Extended Digital I/O Signals

The extended digital I/O signals are 64 optically isolated digital I/O channels (32
input and 32 output). They are wired to connectors JDIO1 through JDIO4, which
are located on the back of the CIP (see '  
( ). The electrical specifications for
the inputs are similar to the JSIO inputs but have a different wiring configuration.
In addition, they may not be used for REACTI programming, high-speed
interrupts or vision triggers. The outputs have a higher current carrying capacity
than the JSIO.


The signals on the JDIOx connectors can be superseded by a
DIO board that is installed and addressed as DIO board #1. To use
both the JDIOx signals and DIO boards, address the first DIO board
as DIO board #2. See

Extended I/O Inputs

The 32 input channels are arranged in four groups of eight. Each group is
electrically isolated from the other groups and is optically isolated from the CIP
circuitry. The eight inputs within each group share a common ground.
The inputs are accessed through the two 26-pin D-sub input connectors on the
rear of the CIP. Each connector provides access to two input groups. Each group
requires ten pins, eight input signals and two ground references. An input is
activated by providing a positive potential on its input pin relative to the ground
pin of its group. This type of input is considered sinking, that is, to turn it on,
current must flow into the input pin.
