8-Word Message
This is a 16-character, one-line message. It is a display-only message
requiring no operator response. If data is not being entered, the
message is displayed as soon as it is received by the module. The
message appears on the top line of the display:
• The message remains on the display until it is overwritten by
another message or any module key is pressed.
• When the message is cleared, the screen returns to the previous
display.
The message text is stored in processor memory at the local source
file address that is designated in the message instruction. The table
below describes the message instruction local source file block
layout:
For example: If the Local Source File Address is N7:10, the message is stored in words N7:10
through N7:17.
To enter the message text into processor memory, refer to your
software user manual.
