Appendix B SLC 500 Data Files and Logical Addressing This appendix provides you with an overview of SLC 500 family data files and logical addressing. It describes: • data files • data file types • data file addressing Data Files Data files contain the status information associated with external I/O and all other instructions you use in your program. In addition, these files store information concerning processor operation.
B-2 SLC 500 Data Files and Logical Addressing Address Structure Data files contain elements. Some data files have 1-word elements, some have 3-word elements. You will be addressing elements, words, and bits. Addresses are made up of alpha-numeric characters separated by delimiters. Delimiters include the colon, slash, and period. Typical element, word, and bit addresses are shown below.
SLC 500 Data Files and Logical Addressing B-3 I/O addresses are assigned to fixed I/O controllers as shown below. Format Explanation O Output I Input : Element delimiter e Slot number (decimal) . Word delimiter. Required only if a word number is necessary as noted below. s Word number Required if the number of inputs or outputs exceeds 16 for the slot. Range: 0-255 (range accomodates multi-word specialty I/O modules).
B-4 SLC 500 Data Files and Logical Addressing I/O addresses are assigned to modular controllers as shown in the table below: Format Explanation O Output I Input : Element delimiter e Slot number (decimal) Slot 0, adjacent to the power supply in the first rack, applies to the processor module (CPU). Succeeding slots are I/O slots, numbered from 1 to a maximum of 30. . Word delimiter. Required only if a word number is necessary as noted below.
SLC 500 Data Files and Logical Addressing B-5 Data File 3 - Bit File 3 is the bit file, used principally for relay logic instructions, shift registers, and sequencers. The maximum size of the file is 256 1-word elements, or a total of 4096 bits. You can address bits by specifying the element number (0-255) and the bit number within the element (0-15). You can also address bits simply by numbering them in sequence, from 0 to 4095. You can also address elements of this file. Bit 14, element 3.
