Memory Register Table

Viewing the Memory Monitor

In order to view the “Memory Monitor in MapleLogic, you have to first go online with your PLC. Once you establish online connection:

• Click the “Memory Monitor” button

In MapleLogic the Memory Monitor puts registers in hexadecimal format

• 0 – F = 1 word

Using a Bit Register in your Ladder Diagram

• Hit F5 or click the “Open Contact” button on the toolbar
• For example use “X25” or “X0025” as the bit register
• Click “OK”

In MapleLogic, if you are using some kind of contact or coil in your logic, the bit register you are using will have a dot to separate the word from the bit.

Example : (X2.5)

Using a Word Register in your Ladder Diagram

Using an ADD Instruction in MapleLogic

• Press F10 or click the ADD Instruction button
• For example type : “ADD X20 D20 D30”, adding the word register “X20” or “X0020” to D20 and storing in D30
• Click “OK”
