Omron CJ - INSTRUCTIONS REFERENCE MANUAL 07-2009 Reference Manual page 992

Function
When the execution condition is ON, MSG(046) registers the 16 words of ASCII data (up to 32
characters including the null character) from M to M+15 for the message number specified by N. Once
a message has been registered, a Programming Console can be connected and the message will be
displayed after any error messages that have been generated.
After a message has been registered, the message display can be changed by overwriting the
message in the message storage area.
To clear a message that has been registered, execute MSG(046) with S set to the message number of
the message you want to clear and N set to a constant (0000 to FFFF).
A message registered during program execution will be retained even if program execution is stopped,
but all messages will be cleared when the program is executed again.
Precautions
• Registered messages are updated each time MSG(046) is executed.
• All message characters after the null character (00) are converted to spaces in the Programming
Console display.
• The character stored in the leftmost byte is displayed before the character in the rightmost byte.
