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.

Global Var OnLine As Boolean := True
