Will also indicate where you would find the field wiring connected to Module, and terminal location for each input and output. That the numbers 010-077 and 110-177 are also used to decode the rack, Of the memory map will be discussed later, but first you need to know Will also be assigned to the coils and contacts in the program. Input image table is located at address 110 to 177 (octal). The output image table is located at address 010 to 017 (octal). Is called Processor Work Area 1, and this area is used only by the processor.
Ill.32: Example of Allen-Bradley PLC2 memory and dataįrom the diagram in this figure, you can see the first section of memory A memory map for the permanent memory for the PLC2 is shown The address for each input and output is definedīy the location of inputs and outputs in the permanent internal memory Need to know how to decode its address to find the correct status indicator When you troubleshoot a limit switch that's connected to a terminal on one of the input modules, or a motor starter that's connected to a terminal on one of the output modules, you will If you are technician, you may find it necessary to work on other NEXT: Documenting a PLC Program with Software PREV: Typical Problems a Technician will Encounter Addressing Other Allen-Bradley PLCs Addressing Other Allen-Bradley PLCs Home | Sitemap/Articles
