Forty-Character Message Format
The 40-character message format requires 40 bytes of V memory storage in the
S7-200 CPU for each message. Each message requires both lines of the TD 200
display, allowing only one message to be shown at a time. Figure D-8 shows an
example of how a 40-character message can be formatted in the CPU and
displayed on the TD 200.
