Complex preprocessing and complete generation-imitation of the SMART fields with separate attributes on the internal programming language of OpenSCADA into the configuration IO inProc (with appending the builtin syntax highlight rules), where you can operate next service parameters:
- alLev, tErr [IN|OUT] — alarm level [-79...0] and text of the error (the attribute "err" format);
- f_frq [IN] — frequency of calculation, the template IO;
- this [IN] — reference to the parameter object, what executing the template;
- ctx [IN] — object of the user context, what saved between the execution cycles;
- args [IN] — object of arguments of the procedure;
- items [IN|OUT] — object of items of the SMART.
