OnCueUnitsOnlineRequest
Scope: Public
Function linked to OnCueUnitsOnlineRequest collects information, if monitored CUEunits are online
(accesible) or not.
Following feature of CVC projects is used there. If you want to get return value of function or variable, which
is placed in another CUEunit and this CUEunit is not accesible (is offline or switched off), you will get zero
value of given data type (for example 0 in case of Long or Double, false in case of Boolean. If unit is online,
you will get real value (you will get Boolean value True in our example).
You must create global boolean variable in Main module of each monitored CUEunit and set value of this
variable to True.
