Examples
All addresses are in octal.
PLC-5 /
SoftPLC
Addresses
I:0 Word 0
I:10 Word 8 (10 octal = 8 decimal)
I/20 Bit 16 (20 octal = 16 decimal)
I:1/0 Bit 0 word 1 (same as I/20)
I/20[9] 9 element Boolean array starting at bit 16 (20 octal = 16 decimal)
I/37[8][11] 8 by 11 element Boolean array starting at bit 31 (37 octal = 31 decimal)
I:47/5[3] 3 element Boolean array starting at bit 5 word 39 (47 octal = 39 decimal)
I:11/13[3][7] 3 by 7 element Boolean array starting at bit 11 (13 octal = 11 decimal) word 9 (11 octal = 9
decimal)
