FB_GetCycleTime \u2013 C\u00e1lculo del tiempo de ciclo en TwinCAT 3<\/p>\n

En esta entrada comparto un bloque sencillo para medir tiempos de ciclo en TwinCAT 3 utilizando una m\u00e1quina de estados muy compacta. Este tipo de bloques es \u00fatil para medir la duraci\u00f3n exacta de operaciones, subrutinas, secuencias o diagn\u00f3sticos dentro del PLC.<\/p>\n

A continuaci\u00f3n el c\u00f3digo completo del Function Block:<\/p>\n

\nFUNCTION_BLOCK FB_GetCycleTime\nVAR_INPUT\niExecute : BOOL;\nEND_VAR\nVAR_OUTPUT\noDone : BOOL;\noCycleTime : LREAL;\nEND_VAR\nVAR\nState : UINT;\nPreviousTime : TIME;\nCycleTime : TIME;\nEND_VAR\n\nCASE State OF\n\n0:\nIF iExecute THEN\nState := 10;\nPreviousTime := TIME();\nEND_IF\n\n10:\nCycleTime := TIME() - PreviousTime;\noCycleTime := TIME_TO_LREAL(CycleTime) \/ 1000.0;\nState := 20;\noDone := TRUE;\n\n20:\nIF NOT iExecute THEN\noDone := FALSE;\nState := 0;\noCycleTime := 0;\nEND_IF\n\nEND_CASE\n<\/pre>\n
Explicaci\u00f3n r\u00e1pida:
\n\u2013 El bloque espera un flanco en iExecute para empezar la medici\u00f3n.
\n\u2013 Captura el tiempo actual como referencia.
\n\u2013 Calcula el tiempo transcurrido y lo entrega en segundos (LREAL).
\n\u2013 Cuando finaliza, activa oDone.
\n\u2013 Si iExecute se desactiva, el bloque se reinicia para una nueva medici\u00f3n.<\/p>\n
