This article walks through the workflow of using the DeltaV Virtual IO Module (VIM) starting with registering for an account at MYNAH.com to creating DeltaV datasets.
Every instance of the VIM has an associated Site ID. This is a unique number that allows MYNAH to track, maintain, and support each unique licensed instance of the VIM firmware. This is NOT the same number as, nor is there any direct correlation to, the DeltaV System ID. Every time a copy of any VIM firmware is purchased, the Site ID is emailed with the Order Confirmation to all listed parties on the PO. VIM firmware Site IDs are allocated per purchase order and per type. For example:
A Site ID will be required to download associated files and receive support. The Site ID can be found in the confirmation email sent to all listed parties on the PO. If the confirmation email cannot be found, register for an account at MYNAH.com, open a support ticket requesting the Site ID, and provide the following information:
MYNAH recommends that every person who requires access to downloads and technical support register for a unique user account at MYNAH.com. End customers, Emerson Local Business Partners and integrators may all register for an account, open support tickets, and access downloads associated with a Site ID. To access the registration form, go to http://www.mynah.com, click "MENU," expand Client Login under Resources, and click "Register." New users will have the opportunity to specify Site IDs when registering. Access to the downloads for the Site ID will be granted if the Site ID is provided at registration.
The application for registration will be reviewed by MYNAH staff during normal business hours. The approval process will typically only take a few minutes. Applications submitted after business hours will be reviewed on the next business day. A confirmation email with instructions for logging in will be sent once the account has been approved.
If the Site ID was not specified at the time of registration or the firmware was purchased after registration, Site IDs can still be applied to the user account. Simply open a support ticket and request to add the Site ID to your account.
For more details about an account at MYNAH.com and how to open a support ticket, see the following link: My Account at mynah.com Features and Directions
The latest versions of the VIM firmware and VIMNet Explorer downloads can be found on the Site ID page that can only be accessed by users that have successfully linked their accounts to the Site ID. To access the Site ID page, log onto your account, click "MENU" at the top-left, and click the "Software Licenses" button. The Software Licenses page will list all of the Site IDs associated with the user account, including overview details about the site such as: the Company Name, Product Family, and Support Expiration. Click the Site ID to access the Site ID page. Note: Any number of users may be attached to and access the Site ID page.
Notice the Support Expiration section. Downloads will not be available for this Site ID if support has expired. Annual support will need to be purchased through the Emerson Local Business Partner to continue access to downloads and technical support.
If support is not expired, attached users can download any of the files listed in the Site ID's Downloads section by following the links. The following files will be available:
Download these files to the computer which will run VIMNet Explorer.
The following items are requirements for VIMNet Explorer:
If these requirements are not met, MYNAH cannot guarantee complete and proper functionality of VIMNet Explorer. Anti-virus software, the Windows Firewall, and the lack of Administrative privileges on the computer can all prevent VIMNet Explorer from properly accessing the computer's network card, resulting in failures that include but are not limited to:
If any of these failures are encountered, check that the requirements have been met. These failures very rarely occur when the above requirements have been met. If any of these failures is encountered after ensuring that the above requirements are met, please contact MYNAH Technical support.
After the files have been downloaded from the Site ID page, extract all of the .zip files. Run the VIMNet Explorer installer and follow the installer's instructions.
Once installed, locate VIMNet Explorer under the Windows Start Menu, right-click the icon, and select "Run As Administrator." This step is necessary even if logged into the Windows machine as an administrator. If VIMNet Explorer is launched without Administrator privileges, it will open but VIM operations over the network, such as commissioning and flashing, may fail.
If prompted to select a network card (NIC) when VIMNet Explorer is initially launched, select the IP Address of the computer from the "Available NIC" selection and click the "Add" button. The IP Address of the NIC that is connected to the VIM/PLC network must be used. Only the correct IP Address should be listed in the Used Addresses field. If there are multiple IP Addresses listed there, select and delete all IP address that are not connected to the VIM/PLC network. Once the PC IP address on the VIM/PLC network is the only IP in the list, click "OK" to continue to VIMNet Explorer.
