46
Qualification status. The reason code for why the processor failed
qualification or if the configuration parameters were changed by the
primary. Valid values include:
0 - Passed qualification
1 - Equivalence check - Ladder programs different
2 - Equivalence check - Data table structures different
3 - Equivalence check - I/O map tables different
4 - Equivalence check - ControlNet Backup Configuration and Status files
different
5 - Equivalence check - Force tables different
6 - Equivalence check - Status files different
7 - Qualification passed, but configuration parameters changed by
primary
8 - Qualification failed due to processor being faulted
9 - Qualification failed due to keyswitch change to Program mode
10 - Qualification failed due to Run mode inhibited
11 - Qualification failed due to processor uploading or downloading
program
12 - Qualification failed due to ContronNet reconfiguration in progress
13 - Qualification failed due to invalid backup state
14 - Qualification failed due to partner no longer being a primary
15 - Qualification failed due to invalid backup configuration parameters
16 - unused
17 - Qualification crossload failed
18 - Qualification failed due to unavailable edit resource
47
Lost Partner Counter. A counter which increments every time you lose
communication with the partner processor.
48
Maximum Program Scan Exceed Counter. A counter which increments
every time the maximum program scan time is exceeded. This counter is
reset for the processor on transition into Run mode.
49
Equivalence Check Error. A bit is set for each area in which an
equivalence mismatch is detected. There is a background check of the
ladder program, force tables, and status files for differences.
Bit 0 - Set if the ladder programs between the two systems are different
Bit 1 - Set if the data table structures between the two systems are
different. Note the data table structure is not the same as the values in
the data table files.
Bit 2 - Set if the I/O map tables between the two systems are different
Bit 3 - Set if the Backup Configuration and Status files between the two
systems are different
Bit 4 - Set if the Force tables between the two systems are different
Bit 5 - Set if the Status files between the two systems are different
50
Qualification Crossload Time. The time (in ms) it takes to crossload the
entire data table from the primary processor to the secondary processor.
This value is overwritten each time the processor goes through
qualification.
51
On-Demand Crossload Time. The time (in ms) it takes to crossload the
data table state information from the primary to the secondary. This
value is overwritten each time the processor goes through qualification,
and when you initiate an On-Demand Data Table Crossload command.
52
Crossload Active. This word equals 1 when a crossload is active; it is
equal to 0 when a crossload is not active. This word applies to both
Qualification and On-Demand crossloads.
