1. ji The program example in Figure 7 2 illustrates how the function key FI may be used just like a push button or other similar input type device In this instance F1 is used to increment the accumulative value of count up counter C5 1 and initiate a MOVE instruction Each time the FI function key is pressed the accumulated value of the counter increases by one and the MOVE instruction moves the new value to the right hand side of the Keypad display The Destination address of the MOVE instruction is 0 021 which for this configuration is the word in the output image table where integer data is sent to the Keypad Module See Figure 7 1 Input and Output Image Tables Any integer number sent to this word address will be displayed on the Keypad Module display Move instructions aren t the only instructions that may be used to display data on a Keypad Module Logical Arithmetic and some File type instructions may also be used Any method of moving data is acceptable 7 4 Triggering a Stored Message to Describe Data Rung 2 0 Function m Rung 2 1 Key I 020 I F1 Function Chapter 7 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 t
