Re: CLAD2017 - Fundamentals - Boolean Value and Value Signaling

Active Participant

The value read from a Boolean Value or Value (Signaling) Property Node, can be of either Boolean or Variant type depending on the configuration of the Boolean Terminal?

 

a) TRUE

b) FALSE

TRUE

True (except you can not read from a Value (Signaling) Property).

a) TRUE

Variant will happen when a boolean control is set to latching.

True.

Configuring Value (Signaling) Property with latching mechanical action will always returns an error 1193.

I would say FALSE since the Val(Sig) is a write only property.

nice learned something new: TRUE

 

a) set "latching" operation on a boolean control/indicator will return a Variant via property node (i guess i saw it before but never registered it consciously)
