allied interface signals are located in the card cage in the left (Standard Output) section of the
main control box.
A tag located in the electric box identifies the boards that may be provided and shows the position
of each board in the card cage. Each 24 output board has a set of red LED's (numbered 0 through
23). Each 16/8 I/O board has two sets of LED's—a red set for the outputs (numbered 0 through 7)
and a green set for the inputs (numbered 0 through 15). The “Board/code” values listed in the
tables herein tell you which board and output or input number represent the indicated signal, as in
the following example:
io2/5
Where:
io2 = the 16/8 I/O board designated “BIO-2”. (Other examples:
io1=BIO-1, o1=BO24-1, o2=BO24-2)
5 = input #5, if this signal is an input or output #5 if this signal is
an output.
5.
Decimal / Binary Conversion and How It Applies to Allied
Interfaces
Batch codes (decimal numbers) are converted to binary by the sending controller, then passed via
the numeric signals to the receiving controller, where they must be converted back to decimal
numbers. For example, if an interface provides for passing 16 drycodes, then to pass drycode 14
(binary 1110), drycode signals D, C, B, and A (from most to least significant) must be on, on, on,
and off respectively, during the “data valid” window.
Table 5 “Numeric Signal Decimal and Binary Values” shows, for the first 16 decimal numbers
(e.g., drycodes 00 through 15), the corresponding binary numbers and which numeric signal
carries each binary digit. This table's columns correspond to, and align with the columns in each
table of numeric signals herein. For higher numbers, use the “Decimal Value of Signal” values in
this table to convert between decimal and binary as explained herein.
