You are here: VIMNet Explorer > VIM Placeholder

VIM Placeholder

This represents the Virtual IO Module. The context menu options for the placeholder are described below. Menu items have similar behavior when comparing simplex and redundant VIMs. If the operation can only be performed on one VIM (i.e., commission and decommission), then there is a sub-menu allowing you to pick the VIM for the operation.

Upload Configuration to VIM

This option will compile the current configuration and transmit it to the VIM. If the VIM placeholder is redundant, there will be options to upload each VIM independently, or upload both of them at the same time.

In a redundant VIM configuration, if one VIM is uploaded, it will stop communications with the field devices. The other VIM in the pair will still communicate with the field. This feature can be used to send a new configuration to the field without completely interrupting communications. During the upload the VIM that is receiving the configuration will show a bad status in DeltaV Diagnostics.

This operation will interrupt ALL field communications through the selected VIM.

A guide for uploading the VIM can be found here: Upload Virtual IO Module Configuration.


This option will assign the selected VIM to the VIM Placeholder. When this is selected the dialog in Figure 3 will appear.

Figure 3 - VIM Commissioning Dialog

If required, the VIM identify command (Start Flashing) can blink the lights on the VIM.

When commissioning redundant VIMs, each VIM must be commissioned independently. A redundant VIM appears in DeltaV as four redundant serial cards. One VIM (VIM A) is responsible for all of the odd-numbered serial cards, while the other (VIM B) is responsible for the even-numbered cards.

A guide for commissioning the VIM can be found here: Commission a Simplex Virtual IO Module.


This option will remove the configuration from the VIM and return it to the decommission list. DeltaV Diagnostics will show the VIM's serial cards as "CfgButNotPresent" if the VIM is configured in DeltaV but not commissioned.

This operation will stop ALL field communications through the selected VIM.


This will delete the selected placeholder and all objects contained within. If the placeholder is commissioned, the delete command will send the decommission command to the VIM and then delete the placeholder.

This operation will stop ALL field communications through the selected VIM.


This menu option will launch the VIMNet Diagnostics application. This application shows the status of the VIMs defined in the VIO configuration file of VIMNet Explorer.


This will open the properties dialog of the VIM placeholder.

Figure 5 - Redundant VIM Configuration Dialog

This defines basic properties of the VIM. These items can only be changed on VIM placeholders that are not commissioned. The meaning of the properties in the VIM placeholder dialog (Figure 4 and Figure 5) are identical between simplex and redundant; the only difference is that the redundant dialog allows you to specify a Name, IP Address, Subnet Mask, and Gateway for two VIMs instead of just one. Each property is defined below.

Reconcile VIM

This option is used to bring a VIM from the Decommissioned list that is in the state Commissioned - Unknown and assign it to the selected VIM placeholder. During the reconcile process, the VIM will not be disturbed; any field communications will not be interrupted. The reconcile process will only assign a commissioned VIM to a placeholder with a matching name and IP address.
