to pop up its description (if any).
An instance of this function block type includes the HMI elements and
local multicast
functionality to test an instance of the MECH_VIEW
type. See the DRILL_VIEWL
configuration for examples of its use.
The local multicast channel name, as well as the HMI label, is
specified by the REND_ID input. For convenience, the
default value of this input is "<name>_REND"
, where <name> is the instance name of the MECH_HMIL
instance. This can be overridden by connection to a non-default
variable or configuration parameter.
