It is possible to use the output of the block. Only it is also connected to the linkeble input. Yer |

Hi DJB , I/O parameter are usually not linkale in CFC, but it's possible use SFC to move that kind of data to other destination (independent from DB istances nr.). Just set SFC properties to "autostart" & "manual" mode and "Cyclic operaition": SFC will startautomatically when plc truns in RUN and it will be executed ciclycally. Regards |

Hi DJB, The method suggested by CBo is one way (though little round about)... The other option is use an FB. I created a sample FB EX_U2 (attached). Connect the PTR_DB parameter of this FB to any output of RATIO_P. Please be aware of the pitfalls of using this "technology":For exampleRATIO_P is changed in future versions in such a way that the absolute position of U2 changes by adding a new parameter before U2. This is highly unlikely but not impossible. Hence use this sparingly. Regards AttachmentEX_U2.ZIP (91 Downloads) |
