3.8 Connecting Customer-Supplied Digital I/O Equipment
The SmartController contains two options for connecting Inputs and Outputs (I/O). I/O
can be hard-wired to the XDIO and /or Controller Area Network (CAN) connectors.
DeviceNet Connector
The DeviceNet connector on the SmartController is used to interface to a CAN using the
DeviceNet protocol. See “Adept DeviceNet” on page 115 for more details.
XDIO Connector
The XDIO connector on the SmartController is a 50-pin, standard density D-Sub female
connector (see Figure 3-1 on page 37 for location). There are 12 inputs and 8 outputs, each
optically isolated from the circuitry of the SmartController. The signals are numbered
1001 through 1012 for the inputs and 1 through 8 for the outputs. All the signals have
independent source and ground connections. These inputs contain the four high-speed
inputs that are used by the system for interrupts and latching. The outputs, although
independent, have a lower current rating of 100 mA compared to 700 mA for the extended
outputs on the sDIO (described in Section A.6 on page 104). See the V+ Language User’s
Guide for information on digital I/O programming.
The connector also provides 24 V pins for powering customer equipment. There are four
24 V pins and four ground pins, which are limited to a total of 1 A of current. The source
of the 24 V is the XDC connector on the front of the SmartController.
Input Signals
The XDIO connector handles input signals 1001 to 1012. Each channel has an input and a
corresponding return line. See the following table for input specifications. The connector
pin-outs are shown in Table 3-13 on page 63.
