4.1 INVOCATION OF MESSAGES BY THE BY
PROG. CONT.
In order to invoke a message or a message text, the coded
message number must simply be placed on the message
inputs. Every time the message number is changed, a new
message is displayed or stored, depending on the messa-
ge variants.
The only condition for correct invocation of a message
is that the message number must be present on the
message inputs for a minimum period.
