Functional description
When LOGO! is in RUN mode, LOGO! displays the message text that you have configured
along with its parameter values upon a 0 to 1 transition of the signal at input En.
Based on your setting for the message destination, the message text displays on the
LOGO! onboard display, the LOGO! TDE, or both.
If you use flag M27 in your circuit program, then if M27=0 (low) then LOGO! displays the
message text only if it is from the primary character set (Character Set 1). If M27=1 (high),
then LOGO! displays the message text only if it is from the secondary character set
(Character Set 2). (See the M27 flag description in topic Constants and connectors
(Page 115)).
