Specification	Description
Title: `Mode` Code: `mode` Visibility: `no` Default: `Asynchronous startup`	Waiting mode for OS process termination. Possible values: `Asynchronous startup` (`async`, `0`) - Immediately after the process starts, passes control to the next component. `Waiting for completion` (`sync`, `1`) - Passes control to the next component only after the process completes or a wait timeout.
Title: `Path to executable file` Code: `path` Visibility: `no` Default: —	File path or OS command. Command line prefix. The prefix must be resolved in the file permissions.json. Examples of specifying commands: `echo` `myprogram1` `/bin/myprogram2` `:GLOBALSHARE_COMMON/cmd/myprogram3` `bash :SYNC_COMMON/cmd/myscript.sh` To resolve these examples, the 'permissions.json' file must have the following content: { "exec_perm": { "check": true, "user": "root", "commands": [ "echo", "myprogram1", "/bin/myprogram2", ":GLOBALSHARE/common/cmd/myprogram3", ":SYNC/common/cmd/myscript.sh" ] } } Using bash scripts you can run any commands, permission is only checked on the path to the starting bash script.
Title: `Command Line Startup Parameters` Code: `params` Visibility: `no` Default: —	Command postfix containing parameters.
Title: `Time, s` Code: `timeout` Visibility: `yes` Default: —	Waiting timeout for the process to complete.
Title: `Transition` Code: `transfer` Visibility: `no` Default: —	A component to which control is passed after an asynchronous startup, or after a successful completion of a process.
Title: `Result to variable` Code: `result` Visibility: `no` Default: —	Variable to save the console output of a completed process.
Title: `Transition, Error` Code: `transferError` Visibility: `no` Default: —	Component to which control is passed in case of a startup error or process crash.
Title: `Reason for error to variable` Code: `error` Visibility: `no` Default: —	Variable to save the error.
Title: `Transition, Time` Code: `transferTimeout` Visibility: `yes` Default: —	The component to which control is passed after the process completion wait time has elapsed.
