PlcAppSystemInfo

Each PLC contains an instance of type 'PlcAppSystemInfo' with the name '_AppInfo'.

The corresponding namespace is 'TwinCAT_SystemInfoVarList'. This must be specified for use in a library, for example.

END_STRUCT
END_TYPE

ObjId

Object ID of the PLC project instance

TaskCnt

Number of tasks in the runtime system

OnlineChangeCnt

Number of online changes since the last complete download

Flags

Reserved

AdsPort

ADS port of the PLC application

BootDataLoaded

PERSISTENT variables: LOADED (without error)

OldBootData

PERSISTENT variables: INVALID (the back-up copy was loaded, since no valid file was present)

AppTimestamp

Time at which the PLC application was compiled

KeepOutputsOnBP

The flag can be set and prevents that the outputs are zeroed when a breakpoint is reached. In this case the task continues to run. Only the execution of the PLC code is interrupted.

ShutdownInProgress

This variable has the value TRUE if a shutdown of the TwinCAT system is in progress. Some parts of the TwinCAT system may already have been shut down.

LicensesPending

This variable has the value TRUE if not all licenses that are provided by license dongles have been validated yet.

BSODOccured

This variable has the value TRUE, if Windows is in a BSOD.

LoggedIn

This variable has the value TRUE if at least one XAE instance is logged into the project.

PersistentStatus

PERSISTENT variables: Restoration status:

PS_None: No persistent variables were restored.

PS_All: All variables that are persistent in the current project state were restored.

PS_Partial: Fewer variables were restored than are persistent in the current project state.

TComSrvPtr

Pointer to the TcCOM object server

AppName

Name generated by TwinCAT, which contains the port.

ProjectName

Name of the project

Differences compared with TwinCAT 2

If the variable runTimeNo was used under TwinCAT 2, the corresponding program code must be converted for application under TwinCAT 3.
