Year 2000 Test Results
'Test results are complete on part of the "Schneider Automation" Family of Programmable Controllers.....
As a manufacturer of industrial electronic automation products, Schneider Automation has initiated an exhaustive, high priority test program to ensure that its systems will operate in an expected manner when the date changes at midnight, December 31, 1999.
Schneider Automation has been studying the affect of changes that may take place as a result of date change fields and related logic. Tests to assure that such changes will not incorrectly compute values or adversely impact system designs have been completed on part of the Schneider Automation family of products including the Modicon TSX Quantum. Testing on the remaining Modicon TSX line, the traditional Telemecanique line, and the SY/MAX line are still in progress but should be completed shortly. Test results for each unique implementation of the Real Time Clock function, the response, and the possible application effects are documented below.
Users must be aware that some "Modicon" products employ a "2" Digit NOT a "4" digit year field (i.e. 00 vs. 2000). Therefore, users should evaluate / understand their specific applications of the year field and insure that no "Subtract" or "Divide" functions are used that could negatively impact their process.
Test Criteria (Sample Test From attached):
Testing was conducted to insure that all Hardware and Software product date fields will "Rollover" correctly from:
December 31st, 1999 to January 1st, 2000 (both Powered and battery backed)! Each Months rollover verified! Leap year functionality tested (February 29th, 2000)! Set Date functions within the year 2000 and thru 2030! Power Cycles at rollover points! Illegal Set Date values!
Test Results:
Note: If the product is not listed below it does not employ a "Time of Day" clock and would not be subject to any problems with the Millennium (i.e. 184, 284, 384, 484, 584, etc.) ...