Verify that the network settings are correct. Right-click "Physical Network" in the tree on the left side of the VIMNet Explorer window and select "Properties." Again, make sure that only the correct IP Address is listed under the Used IP Address. Delete any other IP Addresses from the list.
All new VIM2 hardware shipped to customers will be pre-loaded with Simulation firmware. This firmware is designed for process simulation use with Mimic Simulation Software and the Mimic Railbus SIO Driver. Simulation Firmware is not a valid Industrial Ethernet Gateway firmware. The VIM must be commissioned and flashed to the desired firmware before it can be used as a gateway VIM. A VIM cannot be commissioned to a placeholder in VIMNet Explorer that does not match the firmware type currently loaded on the VIM. In VIMNet Explorer, there are two classes of VIM placeholders; Simulation VIM placeholders, and I/O Net VIM placeholders. Because new VIM hardware shipped from Emerson comes with Simulation Firmware, they must be commissioned to a Simulation VIM placeholder to be flashed to the appropriate Gateway IO Driver for use in a real process.
To get started, click the Decommissioned VIMs list to see the list of available VIMs on the network. If any of the VIMs are missing from the list, right-click "Decommissioned VIMs" and select "Refresh." Refreshing the list sends a special beacon on the network and all VIMs are designed to respond to this message. VIMNet Explorer will populated the decommissioned VIMs list based on the responses that are received. If no VIMs are listed, VIMNet Explorer was either not able to send the command or no responses were received.
If no VIMs are listed under the Decommissioned VIMs list, verify the following:
Once all of the VIMs are available in the Decommissioned VIMs list, create a VIM placeholder under "Simulation Net." Right-click the Simulation Net and select "New Simulation VIM." Provide a valid and available IP Address and a valid subnet mask for the VIM. Use the Ping button to verify that no other device on the network has this IP Address. Click "OK" when done.
Right-click the Simulation VIM placeholder and select "Commission." All Simulation VIMs should be listed as available for commissioning. VIMs with different firmware types will not be listed. Select the VIM to commission and click "OK." Once the VIM has been commissioned, the IP Address at the placeholder will be applied to the VIM. Use the VIMNet Explorer computer to ping the VIM's IP Address to verify that the VIM is correctly responding on the network.
At this point, the VIM should have Simulation firmware flashed and be commissioned with a valid IP Address. The VIM must be flashed to a different firmware to act as an Industrial Ethernet Gateway. At least two .hex files should have been included in the files downloaded from the Site ID page: a Simulation firmware .hex file and an Industrial Ethernet Gateway .hex file. For VIM2 hardware that is currently flashed with Simulation firmware version 2.5.3 or below, a flash to latest Simulation firmware is required. Once the VIM is flashed to the latest Simulation firmware, the VIM can be flashed using the Industrial Ethernet Gateway .hex file downloaded from the Site ID page.
In VIMNet Explorer, right-click the Simulation VIM placeholder again and select "Properties." Click the "Flash Upgrade" button, browse to and select the .hex file, and click "OK." This will start the flash process and it may take several minutes to complete. If the flash fails for any reason, check the following:
If the VIM firmware type was not changed during the flash upgrade, as would be the case when flash upgrading from an older version of Simulation firmware to the latest, the VIM will remain commissioned. After this initial VIM flash to the latest version of Simulation firmware is complete, the instructions above should be repeated to flash upgrade the VIM to the Industrial Ethernet Gateway firmware.
If the VIM firmware type was changed during the flash upgrade, the VIM should be automatically decommissioned because a VIM cannot be commissioned to a placeholder that does not match its firmware type. Sometimes it may take a moment for VIMNet Explorer to show that the VIM has been decommissioned. If the icon is not updating, press the F5 key to update the display. The VIM should also be listed under the Decommissioned VIMs list with the updated firmware version that matches the version listed in the name of the .hex file. This VIM is now ready to be commissioned to an I/O VIM placeholder.
