Tag Write Issue

I am running the Module Allen-Bradley Drivers 1.4.0 (b196) on Ignition 7.4.1 communicating with an AB CompactLogix via Ethernet. Gateway is running on Server 2008R2.

We clearly have a situation where a system.tag.write() is not executing properly (the value does not get written to the PLC). I am wondering if I should simply update the Allen-Bradley drivers version.

We cannot simply upgrade Ignition since it is a validated system. We can, however, upgrade the ethernet driver if needed. If so, what driver should I be upgrading to if I am only using 7.4.1?

Below is the wrapper.log contents from the time of the issue. Thanks
