[Scilab-users] CLR design component is not clear in scilab 6.0.2 x64 W10

[Pierre PERRICHON]

Dear,

 

A new time, Federico is right.

Monsieur Pierre-Simon de Lapalce is a French man ==> so the variable of Laplace is p

American are not France, so they use s

Like Grafcet in FRANCE, which is a french conception and SFC in US and their copies several years later.

 

I've done my own componants library in certains case under scilab/xcos, without problem in  5.5.2 and I use p and s in sheme

For me not a problem. But I can take 5 minyes ti explain history during the rush with students.

 

I hope that the last component with CLR will be accepted and retained, so it is so nice, as said by Federico ans Samuel pour the next 6.1

 

Regards

Hello

CLR design component brings confusion by forgetting the * sign in operand

of a polynomial representation in Laplace plan

It makes schemes unreadeable
