.

Redundant VIM Hardware Installation

You will need three 2-wide carriers, 3 power supplies, one DeltaV controller and two VIMs.

  1. Mount a power supply on the left side and the DeltaV controller on the right side of one 2-wide carrier. Mount a power supply on the left side and the VIM on the right side of the other two 2-wide carriers. Connect the two 2-wide VIM carriers together and to the left edge of the Controller 2-wide carrier. Repeat this step for all redundant VIM installations. The final assembly should be as shown in Figure 2.

  2. Connect a network cable from each VIM Ethernet port to a separate dedicated isolated switch.

    Do not use the DeltaV Primary or Secondary switches for VIM field communications.

  3. Connect the PC with the VIMNet software to either one of the isolated switches connected to the VIMs.

    The DeltaV ProPlus PC may be used to host the VIMNet Explorer so long as the DeltaV control network is not used for VIM communications.

  4. Connect the two switches together with a network cable.

    This is required so that the VIMs can communicate with each other. Configuration and status information is passed between the VIMs using this connection. If this cable is not installed, VIMs will not be visible to each other and DeltaV Diagnostics will show a Standby unavailable error message.

  5. If the VIM-4201 VIM hardware is used, the redundancy link port must also be connected between the VIM’s.

    The redundancy link cable (supplied by Mynah) has RJ11 connectors on both ends. The VIM’s use this connection to send/receive redundancy coordination information. Please see Virtual IO Module Redundant Link for more information.
