0 Temperature threshold 1 exceeded
1 Temperature threshold 2 exceeded
2 Incorrect temperature value
BYTE
Remaining Global Force
Duration [ms]
Time in ms until the time limit set for global forcing expires. DINT
CPU Watchdog Time [ms] Maximum permissible duration of a cycle in ms. UDINT
Cycle Time, last [ms] Current cycle time in ms UDINT
Cycle Time, max [ms] Maximum cycle time in ms UDINT
Cycle Time, min [ms] Minimum cycle time in ms UDINT
Cycle Time, average [ms] Average cycle time in ms UDINT
Table 18: Hardware System Variables for Reading the Parameters
The following system variables taking from
Table 18 are arrays. Their index is the
processor module number:
OS Major, OS Minor
Redundancy Info (bit bar)
Power Supply State
Temperature State
The processor module index used in these fields is mapped onto the slots of the processor
modules in the base plates as specified below:
1. In base plate 0, the index is counted in ascending order starting with slot 3.
2. In base plate 1, the index is counted in descending order down to slot 3.
The following assignment results:
Slots
3 4 5 6
Rack 1 4 3
Rack 0 1 2 3 4
Table 19: Assigning the Index to Processor Module Slots
Processor modules with indexes 3 and 4 can either be located in rack 0 or rack 1!
