O( L DB600.DBB 2 L 0 I ) O “FAULT_DB_PROCESS”.E_Stop O “FAULT_DB_PROCESS”.TT100_HighTemp O “FAULT_DB_PROCESS”.TT101_HighTemp O “FAULT_DB_PROCESS”.TT102_HighTemp O “FAULT_DB_PROCESS”.TT103_HighTemp = “CriticalAlarm”. Se trata de un fragmento de código dentro de un bloque FC; parece tratarse de condiciones de alarma. Me gustaría saber cómo surge esta sintaxis. Gracias

Solo se activará la parada cuando se den alarmas en las tres temperaturas

¿Qué significa O( ), L DB600.DBB, 2 L y 0 I?
Reply #42016-04-28
Se cumple cuando DB600.DBB 2 no es igual a 0

Gracias. Ahora lo sé. O representa la lógica “o”, mientras que I se refiere a la comparación de valores enteros
