Functions (by Lewis SF)
Hello, first of all, I would like to thank you for the effort and dedication that you employ in this magnificent program.
The second thing is, ask if you have some kind of special brand that is activated only in the first moment in which the cycle is started?
something similar to the special brand SM0.1 that the Siemens S7-200 PLCs have.
At the moment I am designing processes in Grafcet, and I need something that activates the first stage.

Thank you very much and sorry for the inconvenience, if I do not explain correctly, I am Spanish with low level of English.

esta marca que dices (SM0.1) es un ciclo cuando alimentas el PLC o esta activa siempre que el plc esta con alimentación.
Si es un ciclo puedes colocar (OSR).
Pero si siempre tiene que estar activo mientras tengas alimentación, para leer, escribir, Mover, ETC.
no pongas nada a principio de la linea (a la Izquierda)

---------------------------------------(MOV C1 100)

Otra manera seria.

OSR---------------------------------Set R0.

R0---(y aqui es donde puedes colocar las lineas y peldaños.
