ESM System Variables

System Variable Data Type Description
ESM_DATA ESM_DAT ESM Data structure

ESM_COUNT
USINT Number of ESMs (one ESM per processor core)

ESM_INFOS
ESM_INFO_ARRAY Information on ESM [1...2]


[1]..[2]



TASK_COUNT
UINT Number of tasks that have been configured for the ESM



TICK_COUNT
UDINT Always 0



TICK_INTERVAL
UDINT Always 0



TASK_INFOS
TASK_INFO_ARRAY Information on task [1...16]




[1]...[16]






INTERVAL
LINT For cyclic tasks: time interval in μs





PRIORITY
INT Priority of task





WATCHDOG
LINT Watchdog time in μs; no watchdog: 0. The watchdog time will be defined for the sum of execution duration and delay time. If the watchdog time is exceeded the watchdog will trigger.





LAST_EXEC_DURATION
LINT Execution duration of the task in the previous cycle in μs (including interruptions by higher priority tasks)





MIN_EXEC_DURATION
LINT Minimum execution duration of the task in μs (including interruptions by higher priority tasks)





MAX_EXEC_DURATION
LINT Maximum execution duration of the task in μs (including interruptions by higher priority tasks)





LAST_ACTIVATION_DELAY
LINT Delay time of the task in the previous cycle in μs (delay occurs if higher priority tasks are pending at the time of task activation)





MIN_ACTIVATION_DELAY
LINT Minimum delay time of the task in μs (delay occurs if higher priority tasks are pending at the time of task activation)





MAX_ACTIVATION_DELAY
LINT Maximum delay time of the task in μs (delay occurs if higher priority tasks are pending at the time of task activation)





EXEC_TIME_THRESHOLD
LINT Threshold value that you can define for the sum of execution duration and delay time





EXEC_TIME_THRESHOLD_CNT
UDINT If the defined EXEC_TIME_THRESHOLD value is exceeded, the value of the EXEC_TIME_THRESHOLD_CNT variable is incremented





NAME
STRING Task name

EXCEPTION_COUNT
USINT Number of exceptions

EXCEPTION_INFOS
ESM_EXCEPTION_INFO_ARRAY Information on exceptions [1...2]


[1]...[2]




TYPE_ID
UDINT

ID of the exception

0 = None

1 = ARP exception (see details in SUB_TYPE and SUB_TYPE_ID)

2 = STD exception (see details in SUB_TYPE)

3 = Unknown exception

4 = Signal

5 = Task WatchDog




SUB_TYPE
STRING512 Subtype of the exception (for example, std::exception, Arp::System::Commons::ArgumentException)



SUB_TYPE_ID
UDINT

Provides detailed information for ARP exceptions (if TYPE_ID = 1)0x4000 = PLC exception

0x4001 = PLC division by zero exception

0x4002 = PLC index out of range exception

0x4003 = PLC stack overflow exception

0x4004 = PLC string error exception




TASK_NAME
STRING Name of the task in which the exception occurred



PROGRAM_NAME
STRING512 Name of the program instance in which the exception occurred



INFORMATION
STRING512 Information on the exception that occurred
