Ethernet/IP VIM2 v5.0.1 Release Notes
By Nobin William
Product: IOD-4112 - Rockwell PLC EtherNet/IP Driver for DeltaV VIM2

These release notes are for the Ethernet/IP VIM firmware for v5.0.1.

Product Description

These release notes are for the Ethernet/IP VIM2 firmware v5.0.1. Previous released driver is v5.0.0. The flash procedure is documented in the product manual.

Who should upgrade?

Mandatory for all Ethernet/IP VIM2 applications.

The following enhancements were implemented:

1. The communications between the DeltaV Controller and VIM2 have been optimized. Each emulated serial card now communicates with the Controller independently and in parallel. This improves throughput.

The following defects were corrected:

1. On power-up without a network connection, the VIM2 would disable its network internally and become completely unavailable. This defect has been corrected. After power-up, the VIM2 now periodically checks if the network link is available and resets itself for communications.

2. The VIM2 internally buffers incoming field data prior to transmission to the DeltaV Controller. However, when connected to field devices with high volume of continuously changing data values, the VIM2 buffers would get depleted, causing buffer resets and loss of Controller/VIM2 Railbus communications. This defect has been corrected.
