Logical Addressing
Where: Is the:
# File address identifier. Omit for bit, word, and structure addresses (also indicates indexed addressing, see next
page)
X
File type: B - binary N - integer T - timer MG - message
1
CT - ControlNet Transfer
2
C - counter O - output A - ASCII PD - PID
1
ST - ASCII string
1
F - floating point R - control D - BCD SC - SFC status
1
I - input S - status BT - block transfer
1
F File number: 0 - output 1 - input 2 - status 3 - 999 any other type
: Colon delimiter separates file and structure/word numbers
e Structure/word number: 0 - 277
octal for input/output files
0 - 31 decimal for the status file (Classic PLC-5 processors)
up to: 0 - 127 decimal for the status file
0 - 999 for 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
