RIO Hardware Settings
The DynaFlow Interface Module (77377-02) has
several DIP switch settings that establish the op-
erating characteristics of the RIO port.
RIO Rack Address
The RIO Rack Address is used to indicate to which
RIO rack the Interface Module is assigned. RIO
Rack Addresses are specified in octal format.
There are 64 decimal possible Rack Addresses,
which are assigned 00 through 77 octal.
There are five (5) words of discrete inputs and
five (5) words of discrete output possible for each
DynaFlow Interface Module. Each DynaFlow
Interface Module supports up to four (4) Chan-
nel Cards and each Channel Card has two (2)
Channels for a total of eight (8) Channels. The
PLC discrete I/O RIO output bits are logical OR'd
with the discrete I/O hard-wired signals so that
either hard-wired signals or PLC control signals
may control the system. Likewise, the DynaFlow
hard-wired outputs are sent to the PLC via the
discrete I/O RIO inputs.
The DynaFlow system uses two-slot addressing
and appears to a PLC as a collection of 8-bit
modules of I/O. In other words, each module has
8 inputs and 8 outputs. The Interface Module
appears as a single 8-bit I/O module in slot 1,
or the odd slot of a pair of slots. Therefore, the
Interface Module, which reports the System I/O
signals, uses the high byte of word 0.
Each DynaFlow Channel Card appears as two
8-bit I/O modules. The first channel appears in
the low byte and the second channel appears in
the high byte of each successive word in the RIO
discrete I/O space.
With two-slot addressing, each rack contains 8
I/O groups (0-7). The following table describes
how DynaFlow is assigned within a rack.
