Ethernet/IP VIM2 v5.0.4 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 v5.0.4.

Product Description

These release notes are for the Ethernet/IP VIM2 firmware v5.0.4. Previous released driver is v5.0.2. The flash procedure is documented in the product manual.

Who Should Upgrade?

Recommended for all Ethernet/IP VIM2 applications.

Enhancements/Optimizations Implemented:

Added functionality to read/write L file types in MicroLogix and ControlLogix communications when using UCMM messaging. L File types comprise 32-bit integers. When configuring an L File type dataset, use Device Data Type = 11, Special Data 1 = 14, and Special Data 2 is the file number.

Defects Corrected:

This defect applies to sites using VIM redundancy and ControlLogix hot backup chassis. On chassis swap, a gratuitous ARP is sent to inform other devices about the new IP/MAC address. This ARP frame was being filtered out. Consequently, VIM communications with the currently active chassis did not resume for an extended time period.
