If memory serves, the object is to have the Sequence block
set the DM/FV variable "DMCMD" with the text of a display
manager command.
That variable can be accessed from outside the DM/FV by using
a name which is the DM/FV name followed by the variable name
"DMCMD". So, for FoxView name 05WP01, the variable is named
05WP01DMCMD.
In Sequence code an OM name is preceded by ":", so the statement
to set it is:
: 05WP01DMCMD := "dmcmd msglin Hola"
Be careful to remember that if the DM/FV instance isn't running,
the Sequence block gets a -1 error (because the variable doesn't
exist), also that it will fail the same way if the DM/FV station
is dead or is rebooting, etc. There are also some nodebus conditions
which can also make the command fail, at least temporarily, so it
is a good idea to have an error handler.
