Post by sturmghost on Initialization of visualization variables and cyclic code execution ^{CODESYS Forge talk (Post)}
I'm looking for a smart and short way to implement initialization of visualization variables depending on the visualization input. For an easy example consider a rectangle which rests at XPos := 0 when the input state is false and at XPos := 50 when the input state is true. My visualization variables look like this: VAR_IN_OUT State : BOOL; END_VAR VAR XPos : INT; END_VAR I put this rectangle via a visualization frame element into another visualization and link a frame reference variable with the state to it. If the variable is true, the rectangle should rest at XPos := 50 and false at XPos := 0 at visualization init but how should I assign the 50 or 0 to the internal visualization variable XPos? I would need some init-methode for the visualization but I dont want a global init-method for such tasks. I want to do it inside of the visualization element but I can't see any solution for this? It would be good to be able to define ST-code within the visualization element which runs cyclic at each VISU_TASK task-cycle then I could just check the input state and change the XPos accordingly. Does someone have a solution?

Post by kurtk on Modbus TCP Server ^{CODESYS Forge talk (Post)}
ditto I'm just getting my codesys wheels on and the modbus stuff is confusing. I am re-platforming an existing PLC application On that platform one could simply tag variables to register numbers and the whole shooting match could be accessed via modbus and typically holding registers and input registers were treated the same way... On codesys I see there is a modbus TCP server Device I/O mapping tab and a Modbus TCP server IEC objects tab I get the sense that one can configure the serving of variables both/either way but am unclear about the optimum/necessary path. Apparently in the IEC Objects tab one can "ADD" something or other - presumeably channels. I have created a preliminary function block but the Select Function Block window shows nothing to select WTH ? I exported the Device mapping and was surprised to see the entire Device IO map - complete with all the bit-mapped holding/input registers!! WTH!!?? Bit-mapped words are strictly a nichey special purpose application. I am targetting making a couple hundred variables available which would turn into hundreds of pages of IO/mapping Is the FUnction Block IEC objects thingy an alternative to that ? I notice that CODESYS shows the tags which the PLC used to specify the register address... are tags used in CODESYS for any specific hard-core purpose ?
