Hello,
I'm currently working on an automation project with Allen Bradley RSLogix5000, FTView ....
I have a problem with the analog outputs, I have programmed with the feature FBD (Functional Block Diagram) but my license reaches its expiration date so I find myself obliged to reschedule with ladder.
as shown in the figure is an example of a routine with FBD
I tried with "cpt" in ladder but I have received nothing as result
explanation of the Example: I have a valve and i need to control it with 0-100% opening range(Input) and analog output 4-20 mA so all what i want is the implementation to scale (scale) so I started with a linear function y = ax + b and I found this final equation Y = 160X + 4000;
remote_6: 14: O: Ch1Data = 160 + 4000 * Pcv4011.Val_Aut
PS: Y is my output (remote_6: 14: O: Ch1Data) , X: the opening desired (0 -> 100) PCV4011.Aut_Man indicates the automatic or manual mode.
I am at your disposal for any further explanation.
