The message print command is self-terminating. [ESC] or [CANCEL
COMMAND] can be used to return to ladder diagram display.
Accessible in any mode, the message report command is used to print a
message with the current data table value or bit status that corresponds to
an address between the delimiters. This command is accessed by pressing
[M] [R] [,] [message number] [RETURN].
In the example, the message report command would give the following:
(e.g., bit 013/05 is on and counter 030 accumulated value is 5)
SR6 IS ON IN CYCLE 005
The message report command is self-terminating. When [ESC] or
[CANCEL COMMAND] is pressed, ladder diagram operation will resume.
Accessible only in program mode, the message delete command is used to
delete messages from memory. This command is accessed by pressing [M]
[D] [,] [message number] [RETURN].
The message delete command cannot be terminated before completion. It
will self-terminate after the message has been cleared from memory and
a MESSAGE DELETED prompt will be printed. [ESC] or [CANCEL
COMMAND] can be used to return to ladder diagram display.
Accessible in any mode, the message index command prints a list of the
message numbers used and the amount of memory (in words) used for each
message. In addition, the number of unused memory words available will
be listed.
The message index command is accessed by pressing [M] [I] [RETURN].
This command cannot be terminated before completion. It will
self-terminate after the list is completed. To return to ladder diagram
display, press [ESC] or [CANCEL COMMAND].
When entering a message, there are several keys and special industrial
terminal control codes that are used to move through the display and
perform a variety of functions (Tables 9.D and 9.E). For example, graphic
capability can be accessed by the control code, [CTRL] [P] [5] [G]. In
addition, standard ASCII control codes can be used with the industrial
terminal (Table 9.F). These codes, although not displayed, can be
interpreted and acted on by a peripheral device connected to channel C.
