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

loadrt message names=oillow,oilpressure,inverterfail messages="Slideway oil low,No oil pressure,Spindle inverter fault"
addf oillow servo-thread
addf oilpressure servo-thread

net no-oil classicladder.0.out-21 oillow.trigger
net no-pressure classicladder.0.out-22 oilpressure.trigger

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