Addressing I/O and Controller Memory 4-17
Specifying Logical Addresses
The format of a logical address corresponds directly to the location in data
storage: # X F : e . s / b
Where Is the
# File address. Omit for bit, word, and structure addresses (also indicates indexed addressing, see next
page)
X File type:B—binaryN—integerT—timerMG—message
C—counterO—outputA—ASCIIPD—PID
F—floating pointR—controlD—BCDSC—SFC status
I—inputS—statusBT—block-transfer ST—ASCII string
F File number:0—output
1—input
2—status
3-999—any other type
: colon or semicolon delimiter separates file and structure/word numbers
e Structure/word number:0-277octal for input/output files
up to:0-127decimal for the status file
0-999for all the file types except MG, PD, and ST files
. Period delimiter is used only with structure-member mnemonics in counter, timer and control files
s Structure/member mnemonic is used only with timer, counter, control, BT, MG, PD, SC, and ST files
/ Bit delimiter separates bit number
b Bit number:00-07 or 10-17 for input/output files
00-15 for all other files
00-15,999 for binary files when using direct bit address
