Connecting Customer-Supplied Digital I/O Equipment
Adept SmartController User’s Guide, Rev. K 53
Fast DIO interrupt events (using INT.EVENT) require the optional V
+
Extensions License.
When the program task priorities are properly set, there is a 2 ms maximum latency for
fast inputs 1001 to 1008 when used with the V
+
INT.EVENT instruction.
See the V+ Language Reference Guide for a description of the INT.EVENT instruction.
Output Signals
The XDIO connector handles output signals 0001 to 0008. Refer to Table 3-12 for output
specifications. The locations of the signals on the connector are shown in Table 3-13 on
page 55. The XDIO connector provides separate positive and negative connections for
each channel (no internal common connections). This allows the choice of wiring for
current-sourcing or current-sinking modes.
Figure 3-7 on page 54 shows two examples of different connections to the digital outputs
on the XDIO connector. The examples are negative common and positive common using
the internal 24 V and ground connections.
Example 1: outputs 0001 to 0004 are shown with positive common.
Example 2: outputs 0005 to 0008 are shown with negative common.
NOTE: These are examples. Either method can be used, in any
combination, on any channel. Also, an external customer-provided power
supply could have been provided instead of the power provided on the
XDIO connector.
