It is possible to declare, in a function block, an output which is the instance of the same function block.
I' d like to use in my project fucntion blocks orderers (like MC_MoveAbsolute) which accepts the instance of the object to be ordered as an in_out (For example the ordered is the functionBlock Axis_ref_virtual and the orderer is the functionBlock MC_MoveAbsolute).
But I'd dont like use global variables as an in_out to MC_MoveAbsolute (As axes are).
I have made a fucntion block wich controls the movement of a pneumatic cillinder, I'd like that this function block gives an output as an one instance of himsrlf to be connected to the inout input of a functionBlock named FB_setCillinderIn, Because I d'ont like that the instance of the pneumatic cillinder be global.

Thanks Scott. I try that. But if I use this i Will use a copy of my instace, and if i Will use this^ i Will use an pointer. My idea was to use a "reference to" as an output, but Is not possible.
I d like to use t'he same function like axes. I have seen that axes_ref is not an instance of the axes, is an intermediate classe beetwen the axes and t'he orders function blocs (mc move absolutes) i Will use t'he same method.
