Message programming examples
Simple text message
ISPLAY
Ladder instruction
The LCD instruction in DirectSOFT
gives the PLC programmer a convenient
way to define screen messages. A literal
string can be programmed using the
LCD instruction. Embedding variables
allows you to customize the messages for
an application that involves changing
values. The following example shows an
embedded date and time on an alarm
message:
Message with embedded date and time
Message with embedded data
DL06 PLC LCD Display
The top line (16 characters) is designated
K1, and the second line is K2. The
sample instructions on this page show
how a message is developed. A permis-
sive contact turns on the instruction
block, which sends the message to the
display.
Messages can also be retrieved from V-
memory and sent to the display. Select
K1 or K2 to indicate which line you
want to write to and select "From V-
memory" as the source of the string.
Message from PLC memory
Up to 16 characters of ASCII text can be
displayed per line. In the example, K16
indicates that 16 bytes (8 words) of
ASCII text is retrieved for display.
Potential uses
The potential uses for the DL06's LCD
display vary widely. An operator can
change values for setting up batch
processes or machine timing for manu-
facturing
different
products,
Maintenance personnel can interface in
the control cabinet to identify machine
problems. LCD messages can be prepro-
grammed for process events or alarms.
The LCD can satisfy many operator
interface needs at a very cost-effective
price.
