7.6 Digital I/O Connector
The Digital I/O connector on the SIO is a 50-pin, high-density, D-Sub female connector for
digital I/O communication. There are 12 input channels and 8 output channels. All
channels are opto-isolated. The same connector also provides access to the Emergency
Stop circuit (E-Stop input and Passive E-Stop output). To access this connector, you will
need a cable with a male 50-pin, D-Sub connector at one end (not supplied with the
system). See the section on “Digital I/O Connector Ordering Details (Third-Party
Sources)” on page 91 for more information.
Users requiring additional digital I/O capability may also purchase one or more
64-channel DIO modules (see Chapter 13).
See the optional V
+
Language Reference Guide for information on digital I/O programming
using the SIGNAL instruction, the SIG() and SIG.INS() functions, and related keywords.
See the optional V
+
Operating System Reference Guide for information on the IO and
SIGNAL commands.
Input Signals
The digital I/O connector handles input signals 1001 to 1012. (On systems with the
Manual Mode Safety Package (MMSP) option, input channel 1012 is used by the MMSP
and is not available for users.) Each channel has an input and a corresponding return line.
Refer to Table 7-3 for input specifications. The locations of the signals on the connector are
shown in Table 7-5.
REACT Input Signals 1001 to 1012
Inputs 1001 to 1012 (only) may be also used by the V
+
REACT and REACTI instructions.
See the V
+
Language Reference Guide for information on these instructions. If you are going
to use these instructions, you should plan your digital I/O channel usage accordingly.
(Inputs on the optional DIO module cannot be used by the REACT and REACTI
instructions.)
Fast Input Signals 1001 to 1003
Input signals 1001 to 1003 have several special uses. They can be used for:
• Standard digital I/O (same as 1004 to 1288)
• REACT/REACTI (same as 1004 to 1012)
•Fast DIO V
+
Interrupt Events (INT.EVENT)
• Robot and Encoder Position Latch
• Vision Trigger
Fast DIO Interrupt Events (using INT.EVENT) require an optional V
+
Extensions License.
See the V
+
Language Reference Guide for a description of the INT.EVENT instruction.
The last three functions (events, latch, and trigger) can only be obtained using input
signals 1001 to 1003.