An I/O VIM placeholder must now be created, similar to how a Simulation VIM placeholder was created when the VIM was flashed with Simulation firmware. Right-click I/O Net and select "New Controller." Provide a name for the controller to match the name of the controller in DeltaV. Right-click the controller and select "New IO VIM." A new configuration window will appear. Perform the following:
Click "OK" to finish once the VIM placeholder has been configured.
Right-click the newly created I/O VIM Placeholder and select "Commission." Your VIM should appear in the list of available VIMs. Select the VIM and click "OK." Click "OK." to confirm the commission. Verify that the VIM has been properly commissioned by using the VIMNet Explorer computer to ping the VIM.
If the VIM does not appear in the list of available VIMs, check the following:
The next step is to add devices in VIMNet Explorer that correspond to the devices in DeltaV. If a device is configured in DeltaV under Card 57, Port 1, then a device must be added in VIMNet Explorer under Card 57, Port 1. Make sure to create a device in VIMNet Explorer for every device in DeltaV regardless of which firmware is flashed to the VIM.
To add a device, expand the VIM, expand one of the cards, right-click the Port, and select "Add Device." A new windows will pop up for defining the device. Change the Device Address to match the device address in DeltaV Explorer. Click the "Add" button and specify the IP Address of the device and click "OK." Click "OK" again to finish the device configuration.
If using the IOD-4101/4111 or IOD-4102/4112 firmwares, no additional configuration for the device is required. If using IOD-4104/4114 or IOD-4116, at least one connection definition must be created and assigned to the device. The connection definition defines the communication details. When IOD-4101/4111 or IOD-4102/4112 are used, the communication details are defined by the dataset configuration in DeltaV.
The I/O VIM Configuration will be complete once all of the devices have been added (with connection definitions if necessary).
Once the configuration is finished, right-click the VIM and select "Upload Configuration to VIM." There is an option to upload the configuration to VIM A, VIM B, or Both if this is a redundant VIM pair. The configuration will need to be uploaded to both VIMs, either individually or all at once. The VIM's serial cards should be visible to the controller across the railbus after uploading the configuration to the VIM.
The VIM should emulate the DeltaV serial cards after the configuration has been uploaded. The VIM cards can be added to DeltaV automatically or manually. To automatically add the VIM's cards to DeltaV and verify that the VIM is emulating the cards in one step, right-click <Controller> -> I/O and select "Auto-sense I/O Cards." The VIM's configured cards (57- 60 or 61-64) should be auto-sensed by the controller and added to the controller's I/O automatically. Next, download all four cards. After the download, right-click the controller and select "Diagnose" to open DeltaV Diagnostics. Verify that the Serial Cards do not show "Configured but not Present" errors. The VIM is properly emulating the serial cards if there are no errors at this point.
If the cards are added manually, then the emulation will need to be verified through DeltaV Diagnostics. To add the cards manually, right-click lt;Controller> -> I/O and select "New Card." Select the following settings for the card:
All four of the VIM's cards must be added then downloaded. Once the cards have been downloaded, right-click the controller and select "Diagnose" to open DeltaV Diagnostics. Verify that the Serial Cards do not show "Configured but not Present" errors. The VIM is properly emulating the serial cards if there are no errors at this point.
Instructions for configuring DeltaV datasets for the Rockwell PLC EtherNet/IP driver and Modbus TCP/IP driver can be found in the VIMNet Explorer Help files:
The DeltaV dataset configuration for the Generic EtherNet/IP and ODVA EtherNet/IP drives is defined by the connection definition. In VIMNet Explorer, browse down to "Device→Connection Definition→Dataset." Click on the dataset. The DeltaV dataset configuration for this connection definition will be listed on the right-hand side. Copy the configuration exactly to the dataset in DeltaV.
