Motor Control PLC with a PIC

[sougata]

Hi,

Steve what I intend to do is a PC side software with a Flowcode style of visual programming. (I am not sure how much I can achieve though !!) I will have different routines in PIC and a table generated by the PC side software that will have the different constants (pseudo constants changeable on the PC soft). The table will also have pointers that ties up different subroutines on the PIC to make a logical program flow. The PIC would be a 18F4431 perhaps. Where I am confused is the program blocks on the PC soft, parameters in otherwords. They can be a tacho input followed by a divisor, a programmable timebase, current sensing blocks, protection and so on..... I don't know which blocks should essentially make a smart motor controller. As for sayzer, the motor control part is mostly handled in mixed asm+pbp. Relying on entirely asm interrupts. I may use a dedicated chip for the motor control and another PIC to download PC data and run the app. So if anybody can suggest me what should be the capability of the PC soft then I can start at least. Here is a link where you can download a demo version of the PLC soft for Crouzet millenium-III PLCs http://www.crouzet-usa.com/downloads...um/Demo132.exe
