* Only the above bit numbers or mnemonics can be read for Timer, Counter or Control file types. No
other bit numbers or mnemonics are allowed. For example, C5:8.CU and C5:8/15 are the same address.
C5:8.ACC/00 is a legitimate address.
_d = Destination address
on the Data Highway. Example: N7:100_2 will read N7:100 from PLC
address 2 on the Data Highway. This feature allows addressing a destination address different than the
one entered as the Destination ID in the AB Data Highway Plus dialog box. Remember that the
destination address is in octal format.
Node address range is 0-377 (octal).
I/O Addressing
The format for I/O addressing differs from the general format. The format is described as:
X:rg/00-17
X = I (input) or O (output)
r = assigned rack number
g = I/O group number
00 - 15
= terminal (bit) number (decimal),
00 - 17 = terminal (bit) number (octal)
Example: O:12/03 = Output, rack 1, group 2, bit 03
Example: I:02/10 = Input, rack 0, group 2, bit 10
Status File Addressing
The format for Status File addressing differs from the general format. The format is described as:
S:e/b
S = Status
e = element number (0-999)
b = bit number (0-15)
Example: S:4/5 = Status register, element 4, bit 05.
