Bit of a newbie here, be gentle
Playing here with a Telemecanique/Schneider Zelio unit.
Can manage ladder program, but totally new to this FBD language but would like to give it a go, so was thinking a practical example like I would use may be the best way to learn.
Example:
If I had two pumps say Q1 and Q2
controlled by 3 float switches with normally open contacts
I1 bottom float switch
I2 middle float switch
I3 top level float switch
When water level reaches I1, i.e contact I1 closes no pump switcheon.s .
When water level reaches I2, i.e contact I2 closes, pump 1 (Q1) switches ON
When water level reaches I3, i.e contact I3 closes pump 2 (Q2) also switches ON
When water level falls below I1 i.e contact I1 opens, both pumps switch OFF
I have figured out how to get the lcd screen to display whatever I like, but was wondering if anyone give me an idea of writing the above example in "good" FBD.
