NAME

       message - Display a message

SYNOPSIS

       loadrt message [count=N|names=name1[,name2...]] [messages=N]

           messages
                  The  messages  to  display.  These  should be listed, comma-delimited, inside a
                  single set of quotes. See the "Description" section for an example.   If  there
                  are  more  messages than "count" or "names" then the excess will be ignored. If
                  there are fewer messages than "count" or "names" then an error will  be  raised
                  and the component will not load.

DESCRIPTION

       Allows HAL pins to trigger a message. Example hal commands:
        loadrt  message  names=oillow,oilpressure,inverterfail  messages="Slideway oil low,No oil
       pressure,Spindle inverter fault"
        addf oillow servo-thread
        addf oilpressure servo-thread
        addf inverterfail servo-thread

        setp oillow.edge 0 #this pin should be active low
        net no-oil classicladder.0.out-21 oillow.trigger
        net no-pressure classicladder.0.out-22 oilpressure.trigger
        net no-inverter classicladder.0.out-23 inverterfail.trigger

       When any pin goes active, the corresponding message will be displayed.

FUNCTIONS

       message.N
              Display a message

PINS

       message.N.trigger bit in (default: FALSE)
              signal that triggers the message

       message.N.force bit in (default: FALSE)
              A FALSE->TRUE transition forces the message to be displayed again if the trigger is
              active

PARAMETERS
