I was recently telling an engineer about bits/bytes/words and double words in S7.
I drew the following diagram to represent a Marker Word in S7.
With M11.0 being the bit furthest on the right and M10.7 being the bit furthest on the left. I also explained about how to work out in binary the value of the word, with the Least Significant Bit being on the right and the Most Significant Bit being on the left.
He had some Modicon experience (which I don't) and said that the diagram was the same as Modicon except that in Modicon the MSB is on the right and the LSB is on the left...
Can anyone with Modicon experience confirm this? It doesn't sound right to me?
Puzzled from the UK...
