9.10.10 Making Printouts of Alarm and Diagnostic Data
The legacy CS300 controller firmware can create and print reports and events. The
Trusted™ system has no equivalent facility (and indeed has no printer output) but it
does have two event logs.
• The T8110 TMR processor maintains and holds an event log, which automatically
records all system faults and actions. This log includes module faults and swaps,
program downloads, and presses of the Reset button.
• The system also has a Sequence of Events log which records changes to Boolean
variables. This log includes timestamps (recorded to a precision of milliseconds),
but these are not absolutely accurate due to the disconnection between the
Trusted™ application and the CS300 I/O in the migrated system.
To make printouts of alarm and diagnostic data, open the appropriate log files in a
word processor or other text editor, and print them.
9.11 PREPARING FOR ENTRY INTO SERVICE
The application must be 100% tested against the functionality of the original
application before the migrated system is placed into service.
9.12 MAINTAINING THE MIGRATED SYSTEM
9.12.1 Maintenance Schedule
The requirements for the manual test intervals for the Trusted TM modules (including
the 8162 CS300 bridge module) are written in the Trusted TM PFD document 552762. In
addition, the following minimum requirements apply:
• The maintenance schedule for the migrated system must include a test of the
TM118-TWD watchdog module at least one time every year.
9.13 COMPLETION
After the migration is completed, return the ICCB modules and other unused CS300
parts to Rockwell Automation. Do not dispose of these items locally.
