These release notes are for Ethernet/IP VIM Firmware v3.4.1.

The previous general released firmware version is v3.3.64. The flash procedure is documented in the product manual.

Upgrade to this release is MANDATORY for all uses of the Ethernet/IP VIM with firmware at or prior to v3.3.64.

New Features

• Support for DeltaV v11.3 using the Virtual IO Module or Emerson Ethernet IO Card.  VIMNet Explorer v9.1.2.23 or later must be used when configuring this driver for use with DeltaV v11.3.

Corrected Issues

1. After VIM reboot, dataset register value initialization write requests from the DeltaV Controller were discarded until the VIM was fully online. Unless the DeltaV Controller continued to send writes to the VIM, the datasets remained at their original static values. This defect has been corrected.

2. When deploying VIM’s in redundant mode and using Dual ENBT card redundancy, a defect was found when the configuration contained a single Output only dataset. Such a configuration had a low level conflict between dataset output messages generated by DeltaV Controller writes, and Ping messages generated by the VIM. This conflict caused all output messages to stop working. This defect has been corrected.
