The message number is part of the extended address of the message
procedure. Consider the following extended address:
E5.1.1.24.0
where:
5 designates the message area
1 designates context 1
1 designates the report generation section in the area
24 designates the message number within the section
0 designates the starting word within the message
The starting word must always be 0.
Upon entering the message edit mode, the text of the message procedure
displays, if any exists. Table 7.B shows editing commands for positioning
the cursor and for deleting text. You can type in text to be added to the
message procedure. Characters enter the procedure to the left of the cursor.
To exit the edit mode, press:
[CANCEL COMMAND]
The PLC-3 processor returns the ladder diagram programming display.
You can generate a new procedure in this edit mode. However, you must
place the new procedure name in the symbol table before the 1775-S4B
can edit and/or execute it. Refer to chapter 9 for a discussion on the symbol
table. Simply enter:
IS,,MR.0 [ENTER] [ENTER]
The 1775-S4B scanner inserts the procedure name into the symbol table.
