Programming

The Keypad Module is not only capable of displaying numeric data, but also

alphanumeric messages to describe that data. These messages may be stored

in the programmable controller and sent to the Keypad Module via ASCII

code, or store up to 120 messages in the Keypad Module and trigger them

according to their message number. The later method is the most common

means of displaying messages on the Keypad Module.

As described earlier in the System Configuration section, several messages

have already been entered into the Keypad Module.

Figure 7.3 below shows Rung 2:2 has been added to the sample program.

This will trigger a message in the Keypad Module.
