Subject: Connecting to a Controller or Emulator in TriStation 1131 v4.6.x May Corrupt an Application

Affected Products

TriStation™ 1131 Developer's Workbench Software version 4.6.x

Problem Description

Connecting TriStation 1131 v4.6.x to a controller or the Emulator may corrupt the project's Current Version value, resulting in a project that cannot be safely upgraded to TriStation 1131 v4.7.x or later.

Background

Connecting TriStation 1131 v4.6.x to a controller or the Emulator may corrupt the project's Current Version value. A project with a corrupted Current Version value cannot be safely upgraded to subsequent releases of the TriStation 1131 software. Performing a Download Changes operation after upgrading the project from TriStation 1131 v4.6.x to v4 .7.x or later may result in unpredictable control program behavior.

Operational Restrictions and Recommended Actions

The issue described in the Problem Description section only applies to TriStation 1131 v4.6.x . Other versions of the TriStation 1131 software do not exhibit this problem.

To ensure that your project's Current Version value is correct, follow the procedure appropriate to your situation:

Note: All Download Changes and Download All operations described in this section are to the controller.

• If your project was last opened in TriStation 1131 v4.6.x, you need to upgrade the project to TriStation 1131 4.7.x or later:
