Hi Gostenn, FBD, LAD & SCL are finally converted into STL by respective editor before downloading into PLC. STL compiler then converts it to machine code . Please see the order Program simplicity- (highest)FBD-LAD-SCL-STL It is higher level language, most user friendly Speed- (highest) STL-SCL-LAD-FBD STL being lower level or machine language has the great speed. Load of memory- (highest)FBD-LAD-SCL-STL FBD/LAD being higher level consumes lots of memory. As it is vast subject, I also do not have relevant manuals for various applications. U can refer book "Programmable logic controllers: by Gary dunning. Hope this helps. |
